[Xen-devel] [PATCH 0/3] x86: fixes/improvements for scratch cpumask

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Hello,

Commit:

5500d265a2a8fa63d60c08beb549de8ec82ff7a5
x86/smp: use APIC ALLBUT destination shorthand when possible

Introduced a bogus usage of the scratch cpumask: it was used in a
function that could be called from interrupt context, and hence using
the scratch cpumask there is not safe. Patch #2 is a fix for that usage.

Patch #3 adds some debug infrastructure to make sure the scratch cpumask
is used in the right context, and hence should prevent further missuses.

Thanks, Roger.

Roger Pau Monne (3):
  x86/smp: unify header includes in smp.h
  x86/smp: use a dedicated scratch cpumask in send_IPI_mask
  x86: add accessors for scratch cpu mask
