microblaze:allmodconfig complains for some configurations that 'heartbeat' is redefined as different kind of symbol.

2014-03-07x86: fix compile error due to X86_TRAP_NMI use in asm filesLinus Torvalds
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).

2014-03-07x86: Ignore NMIs that come in during early bootH. Peter Anvin
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.

Commit 017f161a55b4 (ARM: 7877/1: use built-in byte swap function) added bswapsdi2.{o,S} to arch/arm/boot/compressed/Makefile, but didn't update the .gitignore. Thus after a a build git status shows bswapsdi2.S as a new file, which is a little annoying.

2014-03-07ARM: 7991/1: sa1100: fix compile problem on CollieLinus Walleij
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".

2014-03-07ARM: fix noMMU kallsyms symbol filteringRussell King
With noMMU, CONFIG_PAGE_OFFSET was not being set correctly. As there's no MMU, PAGE_OFFSET should be equal to PHYS_OFFSET in all cases. This commit makes that explicit. Since we do this, we don't need to mess around in asm/memory.h with ifdefs to sort this out, so let's get rid of that, and there's no point offering the "Memory split" option for noMMU as that's meaningless there.

2014-03-07powerpc/tm: Fix crash when forking inside a transactionMichael Neuling
When we fork/clone we currently don't copy any of the TM state to the new thread. This results in a TM bad thing (program check) when the new process is switched in as the kernel does a tmrechkpt with TEXASR FS not set. Also, since R1 is from userspace, we trigger the bad kernel stack pointer detection. So we end up with something like this: Bad kernel stack pointer 0 at c0000000000404fc cpu 0x2: Vector: 700 (Program Check) at [c00000003ffefd40] pc: c0000000000404fc: restore_gprs+0xc0/0x148 lr: 0000000000000000 sp: 0 msr: 9000000100201030 current = 0xc000001dd1417c30 paca = 0xc00000000fe00800 softe: 0 irq_happened: 0x01 pid = 0, comm = swapper/2 WARNING: exception is not recoverable, can't continue The below fixes this by flushing the TM state before we copy the task_struct to the clone. To do this we go through the tmreclaim patch, which removes the checkpointed registers from the CPU and transitions the CPU out of TM suspend mode. Hence we need to call tmrechkpt after to restore the checkpointed state and the TM mode for the current task. To make this fail from userspace is simply: tbegin li r0, 2 sc <boom> Kudos to Adhemerval Zanella Neto for finding this.

2014-03-06x86, trace: Further robustify CR2 handling vs tracingPeter Zijlstra
Building on commit 0ac09f9f8cd1 ("x86, trace: Fix CR2 corruption when tracing page faults") this patch addresses another few issues: - Now that read_cr2() is lifted into trace_do_page_fault(), we should pass the address to trace_page_fault_entries() to avoid it re-reading a potentially changed cr2. - Put both trace_do_page_fault() and trace_page_fault_entries() under CONFIG_TRACING. - Mark both fault entry functions {,trace_}do_page_fault() as notrace to avoid getting __mcount or other function entry trace callbacks before we've observed CR2. - Mark __do_page_fault() as noinline to guarantee the function tracer does get to see the fault.

2014-03-04x86, trace: Fix CR2 corruption when tracing page faultsJiri Olsa
The trace_do_page_fault function trigger tracepoint and then handles the actual page fault. This could lead to error if the tracepoint caused page fault. The original cr2 value gets lost and the original page fault handler kills current process with SIGSEGV. This happens if you record page faults with callchain data, the user part of it will cause tracepoint handler to page fault: # perf record -g -e exceptions:page_fault_user ls Fixing this by saving the original cr2 value and using it after tracepoint handler is done. v2: Moving the cr2 read before exception_enter, because it could trigger tracepoint as well.

2014-03-03ARM: XEN depends on having a MMUUwe Kleine-König
arch/arm/xen/enlighten.c (and maybe others) use MMU-specific functions like pte_mkspecial which are only available on MMU builds. So let XEN depend on MMU.

2014-02-28ARM: tegra: add LED options back into tegra_defconfigStephen Warren
The last time tegra_defconfig was rebuilt, various LEDs options were somehow selected by other options, and hence their entries in tegra_defconfig were removed by "make savedefconfig". However, for some reason this is no longer happening, so we need to add the entries back into tegra_defconfig so the they are enabled in .config.

This patch is based on commit: 016c12d2 ("ARM: OMAP3: Fix hardware detection for omap3630 when booted with device tree") and fixes a boot hang due the IGEP board being wrongly initialized as an OMAP3430 platform instead of an OMAP3630.

2014-02-28arm64: mm: Add double logical invert to pte accessorsSteve Capper
Page table entries on ARM64 are 64 bits, and some pte functions such as pte_dirty return a bitwise-and of a flag with the pte value. If the flag to be tested resides in the upper 32 bits of the pte, then we run into the danger of the result being dropped if downcast. For example: gather_stats(page, md, pte_dirty(*pte), 1); where pte_dirty(*pte) is downcast to an int. This patch adds a double logical invert to all the pte_ accessors to ensure predictable downcasting.
