Subject: [patch 1/8] s390: system calls.
Date: Thu, 17 Mar 2005 15:55:59 +0100 [thread overview]
Message-ID: <20050317145559.GA4807@mschwid3.boeblingen.de.ibm.com> (raw)
[patch 1/8] s390: system calls.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
s390 system call fixes:
- Add missing waitid and remap_file_pages system calls to s390.
- Keep consistent naming scheme xxx_wrapper in compat_wrapper.S.
- Remove #undef of __NR_getdents64 for 64 bit. The system call is
present for 64 bit (linux_getdents and linux_getdents64 differ).
