2012-11-22md/raid10: decrement correct pending counter when writing to replacement.NeilBrown
When a write to a replacement device completes, we carefully and correctly found the rdev that the write actually went to and the blithely called rdev_dec_pending on the primary rdev, even if this write was to the replacement. This means that any writes to an array while a replacement was ongoing would cause the nr_pending count for the primary device to go negative, so it could never be removed. This bug has been present since replacement was introduced in 3.3, so it is suitable for any -stable kernel since then.

2012-11-22md/raid10: close race that lose writes lost when replacement completes.NeilBrown
When a replacement operation completes there is a small window when the original device is marked 'faulty' and the replacement still looks like a replacement. The faulty should be removed and the replacement moved in place very quickly, bit it isn't instant. So the code write out to the array must handle the possibility that the only working device for some slot in the replacement - but it doesn't. If the primary device is faulty it just gives up. This can lead to corruption. So make the code more robust: if either the primary or the replacement is present and working, write to them. Only when neither are present do we give up. This bug has been present since replacement was introduced in 3.3, so it is suitable for any -stable kernel since then.

2012-11-22IXP4xx: use __iomem for MMIOArnd Bergmann
The ixp4xx queue manager uses "const struct qmgr_regs __iomem *" as the type for a pointer that is passed to __raw_writel, which is not allowed because of the const-ness. Dropping the 'const' keyword fixes the problem. While we're here, let's also drop the useless type cast. Without this patch, building ixp4xx_defconfig results in: In file included from arch/arm/mach-ixp4xx/ixp4xx_qmgr.c:15:0: arch/arm/mach-ixp4xx/include/mach/qmgr.h: In function 'qmgr_put_entry': arch/arm/mach-ixp4xx/include/mach/qmgr.h:96:2: warning: passing argument 2 of '__raw_writel' discards 'const' qualifier from pointer target type [enabled by default] arch/arm/include/asm/io.h:88:91: note: expected 'volatile void *' but argument is of type 'const u32 *' In file included from drivers/net/ethernet/xscale/ixp4xx_eth.c:41:0: arch/arm/mach-ixp4xx/include/mach/qmgr.h: In function 'qmgr_put_entry': arch/arm/mach-ixp4xx/include/mach/qmgr.h:96:2: warning: passing argument 2 of '__raw_writel' discards 'const' qualifier from pointer target type [enabled by default] arch/arm/include/asm/io.h:88:91: note: expected 'volatile void *' but argument is of type 'const u32 *' arch/arm/mach-ixp4xx/ixp4xx_qmgr.c: In function 'qmgr_set_irq': arch/arm/mach-ixp4xx/ixp4xx_qmgr.c:41:9: warning: passing argument 2 of '__raw_writel' discards 'const' qualifier from pointer target type [enabled by default] arch/arm/include/asm/io.h:88:91: note: expected 'volatile void *' but argument is of type 'const u32 *' Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl>
