Subject: [PATCH 4.19 045/131] kvm: fix compilation on aarch64
From: Paolo Bonzini <pbonzini@...hat.com>
commit c011d23ba046826ccf8c4a4a6c1d01c9ccaa1403 upstream.
Commit e45adf665a53 ("KVM: Introduce a new guest mapping API", 2019-01-31)
introduced a build failure on aarch64 defconfig:
$ make -j$(nproc) ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- O=out defconfig \
Image.gz
...
../arch/arm64/kvm/../../../virt/kvm/kvm_main.c:
In function '__kvm_map_gfn':
../arch/arm64/kvm/../../../virt/kvm/kvm_main.c:1763:9: error:
implicit declaration of function 'memremap'; did you mean 'memset_p'?
../arch/arm64/kvm/../../../virt/kvm/kvm_main.c:1763:46: error:
'MEMREMAP_WB' undeclared (first use in this function)
../arch/arm64/kvm/../../../virt/kvm/kvm_main.c:
In function 'kvm_vcpu_unmap':
../arch/arm64/kvm/../../../virt/kvm/kvm_main.c:1795:3: error:
implicit declaration of function 'memunmap'; did you mean 'vm_munmap'?
because these functions are declared in <linux/io.h> rather than <asm/io.h>,
and the former was being pulled in already on x86 but not on aarch64.
