The Xtensa architecture also used dedicated syscalls and doesn't
need to multiplex ipc and socket subcalls.
* linux/syscall.h: Do not define SYS_socket_subcall and
SYS_ipc_subcall for xtensa.

The number of arguments spec
The number of arguments specified in syscallent.h does not include
registers that are skipped to align 64-bit arguments to even/odd
register pairs. So, always retrieve all registers used for arguments.
* syscall.c (get_syscall_args): always retrieve all syscall arguments

Hi,
Tested 6b03c9b5ced3d4f0d641443a73bd34ba481dbd1a for Xtensa. Builds fine
and runs some simple tests. However I found a couple of issues and have
sent patches to this list.
* We didn't retrieve enough registers from the kernel when we skip
registers to align 64-bit arguments to even/odd register

OK, you should know better. :)

Newer Linux architectures don't support the stat/stat64 syscalls.
Instead they use fstatat() with AT_FDCWD and an extra flags argument.
Support seeing this output in the 'strace -efile' test.
As part of this change, use "grep -E -x" syntax consistently for
all stat tests, since the number of \(foo

The tile arch just has the dedicated syscalls, so disable
the logic for parsing subcalls.

Newer Linux architectures don't support the stat/stat64 syscalls.
Instead they use fstatat() with AT_FDCWD and an extra flags argument.
Support seeing this output in the 'strace -efile' test.
