[Xen-devel] [GIT PULL] x86: paravirt_ops updates
Hi Ingo,
This series has a some changes to x86 paravirt_ops:
x86/paravirt: split paravirt definitions into paravirt_types.h
Move all the type-like definitions into asm/paravirt_types.h
x86: split out core __math_state_restore
Split out the core of math_state_restore() into __math_state_restore(),
which just does what's needed for a context switch (ie, assumes
TS is already clear, and that the fpu context exists).
x86-32: make sure clts is batched during context switch
x86-64: move unlazy_fpu() into lazy cpu state part of context switch
x86-64: move clts into batch cpu state updates when preloading fpu
Make sure the TS state updates during context switch are performed in
the lazy CPU update region so that they can be batched when running
paravirtualized.
The following changes since commit 9ce5424d75e56891905b77d1589924765e62059a:
Ingo Molnar (1):
