Linux kernel source tree
57e3869cfa
Refactor kvm_mips_host_tlb_inv() to also be able to invalidate any matching TLB entry in the kernel ASID rather than assuming only the TLB entries in the user ASID can change. Two new bool user/kernel arguments allow the caller to indicate whether the mapping should affect each of the ASIDs for guest user/kernel mode. - kvm_mips_invalidate_guest_tlb() (used by TLBWI/TLBWR emulation) can now invalidate any corresponding TLB entry in both the kernel ASID (guest kernel may have accessed any guest mapping), and the user ASID if the entry being replaced is in guest USeg (where guest user may also have accessed it). - The tlbmod fault handler (and the KSeg0 / TLB mapped / commpage fault handlers in later patches) can now invalidate the corresponding TLB entry in whichever ASID is currently active, since only a single page table will have been updated anyway.

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.
