e0e2fa4b51 headers_install.pl: convert to headers_install.sh
Remove perl from make headers_install by replacing a perl script (doing a
simple regex search and replace) with a smaller, faster, simpler,
POSIX-2008 shell script implementation.  The new shell script is a single
for loop calling sed and piping its output through unifdef to produce the
target file.

Same as last time except for minor tweak to deal with code review from
here: http://lkml.indiana.edu/hypermail/linux/kernel/1302.3/00078.html

(Note that this drops the "arch" argument, which isn't used. Kbuild
already points to the right input files on the command line.)

a6e4d5a03e x86, efivars: firmware bug workarounds should be in platform code
Let's not burden ia64 with checks in the common efivars code that we're not
writing too much data to the variable store. That kind of thing is an x86
firmware bug, plain and simple.

efi_query_variable_store() provides platforms with a wrapper in which they can
perform checks and workarounds for EFI variable storage bugs.

Currently we check to see if we obtained the Tightly Coupled Program

85747311ec i2c: s3c2410: Add SMBus emulation for block read
SMBus read and write are supported by the emulation layer of i2c
framework if the controller doesn't have SMBus features.

I2C_M_RECV_LEN flag is used to let i2c drivers know rx length is not
yet determined but will be read to the first byte in rx buffer.

s3c2410 doesn't handle this flag. So only one byte is read from slave.
There fore following two features are added to the driver code.

1. skip rx length check if I2C_M_RECV_LEN is set and the length is 1.
2. add actual bytes to the rx length after reading first bytes if
   I2C_M_RECV_LEN.

I2C_M_RECV_LEN is only set for SMBus command. So this code does not
affect legacy codes which only use i2c command for s3c2410.

399368372e f2fs: introduce a new global lock scheme
In the previous version, f2fs uses global locks according to the usage types,
such as directory operations, block allocation, block write, and so on.

Reference the following lock types in f2fs.h.
enum lock_type {
	RENAME,		/* for renaming operations */
	DENTRY_OPS,	/* for directory operations */
	DATA_WRITE,	/* for data write */
	DATA_NEW,	/* for data allocation */
	DATA_TRUNC,	/* for data truncate */
	NODE_NEW,	/* for node allocation */
	NODE_TRUNC,	/* for node truncate */
	NODE_WRITE,	/* for node write */
	NR_LOCK_TYPE,
};

In that case, we lose the performance under the multi-threading environment,
since every types of operations must be conducted one at a time.

In order to address the problem, let's share the locks globally with a mutex
array regardless of any types.
So, let users grab a mutex and perform their jobs in parallel as much as
possbile.

For this, I propose a new global lock scheme as follows.

0. Data structure
 - f2fs_sb_info -> mutex_lock[NR_GLOBAL_LOCKS]
 - f2fs_sb_info -> node_write

1. mutex_lock_op(sbi)
 - try to get an avaiable lock from the array.
 - returns the index of the gottern lock variable.

2. mutex_unlock_op(sbi, index of the lock)
 - unlock the given index of the lock.

3. mutex_lock_all(sbi)
 - grab all the locks in the array before the checkpoint.

4. mutex_unlock_all(sbi)
 - release all the locks in the array after checkpoint.

5. block_operations()
 - call mutex_lock_all()
 - sync_dirty_dir_inodes()
 - grab node_write
 - sync_node_pages()

Note that,
 the pairs of mutex_lock_op()/mutex_unlock_op() and
 mutex_lock_all()/mutex_unlock_all() should be used together.

This extra I/O memory range is needed when using the PFC

however to use a separate GPIO driver in the long run
and when that happens this extra I/O memory range can

1127a3d448 f2fs: move f2fs_balance_fs from truncate to punch_hole
Move the f2fs_balance_fs out of the truncate_hole function and only
perform that in punch_hole use case.  The commit:

  ed60b1644e7f7e5dd67d21caf7e4425dff05dad0

intended to do this but moved it into truncate_hole to cover more
cases.  However, a deadlock scenario is possible when deleting an inode
entry under specific conditions:

 f2fs_delete_entry()
     mutex_lock_op(sbi, DENTRY_OPS);
     truncate_hole()
         f2fs_balance_fs()
             mutex_lock(&sbi->gc_mutex);
             f2fs_gc()
                 write_checkpoint()
                     block_operations()
                         mutex_lock_op(sbi, DENTRY_OPS);

Lets move it into the punch_hole case to cover the original intent of
avoiding it during fallocate's expand_inode_data case.

6394678e6e mfd: wm8994: Don't use system PM operations
For realistic systems the power management is controlled entirely via
runtime PM - if the device is not runtime suspended then the suspend
will abort without doing anything as functionality such as accessory
detection or audio bypass will require the device to be enabled while
if the device is runtime suspended it is already in the lowest power
state. This means that system suspend is redundant and can be removed
which avoids issues with attempting to double disable the regulators.

3cec5f4e75 mfd: da9055: Change irq state to default
This patch changes the irq state from high to the now default low.
Because the default PMIC irq state of DA9055 got changed from high to low.
This change should not affect any of the existing users since all of them
use active low state.

This patch has been tested on smdkv6410.

We also move channel clock management from runtime PM handlers into

This patch replaces statically hardcoded register offsets of Exynos SoCs

Thanks to this change, support for SoCs with other set and order of
registers can be added (e.g. S3C24xx and S3C64xx).

499147c9db pinctrl: samsung: Split pin bank description into two structures
This patch splits pin bank description into two structures, one
describing bank type (currently only bitfield widths), which can be
shared across multiple banks and second containing bank-specific
parameters including a pointer to a bank type struct.

It is a prerequisite for further patch removing the statically hardcoded
register offsets, making it impossible to support SoCs with different
set and order of pin control registers.

Certain pin control registers can be accessed from different contexts,
i.e. pinctrl, gpio and irq functions. This makes the locking provided by
pin control core insufficient.

This patch adds necessary locking using a per bank spinlock as it was
done in the old Samsung GPIO driver.

104058ede7 ARC: [build] Allow uncompressed uImage
The existing uImage target always generates gzip compressed image which
drags bootup for some very slow FPGA customer boards.

So introduce seperate make targets:uImage.{bin,gz} with uncompressed
being default. Also tie gz generation to CONFIG_KERNEL_GZIP, which a
platform can select in it's Kconfig if it wishes gz to be default.
