Instead of hard-checking for certain vendor codes, follow the pattern of
other AMBA (PrimeCell) drivers and use variables in the vendor data.
Get rid of the locally cached vendor and hardware revision since we
already have the nice vendor data variable in the state.Signed-off-by: Linus Walleij

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 + sizeThe patch unifies them to "start + size". Even if applying the patch,
/sys/firmware/memmap/X/end file content does not change.[akpm@linux-foundation.org: clarify comments]

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: Stephen Boyd

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: Akinobu Mita

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']

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

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: Stevie Trujillo
