[PATCH v3] ubsan: Avoid unnecessary 128-bit shifts

If CONFIG_ARCH_SUPPORTS_INT128, s_max is 128 bits, and variable sign-extending shifts of such a double-word data type are a non-trivial amount of code and complexity. Do a single-word sign-extension *before* the cast to (s_max), greatly simplifying the object code. Rasmus Villemoes suggested usin

The Linux guest page size and hypervisor page size concepts are different, even though they happen to be the same value on x86. Hyper-V code mixes up the two, so this patchset begins to address that by creating and using a set of Hyper-V specific page definitions. A major benefit of those new defi
