[PATCH v8 3/3] target/arm/kvm: Report memory errors injection

[“William Roche <william.roche@xxxxxxxxxx>]

From: William Roche <william.roche@xxxxxxxxxx>

Generate an x86 similar error injection message on ras enabled ARM
platforms.
ARM qemu only deals with action required memory errors signaled with
SIGBUS/BUS_MCEERR_AR, and will report a message on every memory error
relayed to the VM. A message like:
Guest Memory Error at QEMU addr 0xXXX and GUEST addr 0xYYY of type BUS_MCEERR_AR injected
