install_ept_entry would overwrite arbitrary memory when it encountered a large page. I discovered the bug while working on a simple multi-page allocator, which I'm using for huge page testing, that sorts the free list in ascending order of HPA. v3: * Added #define BITS_PER_LONG_LONG 64 * Fixed EPT_ADDR_MASK bit range * Made EPT_ADDR_MASK unsigned long long v2: * Added lib/bitops.h for GENMASK. * Factored common stuff out of lib/*/asm/bitops.h * Fixed all of the whitespace in vmx.h.
