nosave: consolidate __nosave_{begin,end} in

2015-05-06T19:56:28+00:00

commit 7f8998c7aef3ac9c5f3f2943e083dfa6302e90d0 upstream.

The different architectures used their own (and different) declarations:

    extern __visible const void __nosave_begin, __nosave_end;
    extern const void __nosave_begin, __nosave_end;
    extern long __nosave_begin, __nosave_end;

Consolidate them using the first variant in .

MIPS: asm: thread_info: Add _TIF_SECCOMP flag

2014-09-17T16:03:58+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.

MIPS: asm/reg.h: Make 32- and 64-bit definitions available at the same time

2014-09-17T16:03:58+00:00

commit bcec7c8da6b092b1ff3327fd83c2193adb12f684 upstream.

Get rid of the WANT_COMPAT_REG_H test and instead define both the 32-
and 64-bit register offset definitions at the same time with
MIPS{32,64}_ prefixes, then define the existing EF_* names to the
correct definitions for the kernel's bitness.

This patch is a prerequisite of the following bug fix patch.

commit 87c99203fea897fbdd84b681ad9fced2517dcf98 upstream.

The file uses u16 type but doesn't include its definition explicitly

I was getting this error when including this header in my driver:

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

2013-10-18T14:45:45+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: Expose missing pci_io{map,unmap} declarations

2013-08-15T05:59:10+00:00

commit 78857614104a26cdada4c53eea104752042bf5a1 upstream.

The GENERIC_PCI_IOMAP does not depend on CONFIG_PCI so move
it to the CONFIG_MIPS symbol so it's always selected for MIPS.
This fixes the missing pci_iomap declaration for MIPS.
Moreover, the pci_iounmap function was not defined in the
io.h header file if the CONFIG_PCI symbol is not set,
but it should since MIPS is not using CONFIG_GENERIC_IOMAP.

This fixes the following problem on a allyesconfig:

drivers/net/ethernet/3com/3c59x.c:1031:2: error: implicit declaration of
function 'pci_iomap' [-Werror=implicit-function-declaration]
drivers/net/ethernet/3com/3c59x.c:1044:3: error: implicit declaration of
function 'pci_iounmap' [-Werror=implicit-function-declaration]

2013-06-08T18:51:13+00:00

Pull MIPS fixes from Ralf Baechle:
 "MIPS fixes across the field.  The only area that's standing out is the
  exception handling which received it's dose of breakage as part of the
  microMIPS patchset"

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: ralink: add missing SZ_1M multiplier
  MIPS: Compat: Fix cputime_to_timeval() arguments in compat binfmt_elf.
  MIPS: OCTEON: Improve _machine_halt implementation.
  MIPS: rtlx: Fix implicit declaration of function set_vi_handler()
  MIPS: Trap exception handling fixes
  MIPS: Quit exposing Kconfig symbols in uapi headers.
  MIPS: Remove duplicate definition of check_for_high_segbits.

mips/kvm: Fix ABI by moving manipulation of CP0 registers to KVM_{G,S}ET_ONE_REG

2013-06-03T07:58:54+00:00

Because not all 256 CP0 registers are ever implemented, we need a
different method of manipulating them.  Use the
KVM_SET_ONE_REG/KVM_GET_ONE_REG mechanism.

Now unused code and definitions are removed.
