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.

This variable was added in r82352 back in 2001, but even then it didn't
have any use. Because it's not marked static, the C compiler won't
complain about it.

Use the defined types instead of int when manipulating masks.
Supposedly, it could fix support for 32KB page size in the
machine-independend VM layer.
