Avoids using bus_dmamem_alloc/bus_dmamem_map at interrupt time.
Should fix PRs kern/13924 and kern/13979 from dive@endersgame.net
- while I'm there convert to use ether_ioctl.
XXX: FH chanset should be calculated by FH hop pattern, but BayStack 650 AP
always specify chanset to fixed value 1. The previous code try to this
hack into awi driver, but it is insufficient because the chanset value
in awi driver may change while scan and it may be different from the
value in receiving beacon/probe-response. So we save encoded FH chanset
into channel in 802.11 common bss information for now.
- don't both updating fs->fs_cgrotor, since it's actually not used in
the kernel. from Manuel Bouyer in [kern/3389]
- when examining cylinder groups from startcg to startcg-1 (wrapping
at fs->fs_ncg), there's no need to check startcg at the end as well
as the start...
- highlight in the struct fs declaration that fs_cgrotor is UNUSED
- totally clear a glob buffer before use, because FreeBSD depends on
some of the other fields being cleared (other than just gl_offs)
- in strend(), ensure that the source string isn't too large
- remove unnecessarily complicated sizing of proctitle, since snprintf()
will truncate it anyway
kernels as also ELF ones. Also cleaned up the code a bit and removed a
bunch of errors in the ELF loading code... no wonder it didn't work ! ... I
tried to squeeze about 8000 bytes in one 4096 byte page resulting in a
corrupted bss.
called via a callout, kick the completion thread to run it for us (uses
a new flag, SCSIPI_CHAN_KICK).
If we've received BUSY status and we haven't started the completion
thread yet, don't freeze do a callout to scsipi_periph_timed_thaw which
then will try and kick the completion thread- instead treat the command
as if it were a polled command and just call delay for 1 second.
If DIAGNOSTIC is defined, and the periph qfreeze count is less than
zero, panic because some HBA has corrupted the periph structure's
accounting.
