MIPS: asm: thread_info: Add _TIF_SECCOMP flag

2014-07-11T12:33:56+00:00

commit 137f7df8cead00688524c82360930845396b8a21 upstream.

Add _TIF_SECCOMP flag to _TIF_WORK_SYSCALL_ENTRY to indicate
that the system call needs to be checked against a seccomp filter.

compiler/gcc4: Add quirk for 'asm goto' miscompilation bug

2013-11-28T14:02:03+00:00

commit 3f0116c3238a96bc18ad4b4acefe4e7be32fa861 upstream.

Fengguang Wu, Oleg Nesterov and Peter Zijlstra tracked down
a kernel crash to a GCC bug: GCC miscompiles certain 'asm goto'
constructs, as outlined here:

  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58670

Implement a workaround suggested by Jakub Jelinek.

MIPS: Properly align the .data..init_task section.

commit 7b1c0d26a8e272787f0f9fcc5f3e8531df3b3409 upstream.

Improper alignment can lead to unbootable systems and/or random
crashes.

MIPS: BCM63XX: Add missing include for bcm63xx_gpio.h

2012-06-10T13:41:32+00:00

commit 442209f31dafef9fde852858e1ce566b675b720d upstream.

bcm63xx_gpio.h uses macros defined in bcm63xx_cpu.h without including it,
leading to the following build failure:

MIPS: BCM47xx: fix build with GENERIC_GPIO configuration

2011-11-08T12:35:29+00:00

Since eb9ae7f2 (gpio: fix build error in include/asm-generic/gpio.h)
the generic version of gpio.h calls __gpio_{set,get}_value which we
do not define. Get rid of asm-generic/gpio.h and define the missing
stubs directly for BCM47xx to build.
