Interesting. I just munged the old pre-merge
arch/x86/kernel/syscall_table_32.S
and the new
arch/x86/syscalls/syscall_32.tbl
with some trivial shell scripting, and they are definitely identical.
So the tables look like they match 1:1.
The compat tables match too, except the new list contains the entry for bdflush (134), but that's a legacy thing that doesn't matter.
I wonder what else could be going on. Wrong number of system calls check? Peter, any ideas?
