This tag contains the following changes for kernel 5.7:
- MMU code improvements that includes:
- Flush MMU TLB cache only once, at the end of mapping/unmapping
function, instead of flushing after mapping of every page.
- Add future ASIC support by splitting properties of ASIC capabilities
regarding mapping of host memory to regular and huge pages.
- Add debugfs interface to write and read 64-bit values from the device's
memory/registers. Previously the driver provided interface for 32-bit
values and this will allow the user to debug much more quickly. We saw it
gives a boost of around 1.5 - 1.7 when reading internal memories.
- Support temperature offset via sysfs as defined in
https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface
- Display historical maximum of various sensors.
- Print to kernel log when clock throttling occurs to due breach of power
or thermal envelope. Also prints when clock throttling is finished
(clock is back to optimal).
- Fix bug when moving from manual to auto power-management mode.
- Print a message ("unsupported device") to kernel log in case a GAUDI device
is recognized.
- Small bug fixes and minor improvements to code.

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.
