Li Fei1 1db32f4d03 hv: ept: build 4KB page mapping in EPT for code pages of rtvm ... RTVM is enforced to use 4KB pages to mitigate CVE-2018-12207 and performance jitter, which may be introduced by splitting large page into 4KB pages on demand. It works fine in previous hardware platform where the size of address space for the RTVM is relatively small. However, this is a problem when the platforms support 64 bits high MMIO space, which could be super large and therefore consumes large # of EPT page table pages. This patch optimize it by using large page for purely data pages, such as MMIO spaces, even for the RTVM. Signed-off-by: Li Fei1 <fei1.li@intel.com> Tracked-On: #5788		2021-03-03 13:46:49 +08:00
