easier and much less error-prone to just identity map it in the resuming
kernel as we have more control over the VA space layout there (otherwise
we are at the mercy of the suspending kernel's placement of the piglet VA).
This diff also increases the size of the piglet to 4 chunks, to avoid an
overwrite issue seen in m2k14 where the start of the kernel text was
overwritten with a bounced chunk before unpack.

above 1GB physical (caused by using an incorrect page size mask)
Also removes some unneeded low memory mappings on both amd64 and i386 (this
is a cosmetic fix but makes things easier to debug).
|
|
Chunks are now sorted by ascending PA and all chunks are bounced before
unpack. This fixes an issue where the trampoline chunks were being placed
at the end of the unpack ordering, causing overwrite during unpack.

locked by a different thread. Teach lockstatus() to return LK_EXCLUSIVE
if an exclusive lock is held by some other thread.

In other words, ta0-ta3 are now a4-a7 instead of t0-t3; and the former t4-t7
are now t0-t3.

but then parked ourselves in real mode without completing acquisition of
said lock. Also removes the park routine from i386 since we don't need it
(the APs are already parked at the time we start unpack).
discussed with and ok kettenis@, also ok deraadt@

doesnt need to know which ifp an mbuf was allocated on so it can uncount
it on free.
while here, remove the ext_backend field which identifies the pool the
cluster came from and use ext_arg instead.

now that it is a trivial wrapper around the extended bpf_mtap_hdr, we can
use bpf_mtap_hdr directly. added benefit: pflog_bpfcopy doesn't need to
be exported any more and can stay private to if_pflog.c

the various bpf_mtap_* are very similiar, they differ in what (and to some
extent how) they prepend something, and what copy function they pass to
bpf_catchpacket.
use an internal _bpf_mtap as "backend" for bpf_mtap and friends.
extend bpf_mtap_hdr so that it covers all common cases:
if dlen is 0, nothing gets prepended.
copy function can be given, if NULL the default bpf_mcopy is used.
adjust the existing bpf_mtap_hdr users to pass a NULL ptr for the copy fn.
re-implement bpf_mtap_af as simple wrapper for bpf_mtap_hdr.
re-implement bpf_mtap_ether using bpf_map_hdr
re-implement bpf_mtap_pflog as trivial bpf_mtap_hdr wrapper

but I flipped the test on i386/amd64, thus breaking kernel traps before
enough proc0 bits were set up. In theory, this could have resulted in
a NFS read for a page fault being done with a process's old credentials.

page rounding! Disgusting. Instead, define local copies of those
macros.

this inside #ifdef _KERNEL in any case, so nothing really changes.

uvm_extern.h, uvm_param.h, and sysctl.h will no longer gaurantee that
_KERNEL code gets it.

via if_rxring things. this effectively deprecates the third argument
for MCLGETI and m_clget and makes the mbuf layer no longer care about
interfaces and simplifies the allocation paths.
the timeout used to measure livelock has been moved to net/if.c.

to using if_rxr.
cut the reporting systat did over to the rxr ioctl.
tested as much as i can on alpha, amd64, and sparc64.
mpi@ has run it on macppc.

out of the mbuf layer, and break the assumption that an interface will
only have a single ring per mbuf cluster size.
mpi@ is ok with moving this forward

argument to MCLGETI to make that clear.

right value out of the softc. then its assigned the same value again
after the rest of the var decls.
well, it used to be. not after this commit.

entire tx path. if we try to bus_dmamap_load a very fragmented packet
m_defrag it and try again.
this is just like if_bge.c r1.355.
