Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.

Pull SCSI fixes from James Bottomley:
- a couple of serious fixes: use after free and blacklist for WRITE
SAME
- one error leg fix: write_pending failure
- one user experience problem: do not override max_sectors_kb
- one minor unused function removal
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: ibmvscsis: Fix write_pending failure path
scsi: libiscsi: Remove iscsi_destroy_session

Pull i2c fixes from Wolfram Sang:
"I2C has three driver fixes for the newly introduced drivers and one ID
addition for the i801 driver"
* 'i2c/for-current-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
i2c: i2c-stm32f7: make structure stm32f7_setup static const
i2c: ensure termination of *_device_id tables
i2c: i801: Add support for Intel Cedar Fork
i2c: stm32f7: fix setup structure
For write_pending if the queue is down or client failed then return -EIO
so that LIO can properly process the completed command. Prior we
returned 0 since LIO could not handle it properly. Now with commit
fa7e25cf13a6 ("target: Fix unknown fabric callback queue-full errors")
that patch addresses LIO's ability to handle things right.

Pull MMC fixes from Ulf Hansson:
"MMC core:
- Fix driver strength selection when selecting hs400es
- Delete bounce buffer handling:
This change fixes a problem related to how bounce buffers are being
allocated. However, instead of trying to fix that, let's just
remove the mmc bounce buffer code altogether, as it has practically
no use.

- meson-gx: A couple of fixes related to clock/phase/tuning
- sdhci-xenon: Fix clock resource by adding an optional bus clock"

The structure stm32f7_setup is local to the source and does not need
to be in global scope, make it static const.
Cleans up sparse warning:
symbol 'stm32f7_setup' was not declared. Should it be static?

On Armada 7K/8K we need to explicitly enable the bus clock. The bus clock
is optional because not all the SoCs need them but at least for Armada
7K/8K it is actually mandatory.
The binding documentation is updating accordingly.
Without this patch the kernel hand during boot if the mvpp2.2 network
driver was not present in the kernel. Indeed the clock needed by the
xenon controller was set by the network driver.

Session attributes exposed through sysfs were freed before the device
was destroyed, resulting in a potential use-after-free. Free these
attributes after removing the device.

Pull clk fixes from Stephen Boyd:

across suspend

Rockchip SoCs
- a fix for a copy-paste mistake on Rockchip rk3128 causing some clks
to touch the same bit and trample over one another

Commit 2ca492e22cb7 has moved the call to 'kfifo_alloc()' from after the
main 'if' statement to before it.
But it has not updated the error handling paths accordingly.
Fix all that:
- if 'kfifo_alloc()' fails we can return directly
- direct returns after 'kfifo_alloc()' must now go to 'out_mbox_free'
- 'goto out_mbox_free' must be replaced by 'goto out', otherwise the
'[pcc_]mbox_free_channel()' call will be missed.

It has been reported that some platforms (odroid-c2) may require
a different tx phase setting to operate at high speed (hs200 and hs400)
To improve the situation, this patch includes tx phase in the tuning
process.
