* kvm-arm64/nv-pmu:
: Support for vEL2 PMU controls
:
: Align the vEL2 PMU support with the current state of non-nested KVM,
: including:
:
: - Trap routing, with the annoying complication of EL2 traps that apply
: in Host EL0
:
: - PMU emulation, using the correct configuration bits depending on
: whether a counter falls in the hypervisor or guest range of PMCs
:
: - Perf event swizzling across nested boundaries, as the event filtering
: needs to be remapped to cope with vEL2
KVM: arm64: nv: Reprogram PMU events affected by nested transition
KVM: arm64: nv: Apply EL2 event filtering when in hyp context
KVM: arm64: nv: Honor MDCR_EL2.HLP
KVM: arm64: nv: Honor MDCR_EL2.HPME
KVM: arm64: Add helpers to determine if PMC counts at a given EL
KVM: arm64: nv: Adjust range of accessible PMCs according to HPMN
KVM: arm64: Rename kvm_pmu_valid_counter_mask()
KVM: arm64: nv: Advertise support for FEAT_HPMN0
KVM: arm64: nv: Describe trap behaviour of MDCR_EL2.HPMN
KVM: arm64: nv: Honor MDCR_EL2.{TPM, TPMCR} in Host EL0
KVM: arm64: nv: Reinject traps that take effect in Host EL0
KVM: arm64: nv: Rename BEHAVE_FORWARD_ANY
KVM: arm64: nv: Allow coarse-grained trap combos to use complex traps
KVM: arm64: Describe RES0/RES1 bits of MDCR_EL2
arm64: sysreg: Add new definitions for ID_AA64DFR0_EL1
arm64: sysreg: Migrate MDCR_EL2 definition to table
arm64: sysreg: Describe ID_AA64DFR2_EL1 fields

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.
