[Xen-devel] [PATCH v3 00/15] xen: arm: 64-bit dom0 kernel support
Initially we intended this to go into 4.3 but it didn't make it, so here
it is rebased onto current staging.
Other than the rebasing the only significant change is a major howler in
the entry.S code -- we weren't restoring any of the outer stack frame
guest state for 32- or 64-bit guests! Most of the 32-bit guest state is
in the inner frame and the outer frame contains "only" the SPSR_*
registers. Amazing how far you can get without context switching those!
For a 64-bit guest the outer frame includes ELR_el1, so the SMC trap
injection code exposed the problem...
Ian.
