From: James Hogan Date: Fri, 8 May 2015 16:11:49 +0000 (+0100) Subject: KVM: MIPS: Claim KVM_CAP_READONLY_MEM support X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=230c57244c2c4d945dba7f9d15845bffe4135b58;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git KVM: MIPS: Claim KVM_CAP_READONLY_MEM support Now that load/store faults due to read only memory regions are treated as MMIO accesses it is safe to claim support for read only memory regions (KVM_CAP_READONLY_MEM).
