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. Signed-off-by:

Blackfin arch: cache SWRST value at bootup so other things like watchdog can non-destructively query it Signed-off-by:

a) add new processor BF52x/BF54x header files b) update blackfin BF533/BF537/BF561 header files to latest one in VDSP. c) scrub watchdog/rtc masks from headers as we dont need/want them (too generic and the drivers dont use them) Signed-off-by:

Without conswitchp preset, we have the following situation: - During initcalls: con_init is called, and returns because of !display_desc. - At this point there is no memory allocated for vc_cons[].d A bit later vty_init calls kbd_init. - From now on events are passed to kbd_event which will then call kbd_keycode. - kbd_keycode will oops on a NULL pointer dereference on vc->vc_tty Signed-off-by:

1) Disable Interrupts during DMA memcpy to avoid raise conditions. 2) Mark MDMA channel 0 as reserved, since were using it internally. 3) Add DMA based equivalents for insX and outsX. 4) Our insX and outsX only handles len <= 2^16. Signed-off-by:

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.

* master.kernel.org:/pub/scm/linux/kernel/git/herbert/crypto-2.6: [CRYPTO] api: Read module pointer before freeing algorithm

Herbert Xu authored
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>

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. Signed-off-by:

A number of items in the i386 boot documentation have been either vague, outdated or hard to read. This text revision adds several more examples, including a memory map for a modern kernel load. It also adds a field-by-field detailed description of the setup header, and a bootloader ID for Qemu. Signed-off-by:

1 is a power of two, therefore roundup_pow_of_two(1) should return 1. It does in case the argument is a variable but in case it's a constant it behaves wrong and returns 0. Probably nobody ever did it so this was never noticed. Signed-off-by:
