[PATCH v4 00/14] ARM/ARM64: KVM: big endian host support

[victor.kamensky@linaro.org (Victor Kamensky)]

Hi Christoffer, Marc,

Could you please look at updated ARM BE KVM series. We worked
separately on specific patches, I believe now they should look
OK.

Changes since previous V3 version of series [1]:

o Updated Review-by Acked-by tags where appropriate

o 'ARM: KVM: __kvm_vcpu_run function return result fix in BE case'
patch changed __ARMEB__ to CONFIG_CPU_ENDIAN_BE8 as Marc suggested

o 'ARM: KVM: one_reg coproc set and get BE fixes' patch was 
siginificantly reworked based on separate thread discussion with
Christoffer - In short summry now we fix only oddball places where
reg_[from|to]_user function is used in case target variable 
mismatching register size

o 'ARM64: KVM: fix vgic_bitmap_get_reg function for BE 64bit case'
incorporated Christoffer's review comments about code comments
(spelling, grammar, etc)

o 'ARM64: KVM: set and get of sys registers in BE case' changed
patch siginificantly based on separate email thread feedback from
Christoffer and Marc - now patch just removes comment about
reg_[to|form]_user being little endian, since it handles only
64 bit register size current code is endian agnostic.

o 'ARM64: KVM: fix big endian issue in access_vm_reg for 32bit guest'
incorporoated Christoffer's review comments - two macros 
vcpu_cp15_64_high and vcpu_cp15_64_low now introduced which
defined differently between BE and LE cases

Series were tested on top of v3.15. On V7 4 combinations, BE/LE 
host x BE/LE guest, were tested with TC2. On V8 8 combinations,
BE/LE host x BE/LE guest x 32/64 bit guest, were tested on
Fast models.

Thanks,
Victor
