longs larger than 32 bits or strict alignment requirements. pm_fatmask had type u_long, but it must have a type that has precisely 32 bits and this type must be no smaller than int, so that ~pmp->pm_fatmask has no bits above the 31st set. Otherwise, comparisons between (cn | ~pmp->pm_fatmask) and magic 32-bit "cluster" numbers always fail. The correct fix is to use the C99 type uint_least32_t and mask with 0xffffffff. The quick fix is to use u_int32_t and assume that ints have msdosfs metadata is riddled with unaligned fields, and on alphas, unaligned_fixup() apparently has problems fixing up the unaligned accesses caused by this. The quick fix is to not comment out the NetBSD code that sort of handles this, and define UNALIGNED_ACCESS on i386's so that the code doesn't change on i386's. The correct fix would define UNALIGNED_ACCESS in a central machine-dependent header and maybe add some extra cases to unaligned_fixup(). UNALIGNED_ACCESS is also tested in isofs.

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 ``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/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 have to build world before. More information is available in the handbook. 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 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.
