Fix the HPMC exception handler so that, if we're running on a PA-RISC
2.0 machine, we use the 64-bit PIM data structures.
There was also a bug in the HPMC exception handler that stopped output
being written to the console after we'd taken the exception. We need
to make a PDC_IO pdc call to reset I/O.
this fixes the following deadlock.
a thread doing getcleanvnode:
pick a vnode
acqure v_interlock
v_usecount++
call vclean
now, another thread doing cache_lookup:
picks the vnode
vtryget succeed
vn_lock succeed
now in vclean:
set VI_XLOCK (too late to be noticed by the competing thread)
wait on the vnode lock (this might violate locking order)
the use of a flag bit was suggested by Andrew Doran. PR/41374.
and remove bogus casts around ahc_detach().
XXX: There is a pmf_device_deregister(9) call in ahc_detach()
XXX: while there is no pmf_device_register(9) in ahc_attach().
XXX: It looks more pmf(9) stuff is required for cardbus detach.
unsigned or not - just use a single character itself
+ misc cleanup
+ rename cinfo to "output" and ops_createinfo_t to "ops_output_t" to
be a bit more descriptive
+ shorten some long names
+ get rid of test for libgen.h - it's not needed anymore
+ bump to version 0.99.4, and 20090515 sources, regenerate configure and co
+ numerous name changes to be more consistent and more concise
+ add verbosity level to the variables that can be set and retrieved by
netpgp_setvar() and netpgp_getvar()
+ added --verbose option to netpgp(1)
+ add __RCSID() to all files
- some KNF
- u_intNN_t -> uintNN_t
- wrap long lines and fix indent
- remove return statements at the end of void functions
- use __arraycount()
XXX: many inconsistent aprint_error_dev(9) vs printf(9)
instead. If the detach is forced, do what wdclose() does on the
last close: flush the cache, clear the flag WDF_LOADED, and delete
our reference to the ATA bus device.
XXX This should be done as part of an overall plan to support
power management and device detachment. However, in order to do
that, I would first have to invent sbus_intr_disestablish(). This
is being done at this time in order to aid in the effort to eliminate
shutdownhook_establish().
