Move compat system call declarations to compat header file

2009-01-18T18:43:50+00:00

commit 4c696ba7982501d43dea11dbbaabd2aa8a19cc42 upstream. Move declarations to correct header file. Signed-off-by: Heiko Carstens Signed-off-by: Greg Kroah-Hartman

remove __ARCH_WANT_COMPAT_SYS_PTRACE

2008-11-30T19:00:15+00:00

All architectures now use the generic compat_sys_ptrace, as should every new architecture that needs 32bit compat (if we'll ever get another). Remove the now superflous __ARCH_WANT_COMPAT_SYS_PTRACE define, and also kill a comment about __ARCH_SYS_PTRACE that was added after __ARCH_SYS_PTRACE was already gone.

compat: generic compat get/settimeofday

2008-10-16T18:21:33+00:00

Nothing arch specific in get/settimeofday. The details of the timeval conversion varied a little from arch to arch, but all with the same results. Also add an extern declaration for sys_tz to linux/time.h because externs in .c files are fowned upon. I'll kill the externs in various other files in a sparate patch.

compat: move cp_compat_stat to common code

2008-10-16T18:21:33+00:00

struct stat / compat_stat is the same on all architectures, so cp_compat_stat should be, too. Turns out it is, except that various architectures have slightly and some high2lowuid/high2lowgid or the direct assignment instead of the SET_UID/SET_GID that expands to the correct one anyway. This patch replaces the arch-specific cp_compat_stat implementations with a common one based on the x86-64 one. Signed-off-by: Christoph Hellwig Acked-by: David S.

ntp: support for TAI

2008-05-01T15:03:59+00:00

This adds support for setting the TAI value (International Atomic Time). The value is reported back to userspace via timex (as we don't have a ntp_gettime() syscall). Signed-off-by: Roman Zippel Cc: john stultz Cc: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

timerfd: new timerfd API

2008-02-05T17:44:07+00:00

This is the new timerfd API as it is implemented by the following patch: int timerfd_create(int clockid, int flags); int timerfd_settime(int ufd, int flags, const struct itimerspec *utmr, struct itimerspec *otmr); int timerfd_gettime(int ufd, struct itimerspec *otmr); The timerfd_create() API creates an un-programmed timerfd fd. The "clockid" parameter can be either CLOCK_MONOTONIC or CLOCK_REALTIME. The timerfd_settime() API give new settings by the timerfd fd, by optionally retrieving the previous expiration time (in case the "otmr" parameter is not NULL). The time value specified in "utmr" is absolute, if the TFD_TIMER_ABSTIME bit is set in the "flags" parameter. Otherwise it's a relative time. The timerfd_gettime() API returns the next expiration time of the timer, or {0, 0} if the timerfd has not been set yet. Like the previous timerfd API implementation, read(2) and poll(2) are supported (with the same interface). Here's a simple test program I used to exercise the new timerfd APIs: http://www.xmailserver.org/timerfd-test2.c [akpm@linux-foundation.org: coding-style cleanups] [akpm@linux-foundation.org: fix ia64 build] [akpm@linux-foundation.org: fix m68k build] [akpm@linux-foundation.org: fix mips build] [akpm@linux-foundation.org: fix alpha, arm, blackfin, cris, m68k, s390, sparc and sparc64 builds] [heiko.carstens@de.ibm.com: fix s390] [akpm@linux-foundation.org: fix powerpc build] [akpm@linux-foundation.org: fix sparc64 more] Signed-off-by: Davide Libenzi Cc: Michael Kerrisk Cc: Thomas Gleixner Cc: Davide Libenzi Cc: Michael Kerrisk Cc: Martin Schwidefsky Signed-off-by: Heiko Carstens Cc: Michael Kerrisk Cc: Davide Libenzi Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

x86: compat_sys_ptrace

2008-01-30T12:31:48+00:00

This adds a generic definition of compat_sys_ptrace that calls compat_arch_ptrace, parallel to sys_ptrace/arch_ptrace. Some machines needing this already define a function by that name. The new generic function is defined only on machines that put #define __ARCH_WANT_COMPAT_SYS_PTRACE into asm/ptrace.h.

x86: compat_ptrace_request

2008-01-30T12:31:47+00:00

This adds a compat_ptrace_request that is the analogue of ptrace_request for the things that 32-on-64 ptrace implementations can share in common. So far there are just a couple of requests handled generically. Signed-off-by: Roland McGrath Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner
