2012-06-12m68k: make syscall_trace_enter/leave exist for non-MMU classic m68k typesGreg Ungerer
The assembler entry code calls directly to the syscall_trace_enter() and syscall_trace_leave() functions. But currently they are conditionaly compiled out for the non-MMU classic m68k CPU types (so 68328 for example), resulting in a link error: LD vmlinux arch/m68k/platform/68328/built-in.o: In function `do_trace': (.text+0x1c): undefined reference to `syscall_trace_enter' arch/m68k/platform/68328/built-in.o: In function `do_trace': (.text+0x4c): undefined reference to `syscall_trace_leave' Change the conditional check that includes these functions to be true for the !defined(CONFIG_MMU) case as well.

2012-06-12m68k: fix inclusion of arch_gettimeoffset for non-MMU 68k classic CPU typesGreg Ungerer
When building for non-MMU based classic 68k CPU types (like the 68328 for example) you get a compilation error: CC arch/m68k/kernel/time.o arch/m68k/kernel/time.c:91:5: error: redefinition of ‘arch_gettimeoffset’ include/linux/time.h:145:19: note: previous definition of ‘arch_gettimeoffset’ was here The arch_gettimeoffset() code is included when building for these CPU types, but it shouldn't be. Those machine types do not have CONFIG_ARCH_USES_GETTIMEOFFSET set. The fix is simply to conditionally include the arch_gettimeoffset() code on that same config setting that specifies its use or not.

McKenney: " This series has four patches, the major point of which is to eliminate some slowdowns (including boot-time slowdowns) resulting from some RCU_FAST_NO_HZ changes. The issue with the changes is that posting timers from the idle loop has no effect if the CPU has entered dyntick-idle mode because the CPU has already computed its wakeup time, and posting a timer does not cause it to be recomputed. The short-term fix is for RCU to precompute the timeout value so that the CPU's calculation is correct. " Signed-off-by: Ingo Molnar <mingo@kernel.org>

2012-06-10r8169: avoid NAPI scheduling delay.françois romieu
While reworking the r8169 driver a few months ago to perform the smallest amount of work in the irq handler, I took care of avoiding any irq mask register operation in the slow work dedicated user context thread. The slow work thread scheduled an extra round of NAPI work which would ultimately set the irq mask register as required, thus keeping such irq mask operations in the NAPI handler. It would eventually race with the irq handler and delay NAPI execution for - assuming no further irq - a whole ksoftirqd period. Mildly a problem for rare link changes or corner case PCI events. The race was always lost after the last bh disabling lock had been removed from the work thread and people started wondering where those pesky "NOHZ: local_softirq_pending 08" messages came from. Actually the irq mask register _can_ be set up directly in the slow work thread.

2012-06-10drm/radeon: fix tiling and command stream checking on evergreen v3Jerome Glisse
Fix regresson since the introduction of command stream checking on evergreen (thread referenced below). Issue is cause by ddx allocating bo with formula width*height*bpp while programming the GPU command stream with ALIGN(height, 8). In some case (where page alignment does not hide the extra size bo should be according to height alignment) the kernel will reject the command stream. This patch reprogram the command stream to slice - 1 (slice is a derivative value from height) which avoid rejecting the command stream while keeping the value of command stream checking from a security point of view. This patch also fix wrong computation of layer size for 2D tiled surface. Which should fix issue when 2D color tiling is enabled. This dump the radeon KMS_DRIVER_MINOR so userspace can know if they are on a fixed kernel or not. https://lkml.org/lkml/2012/6/3/80 https://bugs.freedesktop.org/show_bug.cgi?id=50892 https://bugs.freedesktop.org/show_bug.cgi?id=50857 !!!

2012-06-08mm, oom: fix badness score underflowDavid Rientjes
If the privileges given to root threads (3% of allowable memory) or a negative value of /proc/pid/oom_score_adj happen to exceed the amount of rss of a thread, its badness score overflows as a result of commit a7f638f999ff ("mm, oom: normalize oom scores to oom_score_adj scale only for userspace"). Fix this by making the type signed and return 1, meaning the thread is still eligible for kill, if the value is negative.
