commit 8ceee72808d1ae3fb191284afc2257a2be964725 upstream. The GHASH setkey() function uses SSE registers but fails to call kernel_fpu_begin()/kernel_fpu_end().

commit 825600c0f20e595daaa7a6dd8970f84fa2a2ee57 upstream. On x86 uniprocessor systems topology_physical_package_id() returns -1 which causes rapl_cpu_prepare() to leave rapl_pmu variable uninitialized which leads to GPF in rapl_pmu_init(). See arch/x86/kernel/cpu/perf_event_intel_rapl.c. It turns out that physical_package_id and core_id can actually be retreived for uniprocessor systems too. Enabling them also fixes rapl_pmu code.

2014-03-23x86, fpu: Check tsk_used_math() in kernel_fpu_end() for eager FPUSuresh Siddha
commit 731bd6a93a6e9172094a2322bd0ee964bb1f4d63 upstream. For non-eager fpu mode, thread's fpu state is allocated during the first fpu usage (in the context of device not available exception). This (math_state_restore()) can be a blocking call and hence we enable interrupts (which were originally disabled when the exception happened), allocate memory and disable interrupts etc. But the eager-fpu mode, call's the same math_state_restore() from kernel_fpu_end(). The assumption being that tsk_used_math() is always set for the eager-fpu mode and thus avoid the code path of enabling interrupts, allocating fpu state using blocking call and disable interrupts etc. But the below issue was noticed by Maarten Baert, Nate Eldredge and few others: If a user process dumps core on an ecrypt fs while aesni-intel is loaded, we get a BUG() in __find_get_block() complaining that it was called with interrupts disabled; then all further accesses to our ecrypt fs hang and we have to reboot. The aesni-intel code (encrypting the core file that we are writing) needs the FPU and quite properly wraps its code in kernel_fpu_{begin,end}(), the latter of which calls math_state_restore(). So after kernel_fpu_end(), interrupts may be disabled, which nobody seems to expect, and they stay that way until we eventually get to __find_get_block() which barfs. For eager fpu, most the time, tsk_used_math() is true. At few instances during thread exit, signal return handling etc, tsk_used_math() might be false. In kernel_fpu_end(), for eager-fpu, call math_state_restore() only if tsk_used_math() is set. Otherwise, don't bother. Kernel code path which cleared tsk_used_math() knows what needs to be done with the fpu state.

commit 596f3142d2b7be307a1652d59e7b93adab918437 upstream. We always disable cr8 intercept in its handler, but only re-enable it if handling KVM_REQ_EVENT, so there can be a window where we do not intercept cr8 writes, which allows an interrupt to disrupt a higher priority task.

commit b01d4e68933ec23e43b1046fa35d593cefcf37d1 upstream. It's an enum, not a #define, you can't use it in asm files. Introduced in commit 5fa10196bdb5 ("x86: Ignore NMIs that come in during early boot"), and sadly I didn't compile-test things like I should have before pushing out. My weak excuse is that the x86 tree generally doesn't introduce stupid things like this (and the ARM pull afterwards doesn't cause me to do a compile-test either, since I don't cross-compile).

2014-03-23x86: Ignore NMIs that come in during early bootH. Peter Anvin
commit 5fa10196bdb5f190f595ebd048490ee52dddea0f upstream. Don Zickus reports: A customer generated an external NMI using their iLO to test kdump worked. Unfortunately, the machine hung. Disabling the nmi_watchdog made things work. I speculated the external NMI fired, caused the machine to panic (as expected) and the perf NMI from the watchdog came in and was latched. My guess was this somehow caused the hang. ---- It appears that the latched NMI stays latched until the early page table generation on 64 bits, which causes exceptions to happen which end in IRET, which re-enable NMI. Therefore, ignore NMIs that come in during early execution, until we have proper exception handling.

2014-03-23ARM: 7991/1: sa1100: fix compile problem on CollieLinus Walleij
commit 052450fdc55894a39fbae93d9bbe43947956f663 upstream. Due to a problem in the MFD Kconfig it was not possible to compile the UCB battery driver for the Collie SA1100 system, in turn making it impossible to compile in the battery driver. (See patch "mfd: include all drivers in subsystem menu".) After fixing the MFD Kconfig (separate patch) a compile error appears in the Collie battery driver due to the <mach/collie.h> implicitly requiring <mach/hardware.h> through <linux/gpio.h> via <mach/gpio.h> prior to commit 40ca061b "ARM: 7841/1: sa1100: remove complex GPIO interface". Fix this up by including the required header into <mach/collie.h>.

2014-03-23powerpc: Align p_dyn, p_rela and p_st symbolsAnton Blanchard
commit a5b2cf5b1af424ee3dd9e3ce6d5cea18cb927e67 upstream. The 64bit relocation code places a few symbols in the text segment. These symbols are only 4 byte aligned where they need to be 8 byte aligned. Add an explicit alignment.

2014-03-23ARM: 7811/1: locks: use early clobber in arch_spin_trylockWill Deacon
commit afa31d8eb86fc2f25083e675d57ac8173a98f999 upstream. The res variable is written before we've finished with the input operands (namely the lock address), so ensure that we mark it as `early clobber' to avoid unintended register sharing.

2014-03-13arm64: ptrace: fix compat registes get/set to be endian cleanMatthew Leach
On a BE system the wrong half of the X registers is retrieved/written when attempting to get/set the value of aarch32 registers through ptrace. Ensure that types are the correct width so that the relevant casting occurs.
