While trying to unify the pkey handling in show_smap() between x86 and powerpc we stumbled across various build failures due to the order of includes between the two arches. Part of the problem is that linux/pkeys.h includes asm/mmu_context.h, and the relationship between asm/mmu_context.h and asm/pkeys.h is not consistent between the two arches. It would be cleaner if linux/pkeys.h only included asm/pkeys.h, creating a single integration point for the arch pkey definitions. So this patch removes the include of asm/mmu_context.h from linux/pkeys.h. We can't prove that this is safe in the general case, but it passes all the build tests I've thrown at it. Also asm/mmu_context.h is included widely while linux/pkeys.h is not, so most likely any code that is including linux/pkeys.h is already getting asm/mmu_context.h from elsewhere.

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.
