Alan Cox a98a0090b2 arm64 pmap: Eliminate unnecessary TLB invalidations
Eliminate unnecessary TLB invalidations by pmap_kenter(),
pmap_qenter(), and pmap_mapbios() when the old page table entries
were invalid.

While I'm here, correct some nearby whitespace issues.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.
