ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

4152886f7a For the on-the-wire protocol, u_long -> u_int32_t; long -> int32_t;
int -> int32_t; u_short -> u_int16_t.  Also, use mode_t instead of u_short
for storing modes (mode_t is a u_int16_t).

c03d64df19 NetBSD has a comment that Solaris 2.5 doesn't do verifiers correctly,
we have weakened this test already for Digital Unix, so it may be enough
for Solaris.  It needs to be checked again.

e8cf20c8db NFS Jumbo commit part 1. Cosmetic and structural changes only. The aim
of this part of commits is to minimize unnecessary differences between
the other NFS's of similar origin.  Yes, there are gratuitous changes here
that the style folks won't like, but it makes the catch-up less difficult.

7c1c33a7dd When using NFSv3, use the remote server's idea of the maximum file size
rather than assuming 2^64.  It may not like files that big. :-)
On the nfs server, calculate and report the max file size as the point
that the block numbers in the cache would turn negative.
(ie: 1099511627775 bytes (1TB)).

One of the things I'm worried about however, is that directory offsets
are really cookies on a NFSv3 server and can be rather large, especially
when/if the server generates the opaque directory cookies by using a local
filesystem offset in what comes out as the upper 32 bits of the 64 bit
cookie.  (a server is free to do this, it could save byte swapping
depending on the native 64 bit byte order)

0d7d0fcf29 Convert a couple of large allocations to use zones rather than malloc
for better packing.  This means that we can choose better values for the
various hash entries without having to try and get it all to fit within
an artificial power of two limit for malloc's sake.

4204769d9e Only ignore "owner" permissions selectively rather than always. In some
cases we ignore it (eg: read/write) to maintain chmod-after-open semantics
but in other cases we do care, eg: creating files, access() etc.  Never
ignore errors from VOP_ACCESS() on immutable files.

This apparently comes from BSDI (from Keith Bostic) via NetBSD.

fe6c0d4599 Allow control of the attribute cache timeouts at mount time.
We had run out of bits in the nfs mount flags, I have moved the internal
state flags into a seperate variable.  These are no longer visible via
statfs(), but I don't know of anything that looks at them.

7be2d30077 In the words of the submitter:
---------
Make callers of namei() responsible for releasing references or locks
instead of having the underlying filesystems do it.  This eliminates
redundancy in all terminal filesystems and makes it possible for stacked
transport layers such as umapfs or nullfs to operate correctly.

Quality testing was done with testvn, and lat_fs from the lmbench suite.

Some NFS client testing courtesy of Patrik Kudo.

vop_mknod and vop_symlink still release the returned vpp.  vop_rename
still releases 4 vnode arguments before it returns.  These remaining cases
will be corrected in the next set of patches.

227ee8a188 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

Change profiling in ncr.c to use ticks instead of time.  Resolution is
the same.

Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

bc3de552ad Moved declaration of `union nethostadr' outside of the KERNEL section,
to give pollution compatible with <nfs/nqfs.h>.  At least mount_nfs.c
previously had to #define KERNEL before including <nfs/nfs.h> to get
this pollution, but this gave other pollution.

Moved comment about NFSINT_SIGMASK to immediately before the code that
it applies to.

eaf13dd73a Change the busy page mgmt, so that when pages are freed, they
MUST be PG_BUSY.  It is bogus to free a page that isn't busy,
because it is in a state of being "unavailable" when being
freed.  The additional advantage is that the page_remove code
has a better cross-check that the page should be busy and
unavailable for other use.  There were some minor problems
with the collapse code, and this plugs those subtile "holes."

Also, the vfs_bio code wasn't checking correctly for PG_BUSY
pages.  I am going to develop a more consistant scheme for
grabbing pages, busy or otherwise.  For now, we are stuck
with the current morass.

2be70f79f6 Lots of improvements, including restructring the caching and management
of vnodes and objects.  There are some metadata performance improvements
that come along with this.  There are also a few prototypes added when
the need is noticed.  Changes include:

1) Cleaning up vref, vget.
2) Removal of the object cache.
3) Nuke vnode_pager_uncache and friends, because they aren't needed anymore.
4) Correct some missing LK_RETRY's in vn_lock.
5) Correct the page range in the code for msync.

Be gentle, and please give me feedback asap.

638493a3c4 Don't call malloc(..., M_WAITOK) at splnet(). Doing so is often
a mistake (since softnet interrupts may occur if malloc() waits),
and doing it harmlessly but unnecessarily here interfered with

cb226aaa62 Move the "retval" (3rd) parameter from all syscall functions and put
it in struct proc instead.

This fixes a boatload of compiler warning, and removes a lot of cruft
from the sources.

I have not removed the /*ARGSUSED*/, they will require some looking at.

libkvm, ps and other userland struct proc frobbing programs will need
recompiled.

99448ed11d Change the M_NAMEI allocations to use the zone allocator. This change
plus the previous changes to use the zone allocator decrease the useage
of malloc by half.  The Zone allocator will be upgradeable to be able
to use per CPU-pools, and has more intelligent usage of SPLs.  Additionally,
it has reasonable stats gathering capabilities, while making most calls
inline.
