-next code
Changes in v2:
* Removed patch to implement slow_virt_to_phys() on ARM64.
Use of slow_virt_to_phys() in arch independent Hyper-V
drivers has been eliminated by commit 6ba34171bcbd
("Drivers: hv: vmbus: Remove use of slow_virt_to_phys()")
* Minor tweaks to rebase to latest
This code is architecture dependent code and is mostly driven by
architecture independent code in the VMbus driver in drivers/hv/hv.c
and drivers/hv/vmbus_drv.c.
This code is built only when CONFIG_HYPERV is enabled.

MAINTAINERS
Add slow_virt_to_phys() function for ARM64 that parallels the same
function on x86/x64. This is needed by the architecture independent
Hyper-V VMbus driver at drivers/hv/channel.c. The implementation
directly translates the virtual address using the ARM64 'at'
instruction.
Signed-off-b
hing more
generic, so the code uses the Hyper-V terminology. This will be
fixed when Hyper-V updates the usage in the TLFS.
Michael Kelley (5):
arm64: mm: Add slow_virt_to_phys()
arm64: hyperv: Add core Hyper-V include files
arm64: hyperv: Add support for Hyper-V as a hypervisor
Drivers:
This code is architecture dependent code and is mostly driven by
architecture independent code in the VMbus driver in drivers/hv/hv.c
and drivers/hv/vmbus_drv.c.
This code is built only when CONFIG_HYPERV is enabled.

MAINTA
Add direct #include statements for declarations of csum_tcpudp_magic()
and csum_ipv6_magic(). While the needed #include's are picked up
indirectly for the x86 architecture, they aren't on other
architectures, resulting in compile errors.

Changes in v2:
* Restructured to do signaling calcuations only if needed. Makes
the most common path faster [KY Srinivasan, Steve Hemminger]
* Moved bytes read calculation to new routine hv_pk
/x64 don't use an IRQ.

I'm really concerned about defining the Hyper-V function to flush
guest mappings in terms of a KVM struct definition. Your patch puts
this function in arch/x

Hopefully asm/kvm_host.h does not need to be #included, given
the new code structure.
