2016-01-07dmaengine: xgene-dma: Fix double IRQ issue by setting IRQ_DISABLE_UNLAZY flagRameshwar Prasad Sahu
For interrupt controller that doesn't support irq_disable and hardware with level interrupt, an extra interrupt can be pending. This patch fixes the issue by setting IRQ_DISABLE_UNLAZY flag for the interrupt line.

Pull MTD fixes from Brian Norris: "Three last MTD fixes for v4.4. These are all fixes for regressions and bugs reported mid cycle. Unfortunately, some of them took a bit long to get proper testing and feedback. - Assign the default MTD name earlier in the registration process, so partition parsers (like cmdlinepart) see the right name. Without this, some systems may come up with unpartitioned flash. This was a v4.4-rc1 regression. - Revert some new Winbond SPI NOR flash unlocking/locking support; new code in v4.4 caused regressions on some Spansion flash. - Fix mis-typed parameter ordering in SPI NOR unlock function; this bug was introduced in v4.4-rc1" * tag 'for-linus-20160106' of git://git.infradead.org/linux-mtd: mtd: spi-nor: fix stm_is_locked_sr() parameters mtd: spi-nor: fix Spansion regressions (aliased with Winbond) mtd: fix cmdlinepart parser, early naming for auto-filled MTD

commit d79f16c046086f4fe0d42184a458e187464eb83e fixed a user triggerable scribble on free memory but added a new one which allows the user to scribble even more and user controlled data into freed space.

2016-01-06irqchip/omap-intc: Add support for spurious irq handlingSekhar Nori
Under some conditions, irq sorting procedure used by INTC can go wrong resulting in a spurious irq getting reported.

2016-01-066pack: fix free memory scribblesOne Thousand Gnomes
commit acf673a3187edf72068ee2f92f4dc47d66baed47 fixed a user triggerable free memory scribble but in doing so replaced it with a different one that allows the user to control the data and scribble even more. sixpack_close is called by the tty layer in tty context. The tty context is protected by sp_get() and sp_put(). However network layer activity via sp_xmit() is not protected this way. We must therefore stop the queue otherwise the user gets to dump a buffer mostly of their choice into freed kernel pages. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: David S.

2016-01-06mtd: spi-nor: fix Spansion regressions (aliased with Winbond)Brian Norris
Spansion and Winbond have occasionally used the same manufacturer ID, and they don't support the same features. Particularly, writing SR=0 seems to break read access for Spansion's s25fl064k. Unfortunately, we don't currently have a way to differentiate these Spansion and Winbond parts, so rather than regressing support for these Spansion flash, let's drop the new Winbond lock/unlock support for now. We can try to address Winbond support during the next release cycle.

2016-01-04mtd: fix cmdlinepart parser, early naming for auto-filled MTDBrian Norris
Commit 807f16d4db95 ("mtd: core: set some defaults when dev.parent is set") attempted to provide some default settings for MTDs that (a) assign the parent device and (b) don't provide their own name or owner However, this isn't a perfect drop-in replacement for the boilerplate found in some drivers, because the MTD name is used by partition parsers like cmdlinepart, but the name isn't set until add_mtd_device(), after the parsing is completed. This means cmdlinepart sees a NULL name and therefore will not work properly. Fix this by moving the default name and owner assignment to be first in the MTD registration process. [Note: this does not fix all reported issues, particularly with NAND drivers. Will require an additional fix for drivers/mtd/nand/] Fixes: 807f16d4db95 ("mtd: core: set some defaults when dev.parent is set") Reported-by: Heiko Schocher <hs@denx.de> Signed-off-by: Brian Norris <computersforpeace@gmail.com> Cc: Heiko Schocher <hs@denx.de> Cc: Frans Klaver <fransklaver@gmail.com>
