8184d5dc03 Don't pull in the whole uvm(9) API to access only PAGE_SIZE and 
some other constants.  These are provided by sys/param.h now.

8f7318d794 Fix confusion about PRE/POST in previous; and another place that has the 
same issue. Also add a BUS_DMASYNC_POSTWRITE to the POLL operation.
Problem pointed out by tsutsui@.
Still not perfect (a BUS_DMASYNC_PREREAD would be needed after the
testing the condition in the POLL() macro), but closer.

80f97b6e05 Fix bus_dmamap_sync(): it should be a BUS_DMASYNC_POSTWRITE after 
writing to DMA memory.

40cf6f3659 Remove uarea swap-out functionality: 
- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code.  Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.

Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

Discussed on <tech-kern>, reviewed by <ad>.

f60765db47 Use the physical address from the bus_dmamap_load() map, not the one from 
the bus_dmamem_alloc().  Fixes iop(4) on alpha, and possibly sparc64 as
described in the thread

82bb1c2ff8 Add a flags argument to the ld(4) flush handlers, and call these with a 
"poll" flag when called from ld_shutdown().

This is the infrastructure part of kern/38655 - in itself it doesn't
fix the panic referenced in that PR.

XXX: At least ld_twa.c and perhaps ld_iop.c and ld_icp.c need to
check for this new poll flag and do something useful.

e071d39c84 - Convert hashinit() to use kmem_alloc(). The hash tables can be large 
and it's better to not have them in kmem_map.
- Convert a couple of minor items along the way to kmem_alloc().
- Fix some memory leaks.

6127f4ed3f Don't get under the device_t abstraction by measuring the length 
of dv_xname, especially not to set the length of a buffer that
(apparently) belongs to the kernel ABI.  Instead, set the buffer
length to 16, which is the current length of dv_xname.

eb171eaaa7 It's not a good idea for device drivers to modify b_flags, as they don't 
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.
