* kvm-arm64/mpam-ni: : Hiding FEAT_MPAM from KVM guests, courtesy of James Morse + Joey Gouly : : Fix a longstanding bug where FEAT_MPAM was accidentally exposed to KVM : guests + the EL2 trap configuration was not explicitly configured. As : part of this, bring in skeletal support for initialising the MPAM CPU : context so KVM can actually set traps for its guests. : : Be warned -- if this series leads to boot failures on your system, : you're running on turd firmware. : : As an added bonus (that builds upon the infrastructure added by the MPAM : series), allow userspace to configure CTR_EL0.L1Ip, courtesy of Shameer : Kolothum. KVM: arm64: Make L1Ip feature in CTR_EL0 writable from userspace KVM: arm64: selftests: Test ID_AA64PFR0.MPAM isn't completely ignored KVM: arm64: Disable MPAM visibility by default and ignore VMM writes KVM: arm64: Add a macro for creating filtered sys_reg_descs entries KVM: arm64: Fix missing traps of guest accesses to the MPAM registers arm64: cpufeature: discover CPU support for MPAM arm64: head.S: Initialise MPAM EL2 registers and disable traps arm64/sysreg: Convert existing MPAM sysregs and add the remaining entries Signed-off-by: Oliver Upton <oliver.upton@linux.dev> |

README
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.
