81711ce arch/tile: handle rt_sigreturn() more cleanly The current tile rt_sigreturn() syscall pattern uses the common idiom of loading up pt_regs with all the saved registers from the time of the signal, then anticipating the fact that we will clobber the ABI "return value" register (r0) as we return from the syscall by setting the rt_sigreturn return value to whatever random value was in the pt_regs for r0. However, this breaks in our 64-bit kernel when running "compat" tasks, since we always sign-extend the "return value" register to properly handle returned pointers that are in the upper 2GB of the 32-bit compat address space. Doing this to the sigreturn path then causes occasional random corruption of the 64-bit r0 register. Instead, we stop doing the crazy "load the return-value register" hack in sigreturn. We already have some sigreturn-specific assembly code that we use to pass the pt_regs pointer to C code. We extend that code to also set the link register to point to a spot a few instructions after the usual syscall return address so we don't clobber the saved r0. Now it no longer matters what the rt_sigreturn syscall returns, and the pt_regs structure can be cleanly and completely reloaded.

bc4cf2b arch/tile: handle CLONE_SETTLS in copy_thread(), not user space Previously we were just setting up the "tp" register in the new task as started by clone() in libc. However, this is not quite right, since in principle a signal might be delivered to the new task before it had its TLS set up. (Of course, this race window still exists for resetting the libc getpid() cached value in the new task, in principle. But in any case, we are now doing this exactly the way all other architectures do it.) This change is important for 2.6.37 since the tile glibc we will be submitting upstream will not set TLS in user space any more, so it will only work on a kernel that has this fix. It should also be taken for 2.6.36.x in the stable tree if possible. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> Cc: stable <stable@kernel.org> 17 December 2010, 21:56:50 UTC

587f0d5 [media] bttv: fix mutex use before init (BZ#24602) Fix a regression where bttv driver causes oopses when loading, since it were using some non-initialized mutexes. While it would be possible to fix the issue, there are some other lock troubles, like to the presence of lock code at free_btres_lock(). It is possible to fix, but the better is to just use the core-assisted locking schema. This way, V4L2 core will serialize access to all ioctl's/open/close/mmap/read/poll operations, avoiding to have two processes accessing the hardware at the same time. Also, as there's just one lock, instead of 3, there's no risk of dead locks. The net result is a cleaner code, with just one lock.

The experiment described here shows Windows 7 ignoring the last 1MB: https://bugzilla.kernel.org/show_bug.cgi?id=23542#c27 This patch ignores the top 2MB instead of just 1MB because H. Peter Anvin says "There will be ROM at the top of the 32-bit address space; it's a fact of the architecture, and on at least older systems it was common to have a shadow 1 MiB below." Acked-by: H.

4dc2287 x86: avoid E820 regions when allocating address space When we allocate address space, e.g., to assign it to a PCI device, don't allocate anything mentioned in the BIOS E820 memory map. On recent machines (2008 and newer), we assign PCI resources from the windows described by the ACPI PCI host bridge _CRS. On many Dell machines, these windows overlap some E820 reserved areas, e.g., BIOS-e820: 00000000bfe4dc00 - 00000000c0000000 (reserved) pci_root PNP0A03:00: host bridge window [mem 0xbff00000-0xdfffffff] If we put devices at 0xbff00000, they don't work, probably because that's really RAM, not I/O memory. This patch prevents that by removing the 0xbfe4dc00-0xbfffffff area from the "available" resource. I'm not very happy with this solution because Windows solves the problem differently (it seems to ignore E820 reserved areas and it allocates top-down instead of bottom-up; details at comment 45 of the bugzilla below). That means we're vulnerable to BIOS defects that Windows would not trip over. For example, if BIOS described a device in ACPI but didn't mention it in E820, Windows would work fine but Linux would fail. Reference: https://bugzilla.kernel.org/show_bug.cgi?id=16228 Acked-by: H.

30919b0 x86: avoid low BIOS area when allocating address space This implements arch_remove_reservations() so allocate_resource() can avoid any arch-specific reserved areas. This currently just avoids the BIOS area (the first 1MB), but could be used for E820 reserved areas if that turns out to be necessary. We previously avoided this area in pcibios_align_resource(). This patch moves the test from that PCI-specific path to a generic path, so *all* resource allocations will avoid this area. Acked-by: H.

fcb1191 resources: add arch hook for preventing allocation in reserved areas This adds arch_remove_reservations(), which an arch can implement if it needs to protect part of the address space from allocation. Sometimes that can be done by just putting a region in the resource tree, but there are cases where that doesn't work well. For example, x86 BIOS E820 reservations are not related to devices, so they may overlap part of, all of, or more than a device resource, so they may not end up at the correct spot in the resource tree.

1cf215a ARM: mach-shmobile: INTC interrupt priority level demux fix Fix interrupt priority level handling on SH-Mobile ARM. SH-Mobile ARM platforms using multiple interrupt priority levels need this patch to fix a potential dead lock that may occur if multiple interrupts with different levels are pending simultaneously. The default INTC configuration is to use the same priority level for all interrupts, so this issue does not trigger by default. It is however common for board code to override the interrupt priority for certain interrupt sources depending on the application. Without this fix such boards may lock up. In detail, this patch updates the INTC code in entry-macro.S to make sure that the INTLVLA register gets set as expected. To trigger this bug modify the board specific code to adjust the interrupt priority level for the ethernet chip. After changing the priority level simply use flood ping to drown the board with interrupts. This patch applies to INTCA-based processors such as sh7372, sh7377 and sh7372. GIC-based processors are not affected. Suitable for v2.6.37-rc and stable from v2.6.34 to v2.6.36.

DM needs this to avoid setting queue_limits' max_hw_sectors and max_sectors directly. dm_set_device_limits() now leverages blk_limits_max_hw_sectors() logic to establish the appropriate max_hw_sectors minimum (PAGE_SIZE). Fixes issue where DM was incorrectly setting max_sectors rather than max_hw_sectors (which caused dm_merge_bvec()'s max_hw_sectors check to be ineffective).

e692cb6 block: Deprecate QUEUE_FLAG_CLUSTER and use queue_limits instead When stacking devices, a request_queue is not always available. This forced us to have a no_cluster flag in the queue_limits that could be used as a carrier until the request_queue had been set up for a metadevice. There were several problems with that approach. First of all it was up to the stacking device to remember to set queue flag after stacking had completed. Also, the queue flag and the queue limits had to be kept in sync at all times. We got that wrong, which could lead to us issuing commands that went beyond the max scatterlist limit set by the driver. The proper fix is to avoid having two flags for tracking the same thing. We deprecate QUEUE_FLAG_CLUSTER and use the queue limit directly in the block layer merging functions. The queue_limit 'no_cluster' is turned into 'cluster' to avoid double negatives and to ease stacking. Clustering defaults to being enabled as before. The queue flag logic is removed from the stacking function, and explicitly setting the cluster flag is no longer necessary in DM and MD.

49c2fa0 PCI: Update MCP55 quirk to not affect non HyperTransport variants I wrote this quirk awhile ago to properly setup MCP55 chips on hypertransport busses so that interrupts reached whatever cpu happend to boot the kdump kernel. while that works well, it was recently shown to me that a a non-hypertransport variant of the MCP55 exists, and on those system the register that this quirk manipulates causes hangs if you write to it. Since the quirk was only meant to handle errors found on MCP55 chips that have a HT interface, this patch adds a filter to make sure the chip is an HT capable before making the needed register adjustment. This lets the broken MCP55s work with kdump while not breaking the non-HT variants. Resolves https://bugzilla.kernel.org/show_bug.cgi?id=23952 Tested successfully by the reporter and myself.

82b8915 MIPS: LD/SD o32 macro GAS fix update I am about to commit: http://sourceware.org/ml/binutils/2010-10/msg00033.html that fixes a problem with the LD/SD macro currently implemented by GAS for the o32 ABI in an inconsistent way. This is best illustrated with a simple program, which I'm copying here from the message above for easier reference: $ cat ld.s ld $5,32767($4) ld $5,32768($4) This gets assebled into the following output: $ mips-linux-as -32 -mips3 -o ld.o ld.s $ mips-linux-objdump -d ld.o ld.o: file format elf32-tradbigmips Disassembly of section .text: 00000000 <.text>: 0: dc857fff ld a1,32767(a0) 4: 3c010001 lui at,0x1 8: 00810821 addu at,a0,at c: 8c258000 lw a1,-32768(at) 10: 8c268004 lw a2,-32764(at) ... Oops! The GAS fix makes the macro behave in a consistent way and pairs of LW/SW instructions to be output as appropriate regardless of the size of the offset associated with the address used. The machine instruction is still available, but to reach it macros have to be disabled first. This has a side effect of requiring the use of a machine-addressable memory operand. As some platforms require 64-bit operations for accesses to some I/O registers LD/SD instructions are used in a couple of places in Linux regardless of the ABI selected. Here's a fix for some pieces of code affected I've been able to track down. The fix should be backwards compatible with all supported binutils releases in existence and can be used as a reference for any other places or off-tree code. The use of the "R" constraint guarantees a machine-addressable operand. Signed-off-by: Maciej W.

5878fc9 MIPS: Fix CP0 COUNTER clockevent race Consider the following test case: write_c0_compare(read_c0_count()); Even if the counter doesn't increment during execution, this might not generate an interrupt until the counter wraps around. The CPU may perform the comparison each time CP0 COUNT increments, not when CP0 COMPARE is written. If mips_next_event() is called with a very small delta, and CP0 COUNT increments during the calculation of "cnt += delta", it is possible that CP0 COMPARE will be written with the current value of CP0 COUNT. If this is detected, the function should return -ETIME, to indicate that the interrupt might not have actually gotten scheduled.

e5674ad MIPS: Separate two consecutive loads in memset.S partial_fixup is used in noreorder block. Separating two consecutive loads can save one cycle on processors with GPR intrelock and can fix load-use on processors that need a load delay slot. Also do so for fwd_fixup. [Ralf: Only R2000/R3000 class processors are lacking the the load-user interlock and even some of those got it retrofitted. With R2000/R3000 being fairly uncommon these days the impact of this bug should be minor.] Signed-off-by: Tony Wu <tung7970@gmail.com> To: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/1768/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> 16 December 2010, 18:10:57 UTC
515b029 MIPS: Send proper signal and siginfo on FP emulator faults. We were unconditionally sending SIGBUS with an empty siginfo on FP emulator faults. This differs from what happens when real floating point hardware would get a fault. For most faults we need to send SIGSEGV with the faulting address filled in in the struct siginfo.

0bc6791 MIPS: AR7: Fix loops per jiffies on TNETD7200 devices TNETD7200 run their CPU clock faster than the default CPU clock we assume. In order to have the correct loops per jiffies settings, initialize clocks right before setting mips_hpt_frequency. As a side effect, we can no longer use msleep in clocks.c which requires other parts of the kernel to be initialized, so replace these with mdelay.

Add a check for a null return and then return -ENOMEM in that case. [Ralf: The check added by Jesper's original patch is where it logically should be.
