x86/entry: Switch page fault exception to IDTENTRY_RAW
Convert page fault exceptions to IDTENTRY_RAW:
- Implement the C entry point with DEFINE_IDTENTRY_RAW
- Add the CR2 read into the exception handler
- Add the idtentry_enter/exit_cond_rcu() invocations in
in the regular page fault handler and in the async PF
part.
- Emit the ASM stub with DECLARE_IDTENTRY_RAW
- Remove the ASM idtentry in 64-bit
- Remove the CR2 read from 64-bit
- Remove the open coded ASM entry code in 32-bit
- Fix up the XEN/PV code
- Remove the old prototypes
No functional change.
