The mmu context on the 40x, 44x does not define pte_frag entry. This
causes gcc abort the compilation due to:
setup-common.c: In function ‘setup_arch’:
setup-common.c:908: error: ‘mm_context_t’ has no ‘pte_frag’
This patch fixes the issue by removing the pte_frag initialization in
setup-common.c.
This is possible, because the compiler will do the initialization,
since the mm_context is a sub struct of init_mm. init_mm is declared
in mm_types.h as external linkage.
According to C99 6.2.4.3:
An object whose identifier is declared with external linkage
[...] has static storage duration.
C99 defines in 6.7.8.10 that:
If an object that has static storage duration is not
initialized explicitly, then:
- if it has pointer type, it is initialized to a null pointer

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.
