2007-05-21Blackfin arch: fix signal handling bugBernd Schmidt
There's a forum thread at https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&_forum_action=MessageReply&message_id=24741 which has a testcase involving signal handling that crashes quite readily. Inspecting the code I believe what happens is that signal handling can become confused when it is invoked on return from an interrupt, if the contents of P0 and R0 at the time of the interrupt happen to be such that P0 is larger than zero (indicating to the signal code that we're in a syscall), and R0 happens to have a value of something like -EINTR or -ERESTARTSYS. Fixed by setting orig_p0 to -1 if we're returning from an interrupt. The testcase now seems to run without problems.

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%). Cross-compile tested on all arm defconfigs, all mips defconfigs, all powerpc defconfigs, alpha alpha-up arm i386 i386-up i386-defconfig i386-allnoconfig ia64 ia64-up m68k mips parisc parisc-up powerpc powerpc-up s390 s390-up sparc sparc-up sparc64 sparc64-up um-x86_64 x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig as well as my two usual configs.

2007-05-19[CRYPTO] api: Read module pointer before freeing algorithmHerbert Xu
The function crypto_mod_put first frees the algorithm and then drops the reference to its module. Unfortunately we read the module pointer which after freeing the algorithm and that pointer sits inside the object that we just freed. So this patch reads the module pointer out before we free the object. Thanks to Luca Tettamanti for reporting this. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2007-05-18cciss: Fix pci_driver.shutdown while device is still activeGerald Britton
Fix an Oops in the cciss driver caused by system shutdown while a filesystem on a cciss device is still active. The cciss_remove_one function only properly removes the device if the device has been cleanly released by its users, which is not the case when the pci_driver.shutdown method is called. This patch adds a new cciss_shutdown function to better match the pattern used by various SCSI drivers: deactivate device interrupts and flush caches. It also alters the cciss_remove_one function to match and readds the __devexit annotation that was removed when cciss_remove_one was serving as the pci_driver.shutdown method.

From the changelog: after this patch: ... delayed_work_timer_fn->__queue_work() in progress. The latter doesn't differ from the caller's POV, it does make a difference if the caller calls flush_workqueue() after cancel_delayed_work(), in that case flush_workqueue() can miss this work_struct.

2007-05-17Revert "[PATCH] x86: Drop cc-options call for all options supported in gcc 3.2+"Linus Torvalds
This reverts commit c8fdd247255a3a027cd9f66dcf93e6847d1d2f85. It turns out the kernel was correct, and the gcc complaint was a gcc bug. The preferred stack boundary is expressed not in bytes, but in the the log2() of the preferred boundary, so "-mpreferred-stack-boundary=2" is in fact exactly what we want, but a gcc that is compiled for x86-64 will consider it an error (because the 64-bit calling sequence says that the stack should be 16-byte aligned) even if we are then using "-m32" to generate 32-bit code.
