commit fe2b73dba4 upstream.
The code in decode_config4() of arch/mips/kernel/cpu-probe.c
asid_mask = MIPS_ENTRYHI_ASID;
if (config4 & MIPS_CONF4_AE)
asid_mask |= MIPS_ENTRYHI_ASIDX;
set_cpu_asid_mask(c, asid_mask);
set asid_mask to cpuinfo->asid_mask.
So in order to support variable ASID_MASK, KVM_ENTRYHI_ASID should also
be changed to cpu_asid_mask(&boot_cpu_data).

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.
