RISC-V: KVM: Fix the size parameter check in SBI SFENCE calls
[ Upstream commit 6aba0cb5bba6141158d5449f2cf53187b7f755f9 ]
As-per the SBI specification, an SBI remote fence operation applies
to the entire address space if either:
1) start_addr and size are both 0
2) size is equal to 2^XLEN-1
>From the above, only #1 is checked by SBI SFENCE calls so fix the
size parameter check in SBI SFENCE calls to cover #2 as well.
Fixes: 13acfec2dbcc ("RISC-V: KVM: Add remote HFENCE functions based on VCPU requests")
