ipc: use Kconfig options for __ARCH_WANT_[COMPAT_]IPC_PARSE_VERSION

2012-07-31T00:25:21+00:00

Rather than #define the options manually in the architecture code, add
Kconfig options for them and select them there instead.  This also allows
us to select the compat IPC version parsing automatically for platforms
using the old compat IPC interface.

h8300/uaccess: remove assignment to __gu_val in unhandled case of get_user()

2012-07-11T23:04:45+00:00

__gu_val is const if the passed ptr is const, giving:

  include/linux/pagemap.h: In function 'fault_in_pages_readable':
  include/linux/pagemap.h:442:2: error: assignment of read-only variable '__gu_val'
  include/linux/pagemap.h:448:4: error: assignment of read-only variable '__gu_val'
  include/linux/pagemap.h: In function 'fault_in_multipages_readable':
  include/linux/pagemap.h:499:3: error: assignment of read-only variable '__gu_val'
  include/linux/pagemap.h:508:3: error: assignment of read-only variable '__gu_val'
  make[4]: *** [init/main.o] Error 1

As we don't care about the actual value of __gu_val in the unhandled
case (it will cause a link error anyway), just remove the assignment.

Merge branch 'next' of git://git.kernel.org/pub/scm/virt/kvm/kvm

2012-05-24T23:17:30+00:00

Pull KVM changes from Avi Kivity:
 "Changes include additional instruction emulation, page-crossing MMIO,
  faster dirty logging, preventing the watchdog from killing a stopped
  guest, module autoload, a new MSI ABI, and some minor optimizations
  and fixes.  Outside x86 we have a small s390 and a very large ppc
  update.

  Regarding the new (for kvm) rebaseless workflow, some of the patches
  that were merged before we switch trees had to be rebased, while
  others are true pulls.  In either case the signoffs should be correct
  now."

Fix up trivial conflicts in Documentation/feature-removal-schedule.txt
arch/powerpc/kvm/book3s_segment.S and arch/x86/include/asm/kvm_para.h.

I suspect the kvm_para.h resolution ends up doing the "do I have cpuid"
check effectively twice (it was done differently in two different
commits), but better safe than sorry ;)

Pull first series of signal handling cleanups from Al Viro:
 "This is just the first part of the queue (about a half of it);
  assorted fixes all over the place in signal handling.

  This one ends with all sigsuspend() implementations switched to
  generic one (->saved_sigmask-based).

  With this, a bunch of assorted old buglets are fixed and most of the
  missing bits of NOTIFY_RESUME hookup are in place.  Two more fixes sit
  in arm and um trees respectively, and there's a couple of broken ones
  that need obvious fixes - parisc and avr32 check TIF_NOTIFY_RESUME
  only on one of two codepaths; fixes for that will happen in the next
  series"

fork: move the real prepare_to_copy() users to arch_dup_task_struct()

2012-05-16T22:16:26+00:00

Historical prepare_to_copy() is mostly a no-op, duplicated for majority of
the architectures and the rest following the x86 model of flushing the extended
register state like fpu there.

Remove it and use the arch_dup_task_struct() instead.

kvmclock: Add functions to check if the host has stopped the vm

2012-04-08T09:48:59+00:00

When a host stops or suspends a VM it will set a flag to show this.  The
watchdog will use these functions to determine if a softlockup is real, or the
result of a suspended VM.
