      MAINTAINERS: Become the docs maintainer · ad3118b9
      Jonathan Corbet 提交于
      It seems it's my turn to be the documentation maintainer for a bit.  My
      plan is to work to ensure that docs patches don't fall through the cracks;
      I assume most changes will continue to flow through subsystem-specific
      trees.

      x86,kvm,vmx: Preserve CR4 across VM entry · d974baa3
      Andy Lutomirski 提交于
      CR4 isn't constant; at least the TSD and PCE bits can vary.
      
      TBH, treating CR0 and CR3 as constant scares me a bit, too, but it looks
      like it's correct.
      
      This adds a branch and a read from cr4 to each vm entry.  Because it is
      extremely likely that consecutive entries into the same vcpu will have
      the same host cr4 value, this fixes up the vmcs instead of restoring cr4
      after the fact.  A subsequent patch will add a kernel-wide cr4 shadow,
      reducing the overhead in the common case to just two memory reads and a
      branch.

      futex: Ensure get_futex_key_refs() always implies a barrier · 76835b0e
      Catalin Marinas 提交于
      Commit b0c29f79 (futexes: Avoid taking the hb->lock if there's
      nothing to wake up) changes the futex code to avoid taking a lock when
      there are no waiters. This code has been subsequently fixed in commit
      11d4616b (futex: revert back to the explicit waiter counting code).
      Both the original commit and the fix-up rely on get_futex_key_refs() to
      always imply a barrier.
      
      However, for private futexes, none of the cases in the switch statement
      of get_futex_key_refs() would be hit and the function completes without
      a memory barrier as required before checking the "waiters" in
      futex_wake() -> hb_waiters_pending(). The consequence is a race with a
      thread waiting on a futex on another CPU, allowing the waker thread to
      read "waiters == 0" while the waiter thread to have read "futex_val ==
      locked" (in kernel).
      
      Without this fix, the problem (user space deadlocks) can be seen with
      Android bionic's mutex implementation on an arm64 multi-cluster system.
