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:

The timerfd was using the unlocked waitqueue operations, but it was using a different lock, so poll_wait() would race with it. This makes timerfd directly use the waitqueue lock. Signed-off-by:

As pointed out by Jarek Poplawski, the patch [WORKQUEUE]: cancel_delayed_work: use del_timer() instead of del_timer_sync() commit: 071b6386 was wrong, it was merged by mistake after that. 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.

This reverts commit c8fdd247. 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.

With STANDBYDOWN tracking added, libata.spindown_compat isn't necessary anymore. If userspace shutdown(8) issues STANDBYNOW, libata warns. If userspace shutdown(8) doesn't issue STANDBYNOW, libata does the right thing. Userspace can tell whether kernel supports spindown by testing whether sysfs node manage_start_stop exists as before.

As with all other drivers, sata_nv's hpriv is allocated with devm_kzalloc() and there's no need to free it explicitly. Kill nv_remove_one() which incorrectly used kfree() instead of devm_kfree() and use ata_pci_remove_one() directly. Original fix is from Peer Chen. Signed-off-by:

Because nvidia SATA controllers onward base on AHCI, so wildcard in sata_nv driver is unnecessary. Also the wildcard sometimes cause sata_nv driver to be loaded for AHCI controllers,which is not as expected. Signed-off-by:
