[PATCH v3 4/9] x86/mm/tlb: Flush remote and local TLBs concurrently
...n calls and the indirect branch introduce some overhead, and
might make local TLB flushes slower than they were before the recent
changes.
Before calling the SMP infrastructure, check if only a local TLB flush
is needed to restore the lost performance in this common case. This
requires to check mm_cpumask() one more time, but unless this mask is
updated very frequently, this should impact performance negatively.

[PULL]: tip/cpus4096 updates
Hi Ingo,
Please pull a few more cpus4096 changes. Most are fairly lightweight with the
biggest change being to use cpumask_var_t's for the domain and pending_mask
cpumask's in irq_desc.
It also deals with this cpu_evtchn_mask bss space bump:
65536 +2031616 2097152 +3100% cpu_evtchn_mask(.bss)
Everything merges into tip/master cleanly.
Thanks!
Mike
