Use pmap_find_pv if needed instead of multiplying its code throughout pmap-v6. Avoid possible NULL pointer dereference in pmap_enter_locked() When trying to get m->md.pv_memattr, make sure that m != NULL, in particular that vector_page is set to be NULL. Do not set PGA_REFERENCED flag in pmap_enter_pv(). On ARM any new page reference will result in either entering the new mapping by calling pmap_enter, etc. or fixing-up the existing mapping in pmap_fault_fixup(). Therefore we set PGA_REFERENCED flag in the earlier mentioned cases and setting it later in pmap_enter_pv() is just waste of cycles. Delete unused pm_pdir pointer from the pmap structure. Rearrange brackets in the fault cause detection in trap.c Place the brackets correctly in order to see course of the conditions instantaneously. Unify naming in pmap-v6.c and improve style Use naming common for whole pmap and compatible with other pmaps, improve style where possible: pm -> pmap pg -> m opg -> om *pt -> *ptep *pte -> *ptep *pde -> *pdep Submitted by: Zbigniew Bodek <zbb@semihalf.com> Sponsored by: The FreeBSD Foundation, Semihalf |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
