Christoffer Dall 245715cbe8 KVM: arm/arm64: Fix lost IRQs from emulated physcial timer when blocked
When the VCPU is blocked (for example from WFI) we don't inject the
physical timer interrupt if it should fire while the CPU is blocked, but
instead we just wake up the VCPU and expect kvm_timer_vcpu_load to take
care of injecting the interrupt.

Unfortunately, kvm_timer_vcpu_load() doesn't actually do that, it only
has support to schedule a soft timer if the emulated phys timer is
expected to fire in the future.

Follow the same pattern as kvm_timer_update_state() and update the irq
state after potentially scheduling a soft timer.

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
