[PATCH v2 0/2] Introduce cmpxchg64() and guest_cmpxchg64()

[Julien Grall]

From: Julien Grall <jgr...@amazon.com>

Hi all,

This small series introduced cmpxch64() and guest_cmpxchg64(). This will be
useful when porting IOREQ server to Arm.

Cheers,

Julien Grall (2):
  xen/arm: Remove cmpxchg_local() and drop _mb from the other helpers
  xen: Introduce cmpxchg64() and guest_cmpxchg64()
