[PATCH 1/5] arm64: mm: Add slow_virt_to_phys()

2018-06-19 Thread Michael Kelley
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-by: Michael
