I recommend port masters of other archs to consider doing the same.

reserve some more space for the BSS section than the binary says. This
trick was used to leave room after the kernel's image to copy the symbol
table following the format required by ksyms_init. (It was also used to
workaround a bug in the physical address fields of the binary, but this has
been long fixed.) Yes, the MULTIBOOT_SYMTAB_SPACE option goes away; yay!
Instead, copy the required data after the kernel in a way that avoids having
to reserve space and use the new ksyms_init_explicit function to avoid the
need to construct a minimal ELF image.
Fixes ksyms when using an "unpatched" GRUB (one that does not contain the
fix to honour the "a.out kludge" for ELF images, even when present) -- i.e.
ddb and lkms. As a side effect, the new code is much clearer to read and
digest.
Closes PR port-i386/32865.
exact address of the symtab and strtab ELF sections contents beforehand.
This will be used in i386's Multiboot code to add the initial kernel ksyms
without having to prepare a minimal ELF image that matches the format
expected by the reguluar ksyms_init function.
This part was reviewed by cube@ and successfully passes a full i386 release
build.

- fix several comments to reality
- clean up the #ifdef NO_VCACHE code slightly
- use call instead of set/jmpl
- remove a couple of unnecessary stores to curlwp
for the disk.
- Add a new function, disk_ioctl(), that does generic disk ioctl handling.
DIOCGDISKINFO is handled here now, and others will be added in the future.
- In the wd driver, fill in the dk_info member of struct disk and use the
new disk_ioctl() function.
Make some "#ifdef DIAGNOSTIC" blocks always compiled in; others
convert to KASSERT() where appropriate.
Add some sanity checks and comments while here.
do not add the offset to the result - the calculated PA is the right

This fixes DMA to kernel stack, and avoids "fabricating a geometry"

After a rmdir()ed directory has been truncated, force an update of
the directory's inode after queuing the dirrem that will decrement
the parent directory's link count. This will force the update of
the parent directory's actual link to actually be scheduled. Without
this change the parent directory's actual link count would not be
updated until ufs_inactive() cleared the inode of the newly removed
directory, which might be deferred indefinitely. ufs_inactive()
will not be called as long as any process holds a reference to the
removed directory, and ufs_inactive() will not clear the inode if
the link count is non-zero, which could be the result of an earlier
system crash.

For me, the good effect is at least that I'm getting less filesystem
inconsistencies after a crash.

getnewvnode() while holding on to any vnode lock deadlocks the
system if the file system is being forcibly unmounted.
Normal file systems don't trigger this problem because of two reaons:
1) they don't hold on to vnode locks while idling who-knows-where, so
the race doesn't trigger
2) they aren't usually unmounted with FORCE; puffs is, in case "someone"
manages to make a crashy userspace server
Nevertheless, a real solution is slowly being braised.

get_ascii gets in the way.
It contains the VFS attachment and userspace message-passing interface.
This work was initially started and completed for Google SoC 2005
and tweaked to work a bit better in the past few weeks. While
being far from complete, it is functional enough to be able and
stable to host a fairly general-purpose in-memory file system in
userspace. Even so, puffs should be considered experimental and
no binary compatibility for interfaces or crash-freedom or zero
security implications should be relied upon just yet.
The GSoC project was mentored by William Studenmund and the final
review for the code was done by Christos.

clean up some non-SMP friendly code from cpu_attach():
- only reset the fpu state on the boot cpu
- don't bother printing "FPU version 0" always
- don't call getver() and ignore the result
- print the UPA id on the first cpu0: line
only print mp_tramp address #ifdef DEBUG.
reset the fpu state in cpu_hatch(), like cpu_attach() does for the boot cpu.
cpu_attach() is now free of SMP-unfriendly code.
- On TX, vge(4) seems to assume that tags are written in little endian.
We already use htole32() to write values into descriptors,
so extra byteswap by htons() is not needed there.
- On RX, vge(4) seems to store tags in network byteorder.
We have to swap byteorder regardless of host's byteorder
(i.e. we have to use bswap16() rather than ntohs())
because we already use le32toh() to read values from descriptors.
Anyway, no need to use htons()/ntohs() because there is no stream data.
