ARM: kvm: rename cpu_reset to avoid name clash

2013-09-24T18:15:05+00:00

cpu_reset is already #defined in  as processor.reset,
so it expands here and causes problems.

Pull ARM updates from Russell King:
 "This set includes adding support for Neon acceleration of RAID6 XOR
  code from Ard Biesheuvel, cache flushing and barrier updates from Will
  Deacon, and a cleanup to the ARM debug code which reduces the amount
  of code by about 500 lines.

  A few other cleanups, such as constifying the machine descriptors
  which already shouldn't be written to, cleaning up the printing of the
  L2 cache size"

Pull KVM updates from Gleb Natapov:
 "The highlights of the release are nested EPT and pv-ticketlocks
  support (hypervisor part, guest part, which is most of the code, goes
  through tip tree).  Apart of that there are many fixes for all arches"

ARM: KVM: Add newlines to panic strings

2013-08-30T22:48:02+00:00

The panic strings are hard to read and on narrow terminals some
characters are simply truncated off the panic message.

Make is slightly prettier with a newline in the Hyp panic strings.

ARM: KVM: Work around older compiler bug

2013-08-30T22:47:58+00:00

Compilers before 4.6 do not behave well with unnamed fields in structure
initializers and therefore produces build errors:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676

By refering to the unnamed union using braces, both older and newer
compilers produce the same result.

ARM: 7808/1: KVM: mm: Get rid of L_PTE_USER ref from PAGE_S2_DEVICE

2013-08-13T19:25:06+00:00

THe L_PTE_USER actually has nothing to do with stage 2 mappings and the
L_PTE_S2_RDWR value sets the readable bit, which was what L_PTE_USER
was used for before proper handling of stage 2 memory defines.

Changelog:
  [v3]: Drop call to kvm_set_s2pte_writable in mmu.c
  [v2]: Change default mappings to be r/w instead of r/o, as per Marc
     Zyngier's suggestion.

ARM: kvm: use inner-shareable barriers after TLB flushing

2013-08-12T11:25:45+00:00

When flushing the TLB at PL2 in response to remapping at stage-2 or VMID
rollover, we have a dsb instruction to ensure completion of the command
before continuing.

Since we only care about other processors for TLB invalidation, use the
inner-shareable variant of the dsb instruction instead.

KVM: ARM: Squash len warning

2013-08-12T04:03:39+00:00

The 'len' variable was declared an unsigned and then checked for less
than 0, which results in warnings on some compilers.  Since len is
assigned an int, make it an int.
