Make sure we prepare/unprepare the clock for the COH901331 RTC driver as is required by the clk API especially if you use common clock. Signed-off-by:

Fix a case where users can try to allocate arbitarily large amounts of memory. 64K is overkill for a config request so apply an upper bound. Signed-off-by:

drivers/message/i2o/i2o_proc.c: the pointer returned from chtostr() points to an array which is no longer valid ... when being used in the calling function. Although it may work, the behavior is undefined. Detected by cppcheck. Signed-off-by:

There are two ways to create /sys/firmware/memmap/X sysfs: - firmware_map_add_early When the system starts, it is calledd from e820_reserve_resources() - firmware_map_add_hotplug When the memory is hot plugged, it is called from add_memory() But these functions are called without unifying value of end argument as below: - end argument of firmware_map_add_early() : start + size - 1 - end argument of firmware_map_add_hogplug() : start + size The patch unifies them to "start + size". Even if applying the patch, /sys/firmware/memmap/X/end file content does not change.

If there are two spinlocks embedded in a structure that kallsyms knows about and one of the spinlocks locks up we will print the name of the containing structure instead of the address of the lock. This is quite bad, so let's use %pS instead of %ps so we get an offset in addition to the symbol so we can determine which particular lock is having problems. Signed-off-by:

Convert ext4_count_free() to use memweight() instead of table lookup based counting clear bits implementation. This change only affects the code segments enabled by EXT4FS_DEBUG. Note that this memweight() call can't be replaced with a single bitmap_weight() call, although the pointer to the memory area is aligned to long-word boundary. Because the size of the memory area may not be a multiple of BITS_PER_LONG, then it returns wrong value on big-endian architecture. This also includes the following change. - Remove unnecessary map == NULL check in ext4_count_free() which always takes non-null pointer as the memory area. Signed-off-by:

memweight() is the function that counts the total number of bits set in memory area. Unlike bitmap_weight(), memweight() takes pointer and size in bytes to specify a memory area which does not need to be aligned to long-word boundary. [akpm@linux-foundation.org: rename `w' to `ret'] Signed-off-by:

There are many places in the kernel where the drivers print small buffers as a hex string. This patch adds a support of the variable width buffer to print it as a hex string with a delimiter. The idea came from Pavel Roskin here: http://www.digipedia.pl/usenet/thread/18835/17449/ Sample output of pr_info("buf[%d:%d] %*phC\n", from, len, len, &buf[from]); could be look like this: [ 0.726130] buf[51:8] e8:16:b6:ef:e3:74:45:6e [ 0.750736] buf[59:15] 31:81:b8:3f:35:49:06:ae:df:32:06:05:4a:af:55 [ 0.757602] buf[17:5] ac:16:d5:2c:ef Signed-off-by:

When using ALT+SysRq+Q all the pointers are replaced with "pK-error" like this: [23153.208033] .base: pK-error with echo h > /proc/sysrq-trigger it works: [23107.776363] .base: ffff88023e60d540 The intent behind this behavior was to return "pK-error" in cases where the %pK format specifier was used in interrupt context, because the CAP_SYSLOG check wouldn't be meaningful. Clearly this should only apply when kptr_restrict is actually enabled though. Reported-by:
