    Pull x86 fixes from Borislav Petkov:

     - Fix a couple of SWAPGS fencing issues in the x86 entry code

     - Use the proper operand types in __{get,put}_user() to prevent
       truncation in SEV-ES string io

     - Make sure the kernel mappings are present in trampoline_pgd in order
       to prevent any potential accesses to unmapped memory after switching
       to it

     - Fix a trivial list corruption in objtool's pv_ops validation

     - Disable the clocksource watchdog for TSC on platforms which claim
       that the TSC is constant, doesn't stop in sleep states, CPU has TSC
       adjust and the number of sockets of the platform are max 2, to
       prevent erroneous markings of the TSC as unstable.

     - Make sure TSC adjust is always checked not only when going idle

     - Prevent a stack leak by initializing struct _fpx_sw_bytes properly in
       the FPU code

     - Fix INTEL_FAM6_RAPTORLAKE define naming to adhere to the convention
