allocate the requested page because too few pages are cached or free.
Document the VM_ALLOC_COUNT() option to vm_page_alloc() and
vm_page_alloc_freelist().
Make style changes to vm_page_alloc() and vm_page_alloc_freelist(),
such as using a variable name that more closely corresponds to the
comments.
Because SEEK_SET is 0, this seems to have no effect on the generated code.

make.conf(5), while allowing the build32 stage on 64-bit architectures
to still override them, so that stage can successfully build 32-bit
compatibility libraries.
Explanation:
1) The build32 stage sets environment variables CC, CXX, AS and LD for
its sub-make, to add 32-bit specific flags (-m32 and such).
2) The sub-make reads sys.mk, encounters CC?= and CXX?= assignments, so
does not alter them.
3) After some other stuff, sys.mk reads /etc/make.conf. When you have
"CC=xxx" and "CXX=yyy" statements in there, they will *override* the
build32-supplied CC/CXX values, nullifying the 32-bit specific flags.
4) Thus all objects get built as 64-bit anyway, and since LD is usually
not set in make.conf, it still has the 32-bit flags!
5) Now, whenever something is linked, you will get a "ld: Relocatable
linking with relocations from format elf64-x86-64-freebsd (foo.o) to
format elf32-i386-freebsd (bar.o) is not supported" error.
Fix this by adding "-ECC -ECXX -EAS -ELD" to the build32 sub-make
invocation, which forces those environment variables to always override
any assignment in makefiles. Thus making it possible to simply set:
CC=my-cc
CXX=my-c++
in your make.conf, or specify a path, even:
CC=/usr/local/bin/other-cc
CXX=/usr/local/bin/other-c++
Note this was never a problem on i386, since it has no build32 stage.

document knlist_delete, and better document what knlist_clear does... Note
that both of these functions may sleep, and also unlock/relock the list
lock...
document knlist_init_mtx (forgotten by kib)...

the /etc/rc.d/nfsd script sets vfs.nfsd.server_max_nfsvers to 3.
Then, when you set nfsv4_server_enable=YES in rc.conf, and restart nfsd
via the rc.d script, without rebooting, the sysctl does *not* get reset
to max version 4, so NFSv4 still doesn't work.
Fix this by explicitly setting vfs.nfsd.server_max_nfsvers to 4 when
NFSv4 is requested.
I also added resetting of the nfs_privport sysctls, since this has the
same issue: nfs_reserved_port_only=YES in rc.conf sets the nfs_privport
sysctl to 1, but in the other case, the sysctl doesn't get reset to 0.
