Pull x86 fixes from Dave Hansen:
 "This is a pretty scattered set of fixes. The majority of them are
  further fixups around the recent ITS mitigations.

  The rest don't really have a coherent story:

   - Some flavors of Xen PV guests don't support large pages, but the
     set_memory.c code assumes all CPUs support them.

     Avoid problems with a quick CPU feature check.

   - The TDX code has some wrappers to help retry calls to the TDX
     module. They use function pointers to assembly functions and the
     compiler usually generates direct CALLs. But some new compilers,
     plus -Os turned them in to indirect CALLs and the assembly code was
     not annotated for indirect calls.

     Force inlining of the helper to fix it up.

   - Last, a FRED issue showed up when single-stepping. It's fine when
     using an external debugger, but was getting stuck returning from a
     SIGTRAP handler otherwise.

     Clear the FRED 'swevent' bit to ensure that forward progress is
     made"
