[PATCH 0/5] x86/entry: Break up common.c

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.

This is code reorganization only, no functional changes.

Brian Gerst (5):
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()
