cbbfa38 Tejun Heo 25 August 2011, 17:46:56 UTC mtrr: fix UP breakage caused during switch to stop_machine While removing custom rendezvous code and switching to stop_machine, commit 192d8857427d ("x86, mtrr: use stop_machine APIs for doing MTRR rendezvous") completely dropped mtrr setting code on !CONFIG_SMP breaking MTRR settting on UP. Fix it by removing the incorrect CONFIG_SMP.

e096d0c Josh Boyer 25 August 2011, 11:48:12 UTC lockdep: Add helper function for dir vs file i_mutex annotation Purely in-memory filesystems do not use the inode hash as the dcache tells us if an entry already exists. As a result, they do not call unlock_new_inode, and thus directory inodes do not get put into a different lockdep class for i_sem. We need the different lockdep classes, because the locking order for i_mutex is different for directory inodes and regular inodes. Directory inodes can do "readdir()", which takes i_mutex *before* possibly taking mm->mmap_sem (due to a page fault while copying the directory entry to user space). In contrast, regular inodes can be mmap'ed, which takes mm->mmap_sem before accessing i_mutex. The two cases can never happen for the same inode, so no real deadlock can occur, but without the different lockdep classes, lockdep cannot understand that. As a result, if CONFIG_DEBUG_LOCK_ALLOC is set, this can lead to false positives from lockdep like below: find/645 is trying to acquire lock: (&mm->mmap_sem){++++++}, at: [<ffffffff81109514>] might_fault+0x5c/0xac but task is already holding lock: (&sb->s_type->i_mutex_key#15){+.+.+.}, at: [<ffffffff81149f34>] vfs_readdir+0x5b/0xb4 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (&sb->s_type->i_mutex_key#15){+.+.+.}: [<ffffffff8108ac26>] lock_acquire+0xbf/0x103 [<ffffffff814db822>] __mutex_lock_common+0x4c/0x361 [<ffffffff814dbc46>] mutex_lock_nested+0x40/0x45 [<ffffffff811daa87>] hugetlbfs_file_mmap+0x82/0x110 [<ffffffff81111557>] mmap_region+0x258/0x432 [<ffffffff811119dd>] do_mmap_pgoff+0x2ac/0x306 [<ffffffff81111b4f>] sys_mmap_pgoff+0x118/0x16a [<ffffffff8100c858>] sys_mmap+0x22/0x24 [<ffffffff814e3ec2>] system_call_fastpath+0x16/0x1b -> #0 (&mm->mmap_sem){++++++}: [<ffffffff8108a4bc>] __lock_acquire+0xa1a/0xcf7 [<ffffffff8108ac26>] lock_acquire+0xbf/0x103 [<ffffffff81109541>] might_fault+0x89/0xac [<ffffffff81149cff>] filldir+0x6f/0xc7 [<ffffffff811586ea>] dcache_readdir+0x67/0x205 [<ffffffff81149f54>] vfs_readdir+0x7b/0xb4 [<ffffffff8114a073>] sys_getdents+0x7e/0xd1 [<ffffffff814e3ec2>] system_call_fastpath+0x16/0x1b This patch moves the directory vs file lockdep annotation into a helper function that can be called by in-memory filesystems and has hugetlbfs call it.

be27425 Andi Kleen 19 August 2011, 23:15:10 UTC Add a personality to report 2.6.x version numbers I ran into a couple of programs which broke with the new Linux 3.0 version. Some of those were binary only. I tried to use LD_PRELOAD to work around it, but it was quite difficult and in one case impossible because of a mix of 32bit and 64bit executables. For example, all kind of management software from HP doesnt work, unless we pretend to run a 2.6 kernel. $ uname -a Linux svivoipvnx001 3.0.0-08107-g97cd98f #1062 SMP Fri Aug 12 18:11:45 CEST 2011 i686 i686 i386 GNU/Linux $ hpacucli ctrl all show Error: No controllers detected. $ rpm -qf /usr/sbin/hpacucli hpacucli-8.75-12.0 Another notable case is that Python now reports "linux3" from sys.platform(); which in turn can break things that were checking sys.platform() == "linux2": https://bugzilla.mozilla.org/show_bug.cgi?id=664564 It seems pretty clear to me though it's a bug in the apps that are using '==' instead of .startswith(), but this allows us to unbreak broken programs. This patch adds a UNAME26 personality that makes the kernel report a 2.6.40+x version number instead. The x is the x in 3.x. I know this is somewhat ugly, but I didn't find a better workaround, and compatibility to existing programs is important. Some programs also read /proc/sys/kernel/osrelease. This can be worked around in user space with mount --bind (and a mount namespace) To use: wget ftp://ftp.kernel.org/pub/linux/kernel/people/ak/uname26/uname26.c gcc -o uname26 uname26.c ./uname26 program Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 25 August 2011, 17:17:28 UTC

ff35336 Kevin Hilman 25 August 2011, 13:31:14 UTC OMAP: omap_device: only override _noirq methods, not normal suspend/resume Commit c03f007a8bf0e092caeb6856a5c8a850df10b974 (OMAP: PM: omap_device: add system PM methods for PM domain handling) mistakenly used SET_SYSTEM_SLEEP_PM_OPS() when trying to configure custom methods for the PM domains noirq methods. Fix that by setting only the suspend_noirq and resume_noirq methods with custom versions. Note that all other PM domain methods (including the "normal" suspend/resume methods) are populated using USE_PLATFORM_PM_SLEEP_OPS, which configures them all to the default subsystem (platform_bus) methods.

Usages are performed through memcmp() and memcpy() directly. Fix those by using the already copied msg_sys structure instead of the __user *msg structure. Note that msg_sys can be set to NULL by verify_compat_iovec() or verify_iovec(), which requires additional NULL pointer checks.

caca951 Linus Torvalds 24 August 2011, 22:55:30 UTC firmware loader: allow builtin firmware load even if usermodehelper is disabled In commit a144c6a6c924 ("PM: Print a warning if firmware is requested when tasks are frozen") we not only printed a warning if somebody tried to load the firmware when tasks are frozen - we also failed the load. But that check was done before the check for built-in firmware, and then when we disallowed usermode helpers during bootup (commit 288d5abec831: "Boot up with usermodehelper disabled"), that actually means that built-in modules can no longer load their firmware even if the firmware is built in too. Which used to work, and some people depended on it for the R100 driver. So move the test for usermodehelper_is_disabled() down, to after checking the built-in firmware.

Without this patch Suspend-to-RAM hangs on the boards AP4EVB and Mackerel. The code hangs in the LCDC driver where the software is waiting forever for the hardware to power down. By explicitly associating the HDMI clock with LCDC1 we can make sure the HDMI clock is enabled using Runtime PM whenever the driver is accessing the hardware. This HDMI and LCDC1 dependency is documented in the sh7372 data sheet. Older kernels did work as expected but the recently merged (3.1-rc) 794d78f drivers: sh: late disabling of clocks V2 introduced code to turn off clocks lacking software reference which happens to include the HDMI clock that is needed by LCDC1 to operate as expected.

Consequently, the Ventana entry is being removed from arch/arm/tools/mach-types in the next merge window, since it was registered over a year ago. This will also remove function machine_is_ventana(), which is used by the ASoC Tegra WM8903 machine driver. This will cause compilation failures. Drop Ventana support to resolve this. Hopefully, in the not-too-distant future, tegra_wm8903.c will be able to configure itself from Device-Tree, and hence we'll be able to re-instate Ventana support just by creating a .dts file for the board. Also note that Aebl support is in a similar boat. However, that board isn't scheduled for deprecation for at least another 5 months, and perhaps we will have completely removed non-Device-Tree support from tegra_wm8903.c by then and/or adjusted mach-types policy.

The function will needlessly bail out without decrementing back the runtime PM reference counter. 2. wl1271_power_on only checks if wl1271_power_on return value is negative. This means that wl1271_power_on will continue even if wl1271_sdio_power_on bailed out. As a result, sdio transactions will be initiated without properly enabling the sdio function and claiming the host. This could even lead to a kernel panic. Fix this by only checking that the return value of pm_runtime_get_sync is non-negative. Signed-off-by: Ido Yariv <ido@wizery.com> Acked-by: Luciano Coelho <coelho@ti.com> Signed-off-by: John W.

80900d0 Ido Yariv 22 August 2011, 20:19:48 UTC wl12xx: Remove obsolete testmode NVS push command The testmode NVS push command is no longer in use. In addition, it has several implementation issues that prevent it from working correctly: 1. wl1271_tm_cmd_configure relies on wl->chip.id being set. However, since the device was not necessarily booted by the time the function is called, wl->chip.id will be initialized to 0. 2. The NVS file is fetched by calling request_firmware() before it is possible to push an NVS file. 3. The maximum allowed size of nl binary payloads is not sufficient for pushing NVS files. 4. Pushing 128x NVS files will always fail due to a bug in the validation code. 5. In case the pushed NVS file is found invalid, the mutex will be kept locked and the nvs member will become a dangling pointer. Since this feature is not being used, remove it completely instead of fixing it. Signed-off-by: Ido Yariv <ido@wizery.com> Acked-by: Luciano Coelho <coelho@ti.com> Signed-off-by: John W.

69dd3d8 Linus Torvalds 23 August 2011, 17:36:51 UTC Revert "irq: Always set IRQF_ONESHOT if no primary handler is specified" This reverts commit f3637a5f2e2eb391ff5757bc83fb5de8f9726464. It turns out that this breaks several drivers, one example being OMAP boards which use the on-board OMAP UARTs and the omap-serial driver that will not boot to userspace after the commit. Paul Walmsley reports that enabling CONFIG_DEBUG_SHIRQ reveals 'IRQ handler type mismatch' errors: IRQ handler type mismatch for IRQ 74 current handler: serial idle ... and the reason is that setting IRQF_ONESHOT will now result in those interrupt handlers having different IRQF flags, and thus being unsharable. So the commit log in the reverted commit: "Since it is required for those users and there is no difference for others it makes sense to add this flag unconditionally." is simply not true: there may not be any difference from a "actions at irq time", but there is a *big* difference wrt this flag testing irq management (see __setup_irq() in kernel/irq/manage.c). One solution may be to stop verifying IRQF_ONESHOT in __setup_irq(), but right now the safe course of action is to revert the change. Let's revisit this in a later merge window.

24d406a Jiri Slaby 10 August 2011, 12:59:28 UTC TTY: pty, fix pty counting tty_operations->remove is normally called like: queue_release_one_tty ->tty_shutdown ->tty_driver_remove_tty ->tty_operations->remove However tty_shutdown() is called from queue_release_one_tty() only if tty_operations->shutdown is NULL. But for pty, it is not. pty_unix98_shutdown() is used there as ->shutdown. So tty_operations->remove of pty (i.e. pty_unix98_remove()) is never called. This results in invalid pty_count. I.e. what can be seen in /proc/sys/kernel/pty/nr. I see this was already reported at: https://lkml.org/lkml/2009/11/5/370 But it was not fixed since then. This patch is kind of a hackish way. The problem lies in ->install. We allocate there another tty (so-called tty->link). So ->install is called once, but ->remove twice, for both tty and tty->link. The fix here is to count both tty and tty->link and divide the count by 2 for user. And to have ->remove called, let's make tty_driver_remove_tty() global and call that from pty_unix98_shutdown() (tty_operations->shutdown). While at it, let's document that when ->shutdown is defined, tty_shutdown() is not called. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: Alan Cox <alan@linux.intel.com> Cc: "H.

dbb3b1c Al Cooper 25 July 2011, 20:19:52 UTC 8250: Fix race condition in serial8250_backup_timeout(). This is to fix an issue where output will suddenly become very slow. The problem occurs on 8250 UARTS with the hardware bug UART_BUG_THRE. BACKGROUND For normal UARTs (without UART_BUG_THRE): When the serial core layer gets new transmit data and the transmitter is idle, it buffers the data and calls the 8250s' serial8250_start_tx() routine which will simply enable the TX interrupt in the IER register and return. This should immediately fire a THRE interrupt and begin transmitting the data. For buggy UARTs (with UART_BUG_THRE): merely enabling the TX interrupt in IER does not necessarily generate a new THRE interrupt. Therefore, a background timer periodically checks to see if there is pending data, and starts transmission if that is the case. The bug happens on SMP systems when the system has nothing to transmit, the transmit interrupt is disabled and the following sequence occurs: - CPU0: The background timer routine serial8250_backup_timeout() starts and saves the state of the interrupt enable register (IER) and then disables all interrupts in IER. NOTE: The transmit interrupt (TI) bit is saved as disabled. - CPU1: The serial core gets data to transmit, grabs the port lock and calls serial8250_start_tx() which enables the TI in IER. - CPU0: serial8250_backup_timeout() waits for the port lock. - CPU1: finishes (with TI enabled) and releases the port lock. - CPU0: serial8250_backup_timeout() calls the interrupt routine which will transmit the next fifo's worth of data and then restores the IER from the previously saved value (TI disabled). At this point, as long as the serial core has more transmit data buffered, it will not call serial8250_start_tx() again and the background timer routine will slowly transmit the data. The fix is to have serial8250_start_tx() get the port lock before it saves the IER state and release it after restoring IER. This will prevent serial8250_start_tx() from running in parallel.
