PAGE_SIZE pages (4k). An average small program uses ~6 4k pages (24k),
while the same program only uses ~20 512 byte pages (10k), so it will be
a small memory usage improvement. The large improvement will be the upcoming
ability to share page table pages between processes for shared libraries.
Remaining: should be able to give back ptp pages to the system.

this is basically copy of what nfs_kq.c does - a thread periodically
polls server checking if any of the wateched files changed
eventually this should be changed to take advantage of SMB Directory

the beginning of the GOT, so we don't need an extra one here. Also, remove a
bogus comment -- we do in fact have to do fixups, because there are pointers in
ld.elf_so's data segment that need to be relocated.
not a flat text file (boo!). Use sed instead of perl, though. In-tree
tools are better.
Also, when inserted RCS tags into generated files, don't use a tag
that will get expanded in the Makefile; quote it such that it is
only expanded when the generated file is checked in.
(and associated targets for .dvi et al), as well as man pages from .pod,
using a prefix of `# '.
This prevents a variety of build issues caused by situations such as
cvs checkouts which result in the .texinfo file being slightly newer
than the .info file, and the build process trying to unnecessarily
regenerate them, which will fail in a variety of circumstances
(build tools not available, read-only source, etc ...)
Once a better solution is found, we can switch to it.
For now, this improves things greatly and should reduce a lot of
support requests that would undoubtably appear otherwise...
This improves performance a lot on slow machines behind a cable modem.
Protect it with PPPOE_SERVER as a reminder that this will have to be changed
if we add PPPoE server code in the kernel one day.
previous entry. (not if the current entry starts at the end of the new
space; that case doesn't take into account if the new space had a specified
alignment).
actually happens.
Add a new fcntl call that will write the minimum necessary to checkpoint
(i.e., for on-disk directory structure to be consistent, not including
updates to file data) so that the cleaner can clean segments more quickly
without sacrificing three-way commit for cleaning.
- Use _cpu_intr_suspend()/_cpu_intr_resume() in G2_LOCK/G2_UNLOCK macros
rather than _cpu_exception_suspend()/_cpu_exception_resume().
TLB miss exceptions could happen on accessing buffer, but it will never
block G2bus cycle anyway.
- Restore the previous SR.IMASK value in G2_UNLOCK().
- some misc cosmetics.
Should fix spontaneous reboots by "ping -s 8192 host" on the LAN Adapter.
