* [SPARC]: Wire up sys_unshare().David S. Miller2006-02-07
| | | | | | | | Also, the Solaris syscall table is sized differrently, and does not go beyond entry 255, so trim off the excess entries. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC]: Add support for *at(), ppoll, and pselect syscalls.David S. Miller2006-01-19
| | | | | | | | | | This also includes by necessity _TIF_RESTORE_SIGMASK support, which actually resulted in a lot of cleanups. The sparc signal handling code is quite a mess and I should clean it up some day. Signed-off-by: David S. Miller <davem@davemloft.net>
* [PATCH] capable/capability.h (arch/)Randy Dunlap2006-01-11
| | | | | | | | arch: Use <linux/capability.h> where capable() is used. Signed-off-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [SPARC]: Kill CHILD_MAX.David S. Miller2005-12-23
| | | | | | | | | | | It's definition is wrong (-1 means "no limit" not 999), only the Sparc SunOS/Solaris compat code uses it, so let's just kill it off completely from limits.h and all referencing code. Noticed by Ulrich Drepper. Signed-off-by: David S. Miller <davem@davemloft.net>

* [PATCH] files: lock-free fd look-upDipankar Sarma2005-09-09
| | | | | | | | | | | | With the use of RCU in files structure, the look-up of files using fds can now be lock-free. The lookup is protected by rcu_read_lock()/rcu_read_unlock(). This patch changes the readers to use lock-free lookup.

* [PATCH] files-sparc64-fix 2Dipankar Sarma2005-09-09
| | | | | | | | | Fix sparc64 timod to use the new files_fdtable() api to get the fd table. This is necessary for RCUification. Signed-off-by: Dipankar Sarma <dipankar@in.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] files: break up files structDipankar Sarma2005-09-09
| | | | | | | | | | | | | | | In order for the RCU to work, the file table array, sets and their sizes must be updated atomically. Instead of ensuring this through too many memory barriers, we put the arrays and their sizes in a separate structure. This patch takes the first step of putting the file table elements in a separate structure fdtable that is embedded withing files_struct. It also changes all the users to refer to the file table using files_fdtable() macro. Subsequent applciation of RCU becomes easier after this.

* [SPARC64]: More fully work around Spitfire Errata 51.David S. Miller2005-08-29
| | | | | | | | | | | | It appears that a memory barrier soon after a mispredicted branch, not just in the delay slot, can cause the hang condition of this cpu errata. So move them out-of-line, and explicitly put them into a "branch always, predict taken" delay slot which should fully kill this problem. Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: Fix memory leak in sys_{send,recv}msg() w/compatAndrew Morton2005-08-09
| | | | | | | | | | | | | | | | | | | | | | | From: Dave Johnson <djohnson+linux-kernel@sw.starentnetworks.com> sendmsg()/recvmsg() syscalls from o32/n32 apps to a 64bit kernel will cause a kernel memory leak if iov_len > UIO_FASTIOV for each syscall! This is because both sys_sendmsg() and verify_compat_iovec() kmalloc a new iovec structure. Only the one from sys_sendmsg() is free'ed. I wrote a simple test program to confirm this after identifying the problem: http://davej.org/programs/testsendmsg.c Note that the below fix will break solaris_sendmsg()/solaris_recvmsg() as it also calls verify_compat_iovec() but expects it to malloc internally.

* [SPARC64]: Pass regs and entry/exit boolean to syscall_trace()David S. Miller2005-07-10
| | | | | | | | Also fix a bug in 32-bit syscall tracing. We forgot to update this code when we moved over to the convention that all 32-bit syscall arguments are zero extended by default. Signed-off-by: David S. Miller <davem@davemloft.net>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
