* kvm-arm64/nv-resx-fixes-6.14: : . : Fixes for NV sysreg accessors. From the cover letter: : : "Joey recently reported that some rather basic tests were failing on : NV, and managed to track it down to critical register fields (such as : HCR_EL2.E2H) not having their expect value. : : Further investigation has outlined a couple of critical issues: : : - Evaluating HCR_EL2.E2H must always be done with a sanitising : accessor, no ifs, no buts. Given that KVM assumes a fixed value for : this bit, we cannot leave it to the guest to mess with. : : - Resetting the sysreg file must result in the RESx bits taking : effect. Otherwise, we may end-up making the wrong decision (see : above), and we definitely expose invalid values to the guest. Note : that because we compute the RESx masks very late in the VM setup, we : need to apply these masks at that particular point as well. : [...]" : . KVM: arm64: nv: Apply RESx settings to sysreg reset values KVM: arm64: nv: Always evaluate HCR_EL2 using sanitising accessors Signed-off-by: Marc Zyngier <maz@kernel.org> # Conflicts: # arch/arm64/kvm/nested.c
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.
