• 9984de1a5   kernel: Map most files to use export.h instead of module.h ... Browse Code »

  The changed files were only including linux/module.h for the
  EXPORT_SYMBOL infrastructure, and nothing else. Revector them
  onto the isolated export header for faster compile times.

  Nothing to see here but a whole lot of instances of:

  -#include
  +#include

  This commit is only changing the kernel dir; next targets
  will probably be mm, fs, the arch dirs, etc.

  Instead of using per_cpu(..., raw_smp_processor_id()), use
  __get_cpu_var(...).

• 3c912b6ed   x86: Fix user return notifier put_cpu_var() invocation ... Browse Code »

  Today's linux-next build (x86_64 allmodconfig) failed like this:

  kernel/user-return-notifier.c: In function
  'fire_user_return_notifiers': kernel/user-return-notifier.c:45:
  error: expected expression before ')' token

  Introduced by commit 7c68af6e32c73992bad24107311f3433c89016e2
  ("core, x86: Add user return notifiers") from the tip and kvm trees
  but revealed by commit e0fdb0e050eae331046385643618f12452aa7e73
  ("percpu: add __percpu for sparse") from the percpu tree.

  Before that percpu tree commit, "put_cpu_var()" would compile
  without error (even though it really needs a parameter).

• 7c68af6e3   core, x86: Add user return notifiers ... Browse Code »

  Add a general per-cpu notifier that is called whenever the kernel is
  about to return to userspace. The notifier uses a thread_info flag
  and existing checks, so there is no impact on user return or context
  switch fast paths.

  This will be used initially to speed up KVM task switching by lazily
  updating MSRs.
