Who knew? - Make sure we don't divide by zero when doing debugfs dumps of rbtrees, not visible up until now because everything was providing at least some cache on startup. * tag 'regmap-3.4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: prevent division by zero in rbtree_show regmap: Export regcache_sync_region() 07 April 2012, 16:56:00 UTC

e1c4038 Mark Rustad 03 April 2012, 17:24:41 UTC tcm_fc: Add abort flag for gracefully handling exchange timeout Add abort flag and use it to terminate processing when an exchange is timed out or is reset. The abort flag is used in place of the transport_generic_free_cmd function call in the reset and timeout cases, because calling that function in that context would free memory that was in use. The aborted flag allows the lifetime to be managed in a more normal way, while truncating the processing. This change eliminates a source of memory corruption which manifested in a variety of ugly ways.

f68e556 Linus Torvalds 06 April 2012, 20:54:56 UTC Make the "word-at-a-time" helper functions more commonly usable I have a new optimized x86 "strncpy_from_user()" that will use these same helper functions for all the same reasons the name lookup code uses them. This is preparation for that. This moves them into an architecture-specific header file. It's architecture-specific for two reasons: - some of the functions are likely to want architecture-specific implementations. Even if the current code happens to be "generic" in the sense that it should work on any little-endian machine, it's likely that the "multiply by a big constant and shift" implementation is less than optimal for an architecture that has a guaranteed fast bit count instruction, for example. - I expect that if architectures like sparc want to start playing around with this, we'll need to abstract out a few more details (in particular the actual unaligned accesses). So we're likely to have more architecture-specific stuff if non-x86 architectures start using this. (and if it turns out that non-x86 architectures don't start using this, then having it in an architecture-specific header is still the right thing to do, of course) Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 06 April 2012, 20:54:56 UTC

Fix from Eric Dumazet. 11) do_tcp_sendpage() unloads the send queue way too fast, because it invokes tcp_push() when it shouldn't. Let the natural sequence generated by the splice paths, and the assosciated MSG_MORE settings, guide the tcp_push() calls. Otherwise what goes out of TCP is spaghetti and doesn't batch effectively into GSO/TSO clusters. From Eric Dumazet. 12) Once we put a SKB into either the netlink receiver's queue or a socket error queue, it can be consumed and freed up, therefore we cannot touch it after queueing it like that. Fixes from Eric Dumazet. 13) PPP has this annoying behavior in that for every transmit call it immediately stops the TX queue, then calls down into the next layer to transmit the PPP frame. But if that next layer can take it immediately, it just un-stops the TX queue right before returning from the transmit method. Besides being useless work, it makes several facilities unusable, in particular things like the equalizers. Well behaved devices should only stop the TX queue when they really are full, and in PPP's case when it gets backlogged to the downstream device. David Woodhouse therefore fixed PPP to not stop the TX queue until it's downstream can't take data any more. 14) IFF_UNICAST_FLT got accidently lost in some recent stmmac driver changes, re-add. From Marc Kleine-Budde. 15) Fix link flaps in ixgbe, from Eric W. Multanen. 16) Descriptor writeback fixes in e1000e from Matthew Vick. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (47 commits) net: fix a race in sock_queue_err_skb() netlink: fix races after skb queueing doc, net: Update ndo_start_xmit return type and values doc, net: Remove instruction to set net_device::trans_start doc, net: Update netdev operation names doc, net: Update documentation of synchronisation for TX multiqueue doc, net: Remove obsolete reference to dev->poll ethtool: Remove exception to the requirement of holding RTNL lock MAINTAINERS: update for Marvell Ethernet drivers bonding: properly unset current_arp_slave on slave link up phonet: Check input from user before allocating tcp: tcp_sendpages() should call tcp_push() once ipv6: fix array index in ip6_mc_add_src() mlx4: allocate just enough pages instead of always 4 pages stmmac: re-add IFF_UNICAST_FLT for dwmac1000 bnx2x: Clear MDC/MDIO warning message bnx2x: Fix BCM57711+BCM84823 link issue bnx2x: Clear BCM84833 LED after fan failure bnx2x: Fix BCM84833 PHY FW version presentation bnx2x: Fix link issue for BCM8727 boards. ... 06 April 2012, 17:37:38 UTC

0ee46ec Jan Beulich 02 April 2012, 14:32:22 UTC xen/pciback: fix XEN_PCI_OP_enable_msix result Prior to 2.6.19 and as of 2.6.31, pci_enable_msix() can return a positive value to indicate the number of vectors (less than the amount requested) that can be set up for a given device. Returning this as an operation value (secondary result) is fine, but (primary) operation results are expected to be negative (error) or zero (success) according to the protocol. With the frontend fixed to match the XenoLinux behavior, the backend can now validly return zero (success) here, passing the upper limit on the number of vectors in op->value.

That function calls mp_find_ioapics to get the 'struct ioapic' structure - which along with the mp_irq[x] is used to figure out the default values and the polarity/trigger overrides. Since the mp_find_ioapics now returns -1 [b/c the IOAPIC is filled with 0xffffffff], the acpi_get_override_irq() stops trying to lookup in the mp_irq[x] the proper INT_SRV_OVR and we can't install the SCI interrupt. The proper fix for this is going in v3.5 and adds an x86_io_apic_ops struct so that platforms can override it. But for v3.4 lets carry this work-around. This patch does that by providing a slightly different variant of the fake IOAPIC entries. Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> 06 April 2012, 16:13:06 UTC

3bdc9ba Paul Walmsley 12 March 2012, 10:58:00 UTC mmc: use really long write timeout to deal with crappy cards Several people have noticed that crappy SD cards take much longer to complete multiple block writes than the 300ms that Linux specifies. Try to work around this by using a three second write timeout instead. This is a generalized version of a patch from Chase Maupin <Chase.Maupin@ti.com>, whose patch description said: * With certain SD cards timeouts like the following have been seen due to an improper calculation of the dto value: mmcblk0: error -110 transferring data, sector 4126233, nr 8, card status 0xc00 * By removing the dto calculation and setting the timeout value to the maximum specified by the SD card specification part A2 section 2.2.15 these timeouts can be avoided. * This change has been used by beagleboard users as well as the Texas Instruments SDK without a negative impact. * There are multiple discussion threads about this but the most relevant ones are: * http://talk.maemo.org/showthread.php?p=1000707#post1000707 * http://www.mail-archive.com/linux-omap@vger.kernel.org/msg42213.html * Original proposal for this fix was done by Sukumar Ghoral of Texas Instruments * Tested using a Texas Instruments AM335x EVM Signed-off-by: Paul Walmsley <paul@pwsan.com> Tested-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Chris Ball <cjb@laptop.org> 06 April 2012, 00:32:34 UTC

The driver should not try to switch to 1.8V when the SD 3.0 host controller does not have any UHS capabilities bits set (SDR50, DDR50 or SDR104). See page 72 of "SD Specifications Part A2 SD Host Controller Simplified Specification Version 3.00" under "1.8V Signaling Enable". Instead of setting SDR12 and SDR25 in the host capabilities data structure for all V3.0 host controllers, only set them if SDR104, SDR50 or DDR50 is set in the host capabilities register. This will prevent the switch to 1.8V later.

According to eMMC specification, valid voltage for high voltage cards is 2.7v to 3.6v. This patch ensures that 2.7v to 3.6v VDD range is treated as valid range. Also, failure to set the power class shouldn't be treated as fatal error because even if setting the power class fails, card can still work in default power class. If mmc_select_powerclass() returns error, just print the warning message and go ahead with rest of the card initialization.

e841a7c Rafael J. Wysocki 01 April 2012, 04:34:58 UTC mmc: sdio: Use empty system suspend/resume callbacks at the bus level Neil Brown reports that commit 35cd133c PM: Run the driver callback directly if the subsystem one is not there breaks suspend for his libertas wifi, because SDIO has a protocol where the suspend method can return -ENOSYS and this means "There is no point in suspending, just turn me off". Moreover, the suspend methods provided by SDIO drivers are not supposed to be called by the PM core or bus-level suspend routines (which aren't presend for SDIO). Instead, when the SDIO core gets to suspend the device's ancestor, it calls the device driver's suspend function, catches the ENOSYS, and turns the device off. The commit above breaks the SDIO core's assumption that the device drivers' callbacks won't be executed if it doesn't provide any bus-level callbacks. If fact, however, this assumption has never been really satisfied, because device class or device type suspend might very well use the driver's callback even without that commit. The simplest way to address this problem is to make the SDIO core tell the PM core to ignore driver callbacks, for example by providing no-operation suspend/resume callbacks at the bus level for it, which is implemented by this change.

3119936 Thomas Abraham 16 February 2012, 13:23:58 UTC mmc: sdhci-s3c: Remove usage of clk_type member in platform data SDHCI controllers on Exynos4 do not include the sdclk divider as per the sdhci controller specification. This case can be represented using the sdhci quirk SDHCI_QUIRK_NONSTANDARD_CLOCK instead of using an additional enum type definition 'clk_types'. Hence, usage of clk_type member in platform data is removed and the sdhci quirk is used. In addition to that, since this qurik is SoC specific, driver data is introduced to represent controllers on SoC's that require this quirk.

Add a new internal flag, MSG_SENDPAGE_NOTLAST, acting like MSG_MORE, but with different semantic. For all sendpage() providers, its a transparent change.

dac23b0 Michal Hocko 05 April 2012, 21:25:16 UTC memcg swap: use mem_cgroup_uncharge_swap fix Although mem_cgroup_uncharge_swap has an empty placeholder for !CONFIG_CGROUP_MEM_RES_CTLR_SWAP the definition is placed in the CONFIG_SWAP ifdef block so we are missing the same definition for !CONFIG_SWAP which implies !CONFIG_CGROUP_MEM_RES_CTLR_SWAP. This has not been an issue before, because mem_cgroup_uncharge_swap was not called from !CONFIG_SWAP context. But Hugh Dickins has a cleanup patch to call __mem_cgroup_commit_charge_swapin which is defined also for !CONFIG_SWAP. Let's move both the empty definition and declaration outside of the CONFIG_SWAP block to avoid the following compilation error: mm/memcontrol.c: In function '__mem_cgroup_commit_charge_swapin': mm/memcontrol.c:2837: error: implicit declaration of function 'mem_cgroup_uncharge_swap' if CONFIG_SWAP is disabled.

Quoted comments from Al: "Note that unregister_filesystem() in module init is *always* wrong; it's not an issue here (it's done too early to care about and realistically the box is not going anywhere - it'll panic when attempt to exec /sbin/init fails, if not earlier), but it's a damn bad example. Consider a normal fs module. Somebody loads it and in parallel with that we get a mount attempt on that fs type. It comes between register and failure exits that causes unregister; at that point we are screwed since grabbing a reference to module as done by mount is enough to prevent exit, but not to prevent the failure of init. As the result, module will get freed when init fails, mounted fs of that type be damned." So remove it.

b82c328 Anton Vorontsov 05 April 2012, 21:25:05 UTC sysrq: use SEND_SIG_FORCED instead of force_sig() Change send_sig_all() to use do_send_sig_info(SEND_SIG_FORCED) instead of force_sig(SIGKILL). With the recent changes we do not need force_ to kill the CLONE_NEWPID tasks. And this is more correct. force_sig() can race with the exiting thread, while do_send_sig_info(group => true) kill the whole process. Some more notes from Oleg Nesterov: > Just one note. This change makes no difference for sysrq_handle_kill(). > But it obviously changes the behaviour sysrq_handle_term(). I think > this is fine, if you want to really kill the task which blocks/ignores > SIGTERM you can use sysrq_handle_kill(). > > Even ignoring the reasons why force_sig() is simply wrong here, > force_sig(SIGTERM) looks strange. The task won't be killed if it has > a handler, but SIG_IGN can't help. However if it has the handler > but blocks SIGTERM temporary (this is very common) it will be killed. Also, > force_sig() can't kill the process if the main thread has already > exited. IOW, it is trivial to create the process which can't be > killed by sysrq. So, this patch fixes the issue.

1ac02d7 Rob Herring 04 April 2012, 22:48:04 UTC ARM: fix __io macro for PCMCIA With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was broken. PCMCIA depends on __io() returning a valid i/o address, and most ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This needs a better fix with a fixed i/o address mapping, but for now we just restore things to the previous behavior. This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled, but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff, so it doesn't need an io.h.

Basically the regulators must be per board file as the regulators can also come from drivers, such as twl4030. So it's best to dumb down gpmc-smsc911x.c to not even care about the regulators. * 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP: fix section mismatches in usb-host.c ARM: OMAP2+: Fix omap2+ build error ARM: OMAP2+: smsc911x: Add fixed board regulators ARM: OMAP2+: smsc911x: Remove regulator support from gmpc-smsc911x ARM: OMAP2+: smsc911x: Remove unused rate calculation ARM: OMAP2+ smsc911x: Fix possible stale smsc911x flags ARM: OMAP2+: smsc911x: Remove odd gpmc_cfg/board_data redirection ARM: OMAP3+: fix oops triggered in omap_prcm_register_chain_handler(v1) ARM: OMAP2+: OPP: allow OPP enumeration to continue if device is not present arm: omap3: pm34xx.c: Replace printk() with appropriate pr_*() arm: omap3: pm34xx.c: Fix omap3_pm_init() error out paths ARM: OMAP4: Workaround the OCP synchronisation issue with 32K synctimer.
