gcc doesn't understand that "asmlinkage" routines have the argument stack owned by the assembly-language caller, and the recent sparse cleanup made gcc think it owns enough stack frame space to make a tailcall by overwriting "struct pt_regs" that is set up by the low-level system call code. Hide that problem again. The real fix would be to tell gcc that the caller owns the stack frame that it set up, but we don't have any such interfaces, so for now the best we can do is to hide it.

After Andi's timestamp optimizations we don't have any timestamps on the packets unless someone requested them. Here's a patch for 2.6 to explicitly timestamp the packets before we log them. Harald approved it some time ago, he's pretty busy so I'm sending it instead. Signed-off-by:

The patch below (already ACK'ed by Randy Dunlap) kills the unused IKCONFIG_VERSION from kernel/configs.c . This patch is based on a previous patch by Anton Blanchard and an idea of Bartlomiej Zolnierkiewicz. (I hope I haven't forgotten anyone who contributed to this patch. ;-) ) Signed-off-by:

CONFIG_H8 in drivers/char/ depends in both 2.4 and 2.6 on CONFIG_OBSOLETE which is never enabled. To remove this driver, the following is required additionally to the patch below: rm drivers/char/h8.c rm drivers/char/h8.h This patch was already ACK'ed by Richard Henderson. Signed-off-by:

The patch below solves Bugzilla #3014 by removing much outdated information from the ext2 help text. The help text is now very short, but few correct information is better than outdated information - and if you think it's too short, feel free to send a patch that adds more current information.

[PATCH] s390: cpu hotplug bugs. From: Ursula Braun-Krahl <braunu@de.ibm.com> From: Martin Schwidefsky <schwidefsky@de.ibm.com> iucv driver changes: - Fix iucv declare/retrieve buffer which the cpu hotplug patch has broken. - Make smp_call_function_on call func(info) in non-smp kernels. - Use a spinlock to get smp_get_cpu/smp_put_cpu race free.

From: Martin Schwidefsky <schwidefsky@de.ibm.com> From: Ulrich Weigand <uweigand@de.ibm.com> s390 core changes: - Add signo between signal frame and the signal return instruction on the user stack for backtrace over signal handlers. - Add hfp floating point exceptions. - Use a single function for region, segment and page translation exceptions. - Discard SIGTRAP for single stepped instructions if the trapping instruction is repeated (normal memory faults) or if another signal is delivered anyway.

I believe reading the i_size from memory multiple times can generate fs corruption. The "offset" and the "end_index" were not coherent. this is writepages and it runs w/o the i_sem, so the i_size can change from under us anytime. If a parallel write happens while writepages run, the i_size could advance from 4095 to 4100. With the current 2.6 code that could translate in end_index = 0 and offset = 4. That's broken because end_index and offset could be not coherent. Either end_index=1 and offset =4, or end_index = 0 and offset = 4095. When they lose coherency the memset can zeroout actual data. The below patch fixes that (it's at least a theoretical bug). I don't really expect this tiny race to fix the bug in practice after the more serious bugs we covered yesterday didn't fix it (more likely the compiler will get involved into the equation soon ;). This is also an optimization for 32bit archs that needs special locking to read 64bit i_size coherenty. This patch also arranges for mpage_writepages() to always zero out the file's final page between i_size and the end of the file's final block. This is a best-effort correctness thing to deal with errant applications which write into the mmapped page beyond the underlying file's EOF. Signed-off-by:

Fix a data loss bug in mpage_writepages(), triggerable under extreme memory pressure on ext2, JFS, hfs and hfsplus: The bug is the marking of the bh clean despite we could still run into the "confused" path. After that the confused path really becomes confused and it writes nothing and fs corruption triggers silenty (the reugular writepage only writes bh that are marked dirty, it never attempts to submit_bh anything marked clean). The mpage-writepage code must never mark the bh clean as far as it wants to still fallback in the regular writepage which depends on the bh to be dirty (i.e. the "goto confused" path). This could only triggers with memory pressure (it also needs buffer_heads_over_limit == 0, and that is frequent under mm pressure). Thanks a lot to Chris for his fine debugging that localized the problem in the writepage code. Signed-off-by:

Nick has tracked scheduling-while-atomic errors to shmem's fragile kmap avoidance: the root error appears to lie deeper, but rework that fragility. Plus I've been indicted for war crimes at the end of shmem_swp_entry: my apologia scorned, so now hide the evidence. Signed-off-by:

As pointed by Thomas Sailer, crc16.c module contains CRC16-CCITT (x^16 + x^12 + x^5 + 1) implementation, not IBM CRC16 (x^16 + x^15 + x^2 + 1) one. Looks like we need to rename it accordingly and this patchset does exactly this. Signed-off-by:
