* kvm-arm64/sgi-injection: : vSGI injection improvements + fixes, courtesy Marc Zyngier : : Avoid linearly searching for vSGI targets using a compressed MPIDR to : index a cache. While at it, fix some egregious bugs in KVM's mishandling : of vcpuid (user-controlled value) and vcpu_idx. KVM: arm64: Clarify the ordering requirements for vcpu/RD creation KVM: arm64: vgic-v3: Optimize affinity-based SGI injection KVM: arm64: Fast-track kvm_mpidr_to_vcpu() when mpidr_data is available KVM: arm64: Build MPIDR to vcpu index cache at runtime KVM: arm64: Simplify kvm_vcpu_get_mpidr_aff() KVM: arm64: Use vcpu_idx for invalidation tracking KVM: arm64: vgic: Use vcpu_idx for the debug information KVM: arm64: vgic-v2: Use cpuid from userspace as vcpu_id KVM: arm64: vgic-v3: Refactor GICv3 SGI generation KVM: arm64: vgic-its: Treat the collection target address as a vcpu_id KVM: arm64: vgic: Make kvm_vgic_inject_irq() take a vcpu pointer Signed-off-by: Oliver Upton <oliver.upton@linux.dev>
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.
