the 32 and 64 files define MACHINE_ARCH, CC, LD and AS appropriately to build
a 32 or 64 bit kernel, respectively. this allows either to be built on a
system that can generate 32 or 64 bit code.
cylinder groups to work correctly, with minor modifications by me to work
with our FFS_EI code. From the FreeBSD commit message:
The ffs superblock includes a 128-byte region for use by temporary
in-core pointers to summary information. An array in this region
(fs_csp) could overflow on filesystems with a very large number of
cylinder groups (~16000 on i386 with 8k blocks). When this happens,
other fields in the superblock get corrupted, and fsck refuses to
check the filesystem.
Solve this problem by replacing the fs_csp array in 'struct fs'
with a single pointer, and add padding to keep the length of the
128-byte region fixed. Update the kernel and userland utilities
to use just this single pointer.
With this change, the kernel no longer makes use of the superblock
fields 'fs_csshift' and 'fs_csmask'. Add a comment to newfs/mkfs.c
to indicate that these fields must be calculated for compatibility
with older kernels.

code considerably and was mainly providing SGI specific logging facilities
and some hacks to improve the relyablility on SGI systems by increasing
priorities etc...
in how interrupts are down- the 23XX has not only a different place to check
for an interrupt, but unlike all other QLogic cards, you have to read the
status as a 32 bit word- not 16 bit words. Rather than have device specific
functions as called from the core module (in isp_intr), it makes more sense
to have the platform/bus modules do the gruntwork of splitting out the
isr, semaphore register and the first outgoing mailbox register (if needed)
*prior* to calling isp_intr (if calling isp_intr is necessary at all).
- Don't need to include <sys/time.h>, <sys/resource.h> does.
- Include <limits.h> for LONG_MIN/LONG_MAX.
- Be consistant with usage of (void) in front of printf()/fprintf().
- Sort include files.
- ANSIfy.
you've got to pad the text just like with 4.3BSD binaries.
fix it.
i have now successfully tested compat-vax1k with real
o/m/z magic binaries from both 4.3BSD and netbsd 1.3.
NetBSD's default security policy in this area: if you are not on
a secure terminal, you must be able to authenticate as a user in
the "wheel" group before you may attempt to authenticate as root
using the root password.
- Cast blk argument to lblktosize() to (off_t), to prevent 32 bit overflow.
whilst almost every use in ffs used this for small blknos, there are
potential issues, and it's safer this way. (as discussed with chuq)
- Use 64bit (off_t) math to calculate if we have hit our freespace() limit.
Necessary for coherent results on filesystems bigger than 0.5Tb.
- Use lblktosize() in blksize() and dblksize(), to make it obvious what's
happening
- Remove sblksize() - nothing uses it
- if _fs_fstab.fs_type is NULL, the line is incorrect, so warn about it
rather than trying to deference a NULL pointer.
fixes [bin/13787] by Dave Burgess.
- clear _fs_fstab before each use (just to be sure)
