KVM/arm64 updates for 6.12
* New features:
- Add a Stage-2 page table dumper, reusing the main ptdump
infrastructure, and allowing easier debugging of the our
page-table infrastructure
- Add FP8 support to the KVM/arm64 floating point handling.
- Add NV support for the AT family of instructions, which mostly
results in adding a page table walker that deals with most of the
complexity of the architecture.
* Improvements, fixes and cleanups:
- Add selftest checks for a bunch of timer emulation corner cases
- Fix the multiple of cases where KVM/arm64 doesn't correctly handle
the guest trying to use a GICv3 that isn't advertised
- Remove REG_HIDDEN_USER from the sysreg infrastructure, making
things little more simple
- Prevent MTE tags being restored by userspace if we are actively
logging writes, as that's a recipe for disaster
- Correct the refcount on a page that is not considered for MTE tag
copying (such as a device)
- Relax the synchronisation when walking a page table to split block
mappings, moving it at the end the walk, as there is no need to
perform it on every store.
- Fix boundary check when transfering memory using FFA
- Fix pKVM TLB invalidation, only affecting currently out of tree
code but worth addressing for peace of mind
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 reStructuredText 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.
