2011-05-19kmemleak: Initialise kmemleak after debug_objects_mem_init()Catalin Marinas
Kmemleak frees objects via RCU and when CONFIG_DEBUG_OBJECTS_RCU_HEAD is enabled, the RCU callback triggers a call to free_object() in lib/debugobjects.c. Since kmemleak is initialised before debug objects initialisation, it may result in a kernel panic during booting. This patch moves the kmemleak_init() call after debug_objects_mem_init().

2011-05-19kmemleak: Select DEBUG_FS unconditionally in DEBUG_KMEMLEAKCatalin Marinas
In the past DEBUG_FS used to depend on SYSFS and DEBUG_KMEMLEAK selected it conditionally. This is no longer the case, so always select DEBUG_FS via DEBUG_KMEMLEAK. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2011-05-19kmemleak: Do not return a pointer to an object that kmemleak did not getCatalin Marinas
The kmemleak_seq_next() function tries to get an object (and increment its use count) before returning it. If it could not get the last object during list traversal (because it may have been freed), the function should return NULL rather than a pointer to such object that it did not get.

2011-05-19m68k: bitops - Never step beyond the end of the bitmapGeert Uytterhoeven
find_next bitops on m68k (find_next_zero_bit, find_next_bit, and find_next_bit_le) may cause out of bounds memory access when the bitmap size in bits % 32 != 0 and offset (the bitnumber to start searching at) is very close to the bitmap size. For example, unsigned long bitmap[2] = { 0, 0 }; find_next_bit(bitmap, 63, 62); 1. find_next_bit() tries to find any set bits in bitmap[1], but no bits set. 2. Then find_first_bit(bimap + 2, -1) 3. Unfortunately find_first_bit() takes unsigned int as the size argument. 4. find_first_bit will access bitmap[2~] until it find any set bits. Add missing tests for stepping beyond the end of the bitmap to all find_{first,next}_*() functions, and make sure they never return a value larger than the bitmap size.

2011-05-19x86: Don't unmask disabled irqs when migrating themTian, Kevin
It doesn't make sense to unconditionally unmask a disabled irq when migrating it from offlined cpu to another. If the irq triggers then it will be disabled in the interrupt handler anyway.

We are generating the prefix based on the PCI bus address the device is on. This is done like Broadcom does it in their code expect that the the bus number is increased by one. In the SB bus implementation used by Broadcom the SB bus emulates a PCI bus so the kernel sees one PCI bus more then in our implementation. We do not handle prefixes like sb/1/ yet as they are only used on the new bus which is not implemented yet.

2011-05-19MIPS: BCM47xx: Extend bcm47xx_fill_sprom with prefix.Hauke Mehrtens
When an other SSB based device without an own SPROM is attached, using the PCI bus to the main SSB based device, the data normally found in the SPROM will be stored in the NVRAM on modern devices. The keys, to load the data from the NVRAM, are all using some sort of prefix like pci/1/1/, pci/1/3/ or sb/1/ before the actual key. This patch extends bcm47xx_fill_sprom() to make it possible to read out these values when some prefix was used. The keys for the SPROM data used on the main chip does not have a prefix.

2011-05-19SSB: Change fallback sprom to callback mechanism.Hauke Mehrtens
Some embedded devices like the Netgear WNDR3300 have two SSB based cards without an own sprom on the pci bus. We have to provide two different fallback sproms for these and this was not possible with the old solution. In the bcm47xx architecture the sprom data is stored in the nvram in the main flash storage. The architecture code will be able to fill the sprom with the stored data based on the bus where the device was found. The bcm63xx code should do the same thing as before, just using the new API.

2011-05-19MIPS: Alchemy: Clean up GPIO registers and accessorsManuel Lauss
remove au_readl/au_writel, remove the predefined GPIO1/2 KSEG1 register addresses and fix the fallout in all boards and drivers. This also fixes a bug in the mtx-1_wdt driver which was introduced by commit 6ea8115bb6f359df4f45152f2b40e1d4d1891392 ("Convert mtx1 wdt to be a platform device and use generic GPIO API") before this patch mtx-1_wdt only modified GPIO215, the patch then used the gpio resource information as bit index into the GPIO2 register but the conversion to the GPIO API didn't realize that. With this patch the drivers original behaviour is restored and GPIO15 is left alone.

2011-05-19MIPS: Alchemy: Cleanup DMA addressesManuel Lauss
According to the databooks, the Au1000 DMA engine must be programmed with the physical FIFO addresses. This patch does that; furthermore this opened the possibility to get rid of a lot of now unnecessary address defines.
