[PATCH v3 0/2] CALL_NOSPEC fixes

[Pawan Gupta]

v3:
- Split the CS prefix change into a separate patch. (Ingo)

v2: https://lore.kernel.org/r/20250227-call-nospec-v2-1-895a30dceaac@xxxxxxxxxxxxxxx
- Fixed the inconsistency in the use of "\" in __CS_PREFIX. (Andrew)
- Fixed the comment to reflect that __CS_PREFIX only emits the prefix and
  not the JMP/CALL. (Andrew)

v1: https://lore.kernel.org/r/20250226-call-nospec-v1-1-4dde04a5c7a7@xxxxxxxxxxxxxxx

Patch 1 simplifies CALL_NOSPEC and mimics the behavior of compiler induced
thunks.

Patch 2	adds a missing CS prefix in CALL_NOSPEC for inline asm.
