[PATCH v2] x86/mtrr: Drop stale linux/kvm_para.h include
From: WEI-HONG, YE
Date: Wed Jul 08 2026 - 09:58:02 EST
arch/x86/kernel/cpu/mtrr/mtrr.c includes linux/kvm_para.h for
historical reasons. The include was needed for kvm_para_available()
check in mtrr_trim_uncached_memory(), but that usage was removed by
commit bf3647c44bc7 ("x86: tone down mtrr_trim_uncached_memory()
warning").
Drop the stale linux/kvm_para.h include. This also removes the need for
explicit linux/types.h workaround that existed only because kvm_para.h
depended on it.

- Drop the stale linux/kvm_para.h include from mtrr.c instead of adding
linux/types to asm/kvm_para.h, as suggested by Sean.
