headers_install by default puts headers into usr/include/ . They're auto-generated, so should be ignored. Same for *.orig, *.rej . Signed-off-by:

kernel/printk.c: document possible deadlock against scheduler The printk's comment states that it can be called from every context, which might lead to false illusion that it could be called from everywhere without any restrictions. This is however not true - a call to printk() could deadlock if called from scheduler code (namely from schedule(), wake_up(), etc) on runqueue lock when it tries to wake up klogd. Document this.

We've been using the 'new locking' for a long time now so it seems pointless keeping the old one around. Remove it and undo the macros it uses back into real code for readability. Remove the bogus 'no termios change' checks. Signed-off-by:

Alan Cox authored
Lots of serial drivers check and optimise for setting the termios values to the ones they were before. This is pointless and the check is wrong anyway. Remove the checks on the serial drivers. If we ever do need such a check put it back in the tty layer instead _once_! Signed-off-by:

Now we always use stop_machine for module insertion or deletion, we no longer need the modlist_lock: merely disabling preemption is sufficient to block against list manipulation. This avoids deadlock on OOPSen where we can potentially grab the lock twice. Bug: 8695 Signed-off-by:

Change cancel_work_sync() and cancel_delayed_work_sync() to return a boolean indicating whether the work was actually cancelled. A zero return value means that the work was not pending/queued. Without that kind of change it is not possible to avoid flush_workqueue() sometimes, see the next patch as an example. Also, this patch unifies both functions and kills the (unlikely) busy-wait loop.

Imho, the current naming of cancel_xxx workqueue functions is very confusing. cancel_delayed_work() cancel_rearming_delayed_work() cancel_rearming_delayed_workqueue() // obsolete cancel_work_sync() This looks as if the first 2 functions differ in "type" of their argument which is not true any longer, nowadays the difference is the behaviour. The semantics of cancel_rearming_delayed_work(dwork) was changed significantly, it doesn't require that dwork rearms itself, and cancels dwork synchronously. Rename it to cancel_delayed_work_sync(). This matches cancel_delayed_work() and cancel_work_sync(). Re-create cancel_rearming_delayed_work() as a simple inline obsolete wrapper, like cancel_rearming_delayed_workqueue(). Signed-off-by:

The UMSDOS filesystem was removed back in 2.6.11, but some tiny bits stuck around. This patch removes the few remaining leftovers. The only things left behind after this are the entries in the CREDITS file and the ioctl number in Documentation/ioctl-number.txt as documentation. This third (hopefully final) version of the patch doesn't edit the arch/um/config.release file, since Jeff Dike pointed out to me that it should die completely, and asked me to remove it from my patch as he'll send in a seperate patch removing the file completely.

The current generic bug implementation has a call to dump_stack() in case a WARN_ON(whatever) gets hit. Since report_bug(), which calls dump_stack(), gets called from an exception handler we can do better: just pass the pt_regs structure to report_bug() and pass it to show_regs() in case of a warning. This will give more debug informations like register contents, etc... In addition this avoids some pointless lines that dump_stack() emits, since it includes a stack backtrace of the exception handler which is of no interest in case of a warning. E.g. on s390 the following lines are currently always present in a stack backtrace if dump_stack() gets called from report_bug(): [<000000000001517a>] show_trace+0x92/0xe8) [<0000000000015270>] show_stack+0xa0/0xd0 [<00000000000152ce>] dump_stack+0x2e/0x3c [<0000000000195450>] report_bug+0x98/0xf8 [<0000000000016cc8>] illegal_op+0x1fc/0x21c [<00000000000227d6>] sysc_return+0x0/0x10 Acked-by:

The IO port range requested by parport_pc.c:sio_ite_8872_probe is too small. The IO-ports of ttyS1 (0x2f8) will be missconfigured by the ITE-chip. The ITE starts looking for the chip a 0x2a0. An IO-portrange of 32 will not overwrite the ports of ttyS1. Therefore register 0x60 should be written with 0xe5000000, enabling the ITE and setting IO-portsize to 32 bytes. Signed-off-by:

This follows a suggestion from Chuck Ebbert on how to make seccomp absolutely zerocost in schedule too. The only remaining footprint of seccomp is in terms of the bzImage size that becomes a few bytes (perhaps even a few kbytes) larger, measure it if you care in the embedded. Signed-off-by:

This reduces the memory footprint and it enforces that only the current task can enable seccomp on itself (this is a requirement for a strightforward [modulo preempt ;) ] TIF_NOTSC implementation). Signed-off-by:

The HFS+ filesystem is case-insensitive and does automatic unicode decomposition by default, but does not provide custom dentry operations. This can lead to multiple dentries being cached for lookups on a filename with varying case and/or character (de)composition. These patches add custom dentry hash and comparison operations for case-sensitive and/or automatically decomposing HFS+ filesystems. Unicode decomposition and case-folding are performed as required to ensure equivalent filenames are hashed to the same values and compare as equal. This patch: Refactor existing HFS+ ASCII to unicode string conversion routine to split out character conversion functionality. This will be reused by the custom dentry hash and comparison routines. This approach avoids unnecessary memory allocation compared to using the string conversion routine directly in the new functions.
