kernels exposed by the recent fixes to resource limits for 32-bit processes
on 64-bit kernels:
- Let ABIs expose their maximum stack size via a new pointer in sysentvec
and use that in preference to maxssiz during exec() rather than always
using maxssiz for all processses.
- Apply the ABI's limit fixup to the previous stack size when adjusting
RLIMIT_STACK to determine if the existing mapping for the stack needs to
be grown or shrunk (as well as how much it should be grown or shrunk).

to the FAT is possible.
Make the FAT block size less arbitrary before it is rounded up:
- for FAT12, default to 3*512 instead of to 3 sectors. The magic 3 is
the default number of 512-byte FAT sectors on a floppy drive. That
many sectors is too many if the sector size is larger.
- for !FAT12, default to PAGE_SIZE instead of to 4096. Remove
MSDOSFS_DFLTBSIZE since it only obfuscated this 4096.
For reading the BPB, use a block size of 8192 instead of 2048 so that
sector sizes up to 8192 can work. We should try several sizes, or just
try the maximum supported size (MAXBSIZE = 64K). I use 8192 because
that is enough for DVD-RW's (even 2048 is enough) and 8192 has been
tested a lot in use by ffs.
This completes fixing msdosfs for some large sector sizes (up to 8K
for read and 64K for write). Microsoft documents support for sector
sizes up to 4K in mdosfs. ffs is currently limited to 8K for both
read and write.

Rev 1.9 introduced another path where machclk_freq would be initialized
before the rest of setup was done (i.e. initializing the callout). Make
the one-time initialization a separate function and make init_machclk()
able to be called multiple times, any time. We depend on tsc_freq first
being updated from the highest priority eventhandler, thus we run last
and call init_machclk() to set machclk_freq. Also, don't initialize
static variables to 0.

part of fixing msdosfs for large sector sizes. One of the fixed bugs
was fatal for large sector sizes.
1. The fsinfo block has size 512, but it was misunderstood and declared
as having size 1024, with nothing in the second 512 bytes except a
signature at the end. The second 512 bytes actually normally (if
the file system was created by Windows) consist of a second boot
sector which is normally (in WinXP) empty except for a signature --
the normal layout is one boot sector, one fsinfo sector, another
boot sector, then these 3 sectors duplicated. However, other
layouts are valid. newfs_msdos produces a valid layout with one
boot sector, one fsinfo sector, then these 2 sectors duplicated.
The signature check for the extra part of the fsinfo was thus
normally checking the signature in either the second boot sector
or the first boot sector in the copy, and thus accidentally
succeeding. The extra signature check would just fail for weirder
layouts with 512-byte sectors, and for normal layouts with any other
sector size.
Remove the extra bytes and the extra signature check.
2. Old versions did i/o to the fsinfo block using size 1024, with the
second half only used for the extra signature check on read. This
was harmless for sector size 512, and worked accidentally for sector
size 1024. The i/o just failed for larger sector sizes.
The version being fixed did i/o to the fsinfo block using size
fsi_size(pmp) = (1024 << ((pmp)->pm_BlkPerSec >> 2)). This
expression makes no sense. It happens to work for sector small
sector sizes, but for sector size 32K it gives the preposterous
value of 64M and thus causes panics. A sector size of 32768 is
necessary for at least some DVD-RW's (where the minimum write size
is 32768 although the minimum read size is 2048).
Now that the size of the fsinfo block is 512, it always fits in
one sector so there is no need for a macro to express it. Just
use the sector size where the old code uses 1024.

ELF files. On ia64 the ELF header contains information about
characteristics of the machine code and ld(1) needs that to
determine whether input files are compatible for linking. To
this end non-ELF files are not supported by binutils on ia64.
However, the resulting ELF file seems to be correct despite the
warnings and the non-supportedness of non-ELF files and it
appears enough to unbreak the build of firmware(9) files on ia64
by simply supressing the warning.

vm_page_cowfault(). Initially, if vm_page_cowfault() sleeps, the given
page is wired, preventing it from being recycled. However, when
transmission of the page completes, the page is unwired and returned to
the page queues. At that point, the page is not in any special state
that prevents it from being recycled. Consequently, vm_page_cowfault()
should verify that the page is still held by the same vm object before
retrying the replacement of the page. Note: The containing object is,
however, safe from being recycled by virtue of having a non-zero
paging-in-progress count.
While I'm here, add some assertions and comments.
