* [S390] No execute support cleanup.Martin Schwidefsky2007-04-27
| | | | | | | | | | Simplify the signal_return function that checks for the two special system calls sigreturn and rt_sigreturn. No need to do a page table walk, a call to copy_from_user while disabled page faults will work as well.

* [S390] Minor fault path optimization.Martin Schwidefsky2007-04-27
| | | | | | | | | | The minor fault path has grown a lot in terms of cycles. In particular the kprobes hook is very costly. Optimize the path to save a couple of cycles. If kprobes is enabled more than 300 cycles can be avoided if kprobes_running() is false.

* [S390] Use generic bug.Heiko Carstens2007-04-27
| | | | | | | | | | | | Generic bug implementation for s390. Will increase the value of the console output on BUG() statements since registers r0-r5,r14 will not be clobbered by a printk() call that was previously done before the illegal instruction of BUG() was hit. Also implements an architecture specific WARN_ON(). Output of that could be increased but requires common code change.

* [S390] Improved oops output.Martin Schwidefsky2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds two improvements to the oops output. First it adds an additional line after the PSW which decodes the different fields of it. Second a disassembler is added that decodes the instructions surrounding the faulting PSW. The output of a test oops now looks like this: kernel BUG at init/main.c:419 illegal operation: 0001 [#1] CPU: 0 Not tainted Process swapper (pid: 0, task: 0000000000464968, ksp: 00000000004be000) Krnl PSW : 0700000180000000 00000000000120b6 (rest_init+0x36/0x38) R:0 T:1 IO:1 EX:1 Key:0 M:0 W:0 P:0 AS:0 CC:0 PM:0 EA:3 Krnl GPRS: 0000000000000003 00000000004ba017 0000000000000022 0000000000000001 000000000003a5f6 0000000000000000 00000000004be6a8 0000000000000000 0000000000000000 00000000004b8200 0000000000003a50 0000000000008000 0000000000516368 000000000033d008 00000000000120b2 00000000004bdee0 Krnl Code: 00000000000120a6: e3e0f0980024 stg %r14,152(%r15) 00000000000120ac: c0e500014296 brasl %r14,3a5d8 00000000000120b2: a7f40001 brc 15,120b4 >00000000000120b6: 0707 bcr 0,%r7 00000000000120b8: eb7ff0500024 stmg %r7,%r15,80(%r15) 00000000000120be: c0d000195825 larl %r13,33d108 00000000000120c4: a7f13f00 tmll %r15,16128 00000000000120c8: a7840001 brc 8,120ca Call Trace: ([<00000000000120b2>] rest_init+0x32/0x38) [<00000000004be614>] start_kernel+0x37c/0x410 [<0000000000012020>] _ehead+0x20/0x80 Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a really rare and obscure bug in CFQ, that causes a crash in cfq_dispatch_insert() due to rq == NULL. One example of the resulting oops is seen here: http://lkml.org/lkml/2007/4/15/41 Neil correctly diagnosed the situation for how this can happen: if two concurrent requests with the exact same sector number (due to direct IO or aliasing between MD and the raw device access), the alias handling will add the request to the sortlist, but next_rq remains NULL. Read the more complete analysis at: http://lkml.org/lkml/2007/4/25/57 This looks like it requires md to trigger, even though it should potentially be possible to due with O_DIRECT (at least if you edit the kernel and doctor some of the unplug calls). The fix is to move the ->next_rq update to when we add a request to the rbtree. Then we remove the possibility for a request to exist in the rbtree code, but not have ->next_rq correctly updated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sis900 driver appears to have a bug in which the receive routine passes the skbuff holding the received frame to the network stack before refilling the buffer in the rx ring. If a new skbuff cannot be allocated, the driver simply leaves a hole in the rx ring, which causes the driver to stop receiving frames and become non-recoverable without an rmmod/insmod according to reporters. This patch reverses that order, attempting to allocate a replacement buffer first, and receiving the new frame only if one can be allocated. If no skbuff can be allocated, the current skbuf in the rx ring is recycled, dropping the current frame, but keeping the NIC operational.

But other places in the kernel still assume SSE and do FXSAVE and the CPU will then access FXSAVE information with FNSAVE and cause corruption. Easiest way to avoid this is to remove the option.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit ed8ccee0918ad063a4741c0656fda783e02df627. It causes hang on boot for some users and we don't yet know why: http://bugzilla.kernel.org/show_bug.cgi?id=7562 http://lkml.org/lkml/2007/4/20/404 http://lkml.org/lkml/2007/3/25/113 Just reverse it for 2.6.21-final, having broken X server is somehow better than unbootable system.

* | 8250: fix possible deadlock between serial8250_handle_port() and ↵Jiri Kosina2007-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | serial8250_interrupt() Commit 40b36daa introduced possibility that serial8250_backup_timeout() -> serial8250_handle_port() locks port.lock without disabling irqs, thus allowing deadlock against interrupt handler (port.lock is acquired in serial8250_interrupt()).
