2013-04-25arm64: Survive invalid cpu enable-methodsMark Rutland1-4/+4
Currently, if you pass the kernel a dtb where a cpu node has an unsupported enable-method property (e.g. "not-psci"), it'll explode horribly, as it iterates over the enable_ops array incorrectly. It increments the pointer *at* the current element, rather than incrementing the pointer *to* the current element. As the first two elements pointed to structures that were contiguous in memory, this happened to be equivalent. However the third element is NULL, so when the list is exhausted, smp_get_enable_ops generates the wrong pointer, and dereferences an arbitrary portion of memory, which currently happens to contain zero. This patch fixes this by indirecting the pointer one level, so we iterate over the array elements correctly, avoiding the below panic: Signed-off-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2013-04-25arm64: mm: Correct show_pte behaviourSteve Capper1-3/+3
show_pte makes use of the *_none_or_clear_bad style functions. If a pgd, pud or pmd is identified as being bad, it will then be cleared. As show_pte appears to be called from either the user or kernel fault handlers this side effect can lead to unpredictable behaviour; especially as TLB entries are not invalidated. This patch removes the page table sanitisation from show_pte. If a bad pgd, pud or pmd is encountered it is left unmodified.

2013-03-20arm64: kernel: initialise cpu_logical_map from the DTJavi Merino4-7/+121
When booting the kernel, the cpu logical id map must be initialised using device tree data passed by FW or through an embedded blob. This patch parses the reg property in device tree "cpu" nodes, retrieves the corresponding CPUs hardware identifiers (MPIDR) and initialises the cpu logical map accordingly. The device tree HW identifiers are considered valid if all CPU nodes contain a "reg" property, there are no duplicate "reg" entries and the DT defines a CPU node whose "reg" property defines affinity levels that matches those of the boot CPU. The primary CPU is assigned cpu logical number 0 to keep the current convention valid. Based on a0ae02405076ac32bd17ece976e914b5b6075bb0 (ARM: kernel: add device tree init map function).

2013-03-17perf,x86: fix wrmsr_on_cpu() warning on suspend/resumeLinus Torvalds1-1/+3
Commit 1d9d8639c063 ("perf,x86: fix kernel crash with PEBS/BTS after suspend/resume") fixed a crash when doing PEBS performance profiling after resuming, but in using init_debug_store_on_cpu() to restore the DS_AREA mtrr it also resulted in a new WARN_ON() triggering. init_debug_store_on_cpu() uses "wrmsr_on_cpu()", which in turn uses CPU cross-calls to do the MSR update. Which is not really valid at the early resume stage, and the warning is quite reasonable. Now, it all happens to _work_, for the simple reason that smp_call_function_single() ends up just doing the call directly on the CPU when the CPU number matches, but we really should just do the wrmsr() directly instead. This duplicates the wrmsr() logic, but hopefully we can just remove the wrmsr_on_cpu() version eventually.

2013-03-15perf,x86: fix kernel crash with PEBS/BTS after suspend/resumeStephane Eranian2-0/+10
This patch fixes a kernel crash when using precise sampling (PEBS) after a suspend/resume. Turns out the CPU notifier code is not invoked on CPU0 (BP). Therefore, the DS_AREA (used by PEBS) is not restored properly by the kernel and keeps it power-on/resume value of 0 causing any PEBS measurement to crash when running on CPU0. The workaround is to add a hook in the actual resume code to restore the DS Area MSR value. It is invoked for all CPUS. So for all but CPU0, the DS_AREA will be restored twice but this is harmless.

2013-03-13UAPI: fix endianness conditionals in M32R's asm/stat.hDavid Howells1-2/+2
In the UAPI header files, __BIG_ENDIAN and __LITTLE_ENDIAN must be compared against __BYTE_ORDER in preprocessor conditionals where these are exposed to userspace (that is they're not inside __KERNEL__ conditionals). However, in the main kernel the norm is to check for "defined(__XXX_ENDIAN)" rather than comparing against __BYTE_ORDER and this has incorrectly leaked into the userspace headers. The definition of struct stat64 in M32R's asm/stat.h is wrong in this way. Note that userspace will likely interpret the field order incorrectly as the big-endian variant on little-endian machines - depending on header inclusion order. [!!!] NOTE [!!!] This patch may adversely change the userspace API. It might be better to fix the ordering of st_blocks and __pad4 in struct stat64.
