[PATCH] x86/kvm: Include linux/types.h in asm/kvm_para.h

From: WEI-HONG, YE

Date: Tue May 05 2026 - 03:09:44 EST


arch/x86/include/asm/kvm_para.h uses u32 in function declarations, but
does not include linux/types.h itself. One user, mtrr.c, carried an
explicit workaround for this dependency.

Include linux/types.h from asm/kvm_para.h and remove the workaround from
mtrr.c.

Build-tested with x86_64 defconfig.
