for syscalls, so one frame was lost in backtraces from syscalls. This is handled better in the kernel by using a different mcount entry point for profiling before the frame pointer is set up. Expand RCSID(). Use .p2align instead of the ambiguous .align. Added idempotency ifdef. Removed unused macros ALTENTRY(), ALTASENTRY(), ASENTRY(), _MID_ENTRY. Cleaned up formatting.

This is the top level of the FreeBSD source directory. This file was last revised on: $Id$ 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. Please see the top of the Makefile for more information on the standard build targets and compile-time flags. Building a kernel with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/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 LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
