      ARM: dts: keystone: drop msmcsram clock node · 5a2abe19
      Ivan Khoronzhuk authored 
      

At late init all unused clocks are disabled. So clocks that were not
get before will be gated. In Keysone 2 SoC we have at least one
necessary clock that is not used by any driver - "msmcsram". This
clock is necessary, because it supplies the Multicore Shared Memory
Controller (MSMC). MSMC is the coherency interconnect and all the
coherent masters are connected to it including devices which are not
under Linux OS control. MSMC clock should not be touched even in low
power states.

So drop the clock node, otherwise 'clk_ignore_unused' parameter will
disable the clock leading to system stall.

      xen/pvh: Fix misplaced kfree from xlated_setup_gnttab_pages · f93576e1
      Dave Jones authored 
      

Passing a freed 'pages' to free_xenballooned_pages will end badly
on kernels with slub debug enabled.

This looks out of place between the rc assign and the check, but
we do want to kfree pages regardless of which path we take.

      xen/grant-table: Avoid m2p_override during mapping · 08ece5bb
      Zoltan Kiss authored 
      

The grant mapping API does m2p_override unnecessarily: only gntdev needs it,
for blkback and future netback patches it just cause a lock contention, as
those pages never go to userspace. Therefore this series does the following:
- the original functions were renamed to __gnttab_[un]map_refs, with a new
  parameter m2p_override
- based on m2p_override either they follow the original behaviour, or just set
  the private flag and call set_phys_to_machine
- gnttab_[un]map_refs are now a wrapper to call __gnttab_[un]map_refs with
  m2p_override false
- a new function gnttab_[un]map_refs_userspace provides the old behaviour

It also removes a stray space from page.h and change ret to 0 if
XENFEAT_auto_translated_physmap, as that is the only possible return value
there.

v2:
- move the storing of the old mfn in page->index to gnttab_map_refs
- move the function header update to a separate patch

v3:
- a new approach to retain old behaviour where it needed
- squash the patches into one

v4:
- move out the common bits from m2p* functions, and pass pfn/mfn as parameter
- clear page->private before doing anything with the page, so m2p_find_override
  won't race with this

v5:
- change return value handling in __gnttab_[un]map_refs
- remove a stray space in page.h
- add detail why ret = 0 now at some places

v6:
- don't pass pfn to m2p* functions, just get it locally
