Hello,
Following series contain some fixes for cache control operations, the
main focus is to reduce the load on big systems when cache control
operations are executed.
Patches 1-4 are bugfixes, while patches starting from 5 are improvements
to the current code. Patch 9 is an optimization to avoid having to
broadcast cache flushes on all pCPUs on x86.
Thanks, Roger.
Roger Pau Monne (9):
x86/pv: fix MMUEXT_FLUSH_CACHE to flush all pCPU caches
x86/pv: fix emulation of wb{,no}invd to flush all pCPU caches
xen/gnttab: limit cache flush operation to guests allowed cache
control
x86/gnttab: do not implement GNTTABOP_cache_flush
x86/mtrr: use memory_type_changed() in hvm_set_mem_pinned_cacheattr()
x86/p2m: limit cache flush in memory_type_changed()
xen/x86: rename cache_flush_permitted() to has_arch_io_resources()
xen: introduce flag when a domain requires cache control
xen/x86: track dirty pCPU caches for a given vCPU
