Subject: [PATCH v2 0/7] x86/entry: Break up common.c
Date: Fri, 14 Mar 2025 11:12:13 -0400	[thread overview]
Message-ID: <20250314151220.862768-1-brgerst@gmail.com> (raw)

The syscall dispatch code originally was put into entry/common.c so that
common code for entry from and exit to userspace could be inlined.  That
entry code has since been moved to the core kernel.  There is no longer
a need to keep this code together, so move it to more appropriate
places.

No functional changes.

Changes in v2:
- Move Xen inlines to enlighten_pv.c (Juergen Gross)
- Don't copy comments on the code's origins.  Git history has that
  information already (Sohil Mehta)
- Added cleanup patches (Sohil Mehta)

Brian Gerst (7):
  x86/xen: Move Xen upcall handler
  x86/syscall/32: Move 32-bit syscall dispatch code
  x86/syscall/64: Move 64-bit syscall dispatch code
  x86/syscall/x32: Move x32 syscall table
  x86/syscall: Move sys_ni_syscall()
  x86/syscall: Remove stray semicolons
  x86/syscall/32: Add comment to conditional
