alpha/include/lock.h: remove nop simplelock macros, which are defined
in <sys/lock.h> if NCPUS == 1.
As a result, NULL_SIMPLELOCK is defined, and a few warnings removed.
2) rename variables to be more conclusive.
3) fix a problem in uhci_ii_done. Avoid collecting all the status's of the
TD's, we only need to one from the last inactive one.
4) Change the errorcount from 2 to 3 (see UHCI spec.).
before mounting (should help to do not mount extended partitions:-).
Fixed problem with hanging while unmounting busy fs.
And (the most important) added some locks to prevent
simulaneous access to kernel structures!
- unifdef -DCOMPAT_IPFW (this was on by default already)
- remove traces of in-kernel ip_nat package, it was never committed.
- Make IPFW and DUMMYNET initialize themselves rather than depend on
compiled-in hooks in ip_init(). This means they initialize the same
way both in-kernel and as kld modules. (IPFW initializes now :-)
Move handling of CAM_AUTOSENSE_FAIL into block dealing with
all other scsi status errors.
cam_queue.c:
cam_queue.h:
Fix 'off by one' heap bug in a more efficient manner. Since
heap algorithms like to deal with indexes started from 1,
offset our heap array pointer at allocation time to make this
so for a C environment. This makes the implementation of the
algorithm a bit more efficient.
cam_xpt.c:
Use macros for accessing the head of the heap so that code
is isolated from implementation details of the heap.
because the act of doing the release kills the hints(!). A quirk of
the wrapper caused it to reset all the settings, except perhaps for the
memory address. I've tested this with a real SMC 8013EPC - which uses
shared memory addresses - it seems to work OK.
Use pmap_TLB_invalidate instead of invltlb_1pg to eliminate
unnecessary IPIs.
pmap_remove, pmap_protect and pmap_remove_pages:
Use pmap_TLB_invalidate_all instead of invltlb to eliminate
unnecessary IPIs.
pmap_copy:
Use cpu_invltlb instead of invltlb when updating APTDpde.
pmap_changebit:
Rather than deleting the unused "set bit" option (which may be
useful later), make pmap_changebit an inline that is used
by the new pmap_clearbit procedure.
Collectively, the first three changes reduce the number of TLB shootdown
IPIs by 1/3 for a kernel compile.
