int Version_* is only used with ksymoops, which is only needed (according
to README and Documentation/Changes) if CONFIG_KALLSYMS is NOT defined.
Therefore this patch defines version_string only if CONFIG_KALLSYMS is not

Inflate requires some dynamic memory allocation very early in the boot
process and this is provided with a set of four functions:
malloc/free/gzip_mark/gzip_release.The old inflate code used a mark/release strategy rather than implement
free. This new version instead keeps a count on the number of outstanding
allocations and when it hits zero, it resets the malloc arena.This allows removing all the mark and release implementations and unifying
all the malloc/free implementations.The architecture-dependent code must define two addresses:
- free_mem_ptr, the address of the beginning of the area in which
allocations should be made
- free_mem_end_ptr, the address of the end of the area in which
allocations should be made. If set to 0, then no check is made on
the number of allocations, it just grows as much as neededThe architecture-dependent code can also provide an arch_decomp_wdog()
function call. This function will be called several times during the
decompression process, and allow to notify the watchdog that the system is
still running. If an architecture provides such a call, then it must
define ARCH_HAS_DECOMP_WDOG so that the generic inflate code calls
arch_decomp_wdog().Work initially done by Matt Mackall, updated to a recent version of the
kernel and improved by me.[akpm@linux-foundation.org: coding-style fixes]

This driver adds support for reading and configuring certain information
on modern HP laptops with WMI BIOS interfaces. It supports enabling and
disabling the ambient light sensor, querying attached displays and hard
drive temperature, sending events on docking and querying the state of the
dock and toggling the state of the wifi, bluetooth and wwan hardware via
rfkill. It also makes the little "(i)" button work on machines that send
that via WMI rather than via the keyboard controller.Signed-off-by: Matthew Garrett

Presently call_usermodehelper_setup() uses GFP_ATOMIC. but it can return
NULL _very_ easily.GFP_ATOMIC is needed only when we can't sleep. and, GFP_KERNEL is robust
and better.thus, I add gfp_mask argument to call_usermodehelper_setup().
So, its callers pass the gfp_t as below:
call_usermodehelper() and call_usermodehelper_keys():
depend on 'wait' argument.
call_usermodehelper_pipe():
always GFP_KERNEL because always run under process context.
orderly_poweroff():
pass to GFP_ATOMIC because may run under interrupt context.Signed-off-by: KOSAKI Motohiro

Several compilers offer "long long" without claiming to support C99.
Considering how frequent __s64/__u64 are used our userspace headers are
anyway unusable without __s64/__u64 available.Always offer __s64/__u64 to non-gcc non-C99 compilers - if they provide
"long long" that makes the headers compiling and if they don't they are
anyway screwed.Signed-off-by: Adrian Bunk

Build kernel/profile.o only if CONFIG_PROFILING is enabled.
This makes CONFIG_PROFILING=n kernels smaller.
As a bonus, some profile_tick() calls and one branch from schedule() are
now eliminated with CONFIG_PROFILING=n (but I doubt these are
measurable effects).This patch changes the effects of CONFIG_PROFILING=n, but I don't think
having more than two choices would be the better choice.This patch also adds the name of the first parameter to the prototypes
of profile_{hits,tick}() since I anyway had to add them for the dummy
functions.Signed-off-by: Adrian Bunk

In many cases, especially in networking, it can be beneficial to know at
compile time whether the architecture can do unaligned accesses efficiently.
This patch introduces a new Kconfig symbolHAVE_EFFICIENT_UNALIGNED_ACCESS
for that purpose and adds it to the powerpc and x86 architectures. Also add
some documentation about alignment and networking, and especially one intended
use of this symbol.Signed-off-by: Johannes Berg

Remove the conditional surrounding the definition of list_add() from list.h
since, if you define CONFIG_DEBUG_LIST, the definition you will subsequently
pick up from lib/list_debug.c will be absolutely identical, at which point you
can remove that redundant definition from list_debug.c as well.Signed-off-by: Robert P. J. Day

Extend memparse() to allow the caller to use a NULL second parameter, which
would represent no interest in returning the address of the end of the parsed
string.In numerous cases, callers invoke memparse() to parse a possibly-suffixed
string (such as "64K" or "2G" or whatever) and define a character pointer to
accept the end pointer being returned by memparse() even though they have no
interest in it and promptly throw it away.This (backward-compatible) enhancement allows callers to use NULL in the cases
where they just don't care about getting back that end pointer.[akpm@linux-foundation.org: coding-style fixes]

Currently, checkstack.pl only looks for fixed subtractions from the stack
pointer. However, things like this:void function(int size)
{
char stackbuster[size << 2];
...are certainly worth pointing out, I think.
This could perhaps be done more cleanly, and the following patch only
adds "dynamic" REs for x86 and x86_64, but it works:0x00b0 crypto_cbc_decrypt_inplace [cbc]: Dynamic (%rax)
0x00ad crypto_pcbc_decrypt_inplace [pcbc]: Dynamic (%rax)
0x02f6 crypto_pcbc_encrypt_inplace [pcbc]: Dynamic (%rax)
0x036c _crypto_xcbc_digest_setkey [xcbc]: Dynamic (%rax)

Changeset 7fa897b91a3ea0f16c2873b869d7a0eef05acff4 ("ide: trivial sparse
annotations") created an IDE bootup regression on big-endian systems.In drivers/ide/ide-iops.c, function ide_fixstring() we now have the
loop:for (p = end ; p != s;)
be16_to_cpus((u16 *)(p -= 2));which will never terminate on big-endian because in such
a configuration be16_to_cpus() evaluates to "do { } while (0)"Therefore, always evaluate the arguments to nop endian transformation
