      clean statfs-like syscalls up · c8b91acc
      由 Al Viro 提交于 
      New helpers: user_statfs() and fd_statfs(), taking userland pathname and
descriptor resp. and filling struct kstatfs.  Syscalls of statfs family
(native, compat and foreign - osf and hpux on alpha and parisc resp.)
switched to those.  Removes some boilerplate code, simplifies cleanup
on errors...

      futex: Sanitize futex ops argument types · 8d7718aa
      由 Michel Lespinasse 提交于 
      Change futex_atomic_op_inuser and futex_atomic_cmpxchg_inatomic
prototypes to use u32 types for the futex as this is the data type the
futex core code uses all over the place.

      futex: Sanitize cmpxchg_futex_value_locked API · 37a9d912
      由 Michel Lespinasse 提交于 
      The cmpxchg_futex_value_locked API was funny in that it returned either
the original, user-exposed futex value OR an error code such as -EFAULT.
This was confusing at best, and could be a source of livelocks in places
that retry the cmpxchg_futex_value_locked after trying to fix the issue
by running fault_in_user_writeable().
    
This change makes the cmpxchg_futex_value_locked API more similar to the
get_futex_value_locked one, returning an error code and updating the
original value through a reference argument.

      alpha: Change do_timer() to xtime_update() · 1340f3e0
      由 Torben Hohn 提交于 
      xtime_update() takes the xtime_lock itself.

timer_interrupt() is only called on the boot cpu. See do_entInt(). So
"state" in timer_interrupt does not require protection by xtime_lock.
