Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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:
"Nine small fixes.
The resume fix is a cosmetic removal of a warning with an incorrect
condition causing it to alarm people wrongly.
The other eight patches correct a thinko in Christoph Hellwig's DMA
conversion series. Without it all these drivers end up with 32 bit DMA
masks meaning they bounce any page over 4GB before sending it to the
controller.
Nowadays, even laptops mostly have memory above 4GB, so this can lead
to significant performance degradation with all the bouncing"

The max flush rep count of HvFlushGuestPhysicalAddressList hypercall is
equal with how many entries of union hv_gpa_page_range can be populated
into the input parameter page.
The code lacks parenthesis around PAGE_SIZE - 2 * sizeof(u64) which results
in bogus computations. Add them.

scsi_device_quiesce() and scsi_device_resume() are called during
system-wide suspend and resume. scsi_device_quiesce() only succeeds for
SCSI devices that are in one of the RUNNING, OFFLINE or TRANSPORT_OFFLINE
states (see also scsi_set_device_state()). This patch avoids that the
following warning is triggered when resuming a system for which quiescing a
SCSI device failed:

When calling __put_user(foo(), ptr), the __put_user() macro would call
foo() in between __uaccess_begin() and __uaccess_end(). If that code
were buggy, then those bugs would be run without SMAP protection.
Fortunately, there seem to be few instances of the problem in the
kernel. Nevertheless, __put_user() should be fixed to avoid doing this.
Therefore, evaluate __put_user()'s argument before setting AC.
This issue was noticed when an objtool hack by Peter Zijlstra complained
about genregs_get() and I compared the assembly output to the C source.

commit 137cd7100ec6fa36d610e106df00acb4d8af99df
"ARM: dts: Enable Gemini flash access" contained a bug
by disabling the display controller, while the whole
idea with the patch was to enable flash access AND
the display controller, simultaneously. Fix it up.
