2011-02-16m68knommu: add optimize memmove() functionGreg Ungerer3-2/+107
Add an m68k/coldfire optimized memmove() function for the m68knommu arch. This is the same function as used by m68k. Simple speed tests show this is faster once buffers are larger than 4 bytes, and significantly faster on much larger buffers (4 times faster above about 100 bytes). This also goes part of the way to fixing a regression caused by commit ea61bc461d09e8d331a307916530aaae808c72a2 ("m68k/m68knommu: merge MMU and non-MMU string.h"), which breaks non-coldfire non-mmu builds (which is the 68x328 and 68360 families). They currently have no memmove() fucntion defined, since there was none in the m68knommu/lib functions. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2011-02-16m68k: remove arch specific non-optimized memcmp()Greg Ungerer2-14/+1
The m68k arch implements its own memcmp() function. It is not optimized in any way (it is the most strait forward coding of memcmp you can get). Remove it and use the kernels standard memcmp() implementation. This also goes part of the way to fixing a regression caused by commit ea61bc461d09e8d331a307916530aaae808c72a2 ("m68k/m68knommu: merge MMU and non-MMU string.h"), which breaks non-coldfire non-mmu builds (which is the 68x328 and 68360 families).

2011-02-15sparc64: Fix NMI startup bug which also breaks perf.David S. Miller3-2/+4
Doing NMI startup as an early initcall doesn't work because we need to have SMP started up by then. So we'd only NMI startup one cpu, which causes perf PMU grab to BUG because the nmi_active count isn't what it's supposed to be. This also points out that we don't have proper CPU up/down notifiers for the NMI code which will need to be fixed at some point. Signed-off-by: David S. Miller <davem@davemloft.net>

mp_find_ioapic() prints errors like: ERROR: Unable to locate IOAPIC for GSI 13 if it can't find the IOAPIC that manages that specific GSI. I see errors like that at every boot of a laptop that apparently doesn't have any IOAPICs. But if there are no IOAPICs it doesn't seem to be an error that none can be found. A solution that gets rid of this message is to directly return if nr_ioapics (still) is zero. (But keep returning -1 in that case, so nothing breaks from this change.)

2011-02-09ARM: Avoid building unsafe kernels on OMAP2 and MX3Russell King1-2/+2
OMAP2 (armv6) and MX3 turn off support for the V6K instructions, which when they include support for SMP kernels means that the resulting kernel is unsafe on SMP and can result in corrupted filesystems as we end up using unsafe bitops. Re-enable the use of V6K instructions on such kernels, and let such kernels running on V6 CPUs eat undefined instruction faults which will be much safer than filesystem corruption.

2011-02-09KVM: SVM: Make sure KERNEL_GS_BASE is valid when loading gs_indexJoerg Roedel1-1/+1
The gs_index loading code uses the swapgs instruction to switch to the user gs_base temporarily. This is unsave in an lightweight exit-path in KVM on AMD because the KERNEL_GS_BASE MSR is switches lazily. An NMI happening in the critical path of load_gs_index may use the wrong GS_BASE value then leading to unpredictable behavior, e.g. a triple-fault. This patch fixes the issue by making sure that load_gs_index is called only with a valid KERNEL_GS_BASE value loaded in KVM.

Since mfpr_mmio_base[0] is not always valid on later SoCs, fixed mpfr_sync() to read back from valid mfp offset always. Signed-off-by: Yu Tang <ytang5@marvell.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
2011-02-08sparc: fix size argument to find_next_zero_bit()Akinobu Mita1-3/+2
iommu_alloc_ctx() finds a zero bit in iommu->ctx_bitmap. It starts searching from iommu->ctx_lowest_free to the end of the bitmap. But the size argument to find_next_zero_bit() in iommu_alloc_ctx() is wrong. It should be the bitmap size, not the maximum size to search from the offset argument. Fortunately iommu->ctx_lowest_free is almost unused and it will not be more than 1. So the bug wasted only 1-bit at the end of iommu->ctx_bitmap.

2011-02-08m68knommu: fix use of un-defined _TIF_WORK_MASKGreg Ungerer3-3/+0
The _TIF_WORK_MASK definition was removed in the clean up of MMU and non-MMU arch/m68k/include/asm/thread_info*.h files (this was commit cddafa3500fde4a07e5bf899ec97a04069f8f7ce, "merge MMU and non-MMU thread_info.h"). It didn't get cleaned out of the entry.S code for the 68328 and 68360 based platforms. And it was replaced by a hard coded constant mask for coldfire platforms. There is currently no need to mask any of these bits, so fix all uses (and former uses) to check for any non-zero value. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2011-02-07microblaze: Fix msr instruction detectionMichal Simek2-10/+9
Fix msr instructions detection. The current code just use msrclr for loading msr content and compare it with proper MSR content. If msrclr is not implemented r8 contains pc address. Previous code wanted to use MSR carry bit but if msrclr wasn't implemented carry wasn't cleared. Signed-off-by: Michal Simek <monstr@monstr.eu>
