There is no need to schedule and cancel a hrtimer when entering and exiting the guest, because we know when the physical timer is going to fire when the guest programs it, and we can simply program the hrtimer at that point. Now when the register modifications from the guest go through the kvm_arm_timer_set/get_reg functions, which always call kvm_timer_update_state(), we can simply consider the timer state in this function and schedule and cancel the timers as needed. This avoids looking at the physical timer emulation state when entering and exiting the VCPU, allowing for faster servicing of the VM when needed.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
