[PATCH] powerpc/hvcall: Reorder Nestedv2 hcall opcodes

Tue Dec 19 20:22:36 AEDT 2023


This trivial patch reorders the newly introduced hcall opcodes for Nestedv2
to follow the increasing-opcode-number convention followed in
'hvcall.h'. The patch also updates the value for MAX_HCALL_OPCODE which is
at various places in arch code for range checking.

Fixes: 19d31c5f1157 ("KVM: PPC: Add support for nestedv2 guests")
