m32r: make memset() global for CONFIG_KERNEL_BZIP2=y

2013-09-14T13:02:11+00:00

commit 9a75c6e5240f7edc5955e8da5b94bde6f96070b3 upstream.

Fix the m32r compile error:

  arch/m32r/boot/compressed/misc.c:31:14: error: static declaration of 'memset' follows non-static declaration
  make[5]: *** [arch/m32r/boot/compressed/misc.o] Error 1
  make[4]: *** [arch/m32r/boot/compressed/vmlinux] Error 2

by removing the static keyword.

m32r: add memcpy() for CONFIG_KERNEL_GZIP=y

2013-09-14T13:02:11+00:00

commit a8abbca6617e1caa2344d2d38d0a35f3e5928b79 upstream.

Fix the m32r link error:

    LD      arch/m32r/boot/compressed/vmlinux
  arch/m32r/boot/compressed/misc.o: In function `zlib_updatewindow':
  misc.c:(.text+0x190): undefined reference to `memcpy'

  make[5]: *** [arch/m32r/boot/compressed/vmlinux] Error 1

by adding our own implementation of memcpy().

m32r: consistently use "suffix-$(...)"

2013-09-14T13:02:11+00:00

commit df12aef6a19bb2d69859a94936bda0e6ccaf3327 upstream.

Commit a556bec9955c ("m32r: fix arch/m32r/boot/compressed/Makefile")
changed "$(suffix_y)" to "$(suffix-y)", but didn't update any location
where "suffix_y" is set, causing:

  make[5]: *** No rule to make target `arch/m32r/boot/compressed/vmlinux.bin.', needed by `arch/m32r/boot/compressed/piggy.o'.  Stop.
  make[4]: *** [arch/m32r/boot/compressed/vmlinux] Error 2
  make[3]: *** [zImage] Error 2

Correct the other locations to fix this.

signal: Define __ARCH_HAS_SA_RESTORER so we know whether to clear sa_restorer

2013-04-05T17:04:14+00:00

Vaguely based on upstream commit 574c4866e33d 'consolidate kernel-side
struct sigaction declarations'.

flush_signal_handlers() needs to know whether sigaction::sa_restorer
is defined, not whether SA_RESTORER is defined.  Define the
__ARCH_HAS_SA_RESTORER macro to indicate this.

m32r: Add missing RCU idle APIs on idle loop

2012-10-12T20:38:55+00:00

commit 48ae077cfce72591b8fc80e1dcc87806f86fed7f upstream.

In the old times, the whole idle task was considered
as an RCU quiescent state. But as RCU became more and
more successful overtime, some RCU read side critical
section have been added even in the code of some
architectures idle tasks, for tracing for example.

So nowadays, rcu_idle_enter() and rcu_idle_exit() must
be called by the architecture to tell RCU about the part
in the idle loop that doesn't make use of rcu read side
critical sections, typically the part that puts the CPU
in low power mode.

This is necessary for RCU to find the quiescent states in
idle in order to complete grace periods.

Add this missing pair of calls in the m32r's idle loop.

Merge branch 'x86-x32-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2012-03-30T01:12:23+00:00

Pull x32 support for x86-64 from Ingo Molnar:
 "This tree introduces the X32 binary format and execution mode for x86:
  32-bit data space binaries using 64-bit instructions and 64-bit kernel
  syscalls.

  This allows applications whose working set fits into a 32 bits address
  space to make use of 64-bit instructions while using a 32-bit address
  space with shorter pointers, more compressed data structures, etc."
