2011-02-22KVM: SVM: Advance instruction pointer in dr_interceptJoerg Roedel1-0/+2
In the dr_intercept function a new cpu-feature called decode-assists is implemented and used when available. This code-path does not advance the guest-rip causing the guest to dead-loop over mov-dr instructions. This is fixed by this patch.

2011-02-21ARM: tlb: delay page freeing for SMP and ARMv7 CPUsRussell King1-13/+89
We need to delay freeing any mapped page on SMP and ARMv7 systems to ensure that the data is not accessed by other CPUs, or is used for speculative prefetch with ARMv7. This includes not only mapped pages but also pages used for the page tables themselves. This avoids races with the MMU/other CPUs accessing pages after they've been freed but before we've invalidated the TLB. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-02-21ARM: Keep exit text/data around for SMP_ON_UPRussell King1-0/+9
When SMP_ON_UP is used and the spinlocks are inlined, we end up with inline spinlocks in the exit code, with references from the SMP alternatives section to the exit sections. This causes link time errors. Avoid this by placing the exit sections in the init-discarded region.

2011-02-21ARM: 6740/1: Place correctly notes section in the linker scriptPawel Moll2-1/+3
Commit 18991197b4b588255ccabf472ebc84db7b66a19c added --build-id linker option when toolchain supports it. ARM one does, but for some reason places the section at 0 when linker script doesn't mention it explicitly. The 1e621a8e3752367d4aae78a8ab00a18fb2793f34 worked around the problem removing this section from binary image with explicit objcopy options, but it still exists in vmlinux, confusing tools like debuggers and perf. This problem was discussed here: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html but the proposed changes to the linker script were substantial. This patch simply places NOTES (36 bytes long, at least when compiled with CodeSourcery toolchain) between data and bss, which seem to be the right place (and suggested by the sample linker script in include/asm-generic/vmlinux.lds.h). It is enough to place it correctly in vmlinux (so debuggers are happy): Section Headers: [11] .data PROGBITS c07ce000 7ce000 020fc0 00 WA 0 0 32 [12] .notes NOTE c07eefc0 7eefc0 000024 00 AX 0 0 4 [13] .bss NOBITS c07ef000 7eefe4 01e628 00 WA 0 0 32 Program Headers: LOAD 0x008000 0xc0008000 0xc0008000 0x7e6fe4 0x805628 RWE 0x8000 NOTE 0x7eefc0 0xc07eefc0 0xc07eefc0 0x00024 0x00024 R E 0x4 Section to Segment mapping: Segment Sections... 00 <...> .data .notes .bss 01 .notes and to get it exposed as /sys/kernel/notes used by perf tools.

2011-02-19ARM: 6743/1: errata: interrupted ICALLUIS may prevent completion of broadcasted operationWill Deacon2-0/+16
On versions of the Cortex-A9 prior to r3p0, an interrupted ICIALLUIS operation may prevent the completion of a following broadcasted operation if the second operation is received by a CPU before the ICIALLUIS has completed, potentially leading to corrupted entries in the cache or TLB. This workaround sets a bit in the diagnostic register of the Cortex-A9, causing CP15 maintenance operations to be uninterruptible.

2011-02-19ARM: 6742/1: pmu: avoid setting IRQ affinity on UP systemsWill Deacon1-8/+14
Now that we can execute a CONFIG_SMP kernel on a uniprocessor system, extra care has to be taken in the PMU IRQ affinity setting code to ensure that we don't always fail to initialise. This patch changes the CPU PMU initialisation code so that when we only have a single IRQ, whose affinity can not be changed at the controller, we report success (0) rather than -EINVAL.

2011-02-19ARM: 6741/1: errata: pl310 cache sync operation may be faultySrinidhi Kasagar3-0/+22
The effect of cache sync operation is to drain the store buffer and wait for all internal buffers to be empty. In normal conditions, store buffer is able to merge the normal memory writes within its 32-byte data buffers. Due to this erratum present in r3p0, the effect of cache sync operation on the store buffer still remains when the operation completes. This means that the store buffer is always asked to drain and this prevents it from merging any further writes. This can severely affect performance on the write traffic esp. on Normal memory NC one. The proposed workaround is to replace the normal offset of cache sync operation(0x730) by another offset targeting an unmapped PL310 register 0x740.
