Revision 9f1ee7b169afbd10c3ad254220d1b37beb5798aa authored by Paolo Bonzini on 18 October 2021, 10:49:18 UTC, committed by Paolo Bonzini on 18 October 2021, 18:07:19 UTC
The size of the GHCB scratch area is limited to 16 KiB (GHCB_SCRATCH_AREA_LIMIT),
so there is no need for it to be a u64. This fixes a build error on 32-bit
systems:
i686-linux-gnu-ld: arch/x86/kvm/svm/sev.o: in function `sev_es_string_io:
sev.c:(.text+0x110f): undefined reference to `__udivdi3'
Cc: stable@vger.kernel.org
Fixes: 019057bd73d1 ("KVM: SEV-ES: fix length of string I/O")
