tsleep() instead of DELAY. Also, keep trying flushing buffers when the
number of dirty buffers decreases (20 rounds may not be enouth for a
very large buffer cache).
Using tsleep instead of delay gives a chance to others kernel threads to run,
which is needed for raidframe. With this change I've not been able to
reproduce the 'dirty buffer not flushed' problem with raidframe.
with the following modifications to the initial patch:
- rename SHOLD and P_HOST to SSUSPEND and P_SUSPEND to avoid confusion with
PHOLD()
- don't deal with SSUSPEND/P_SUSPEND in fork1(), if we come here while
scheduler is suspended we're forking proc0, which can't have P_SUSPEND set.
sched_suspend() suspends the scheduling of users process, by removing all
processes from the run queues and changing their state from SRUN to
SSUSPEND. Also mark all user process but curproc P_SUSPEND.
When a process has to be put in SRUN and is marked P_SUSPEND, it's placed in
the SSUSPEND state instead.
sched_resume() places all SSUSPEND processes back in SRUN, clear the P_SUSPEND
flag.
- move CPP_PREDEFINES to netbsd-elf-common.h
- define CPP_SUBTARGET_SPEC to -D__sparc64__
- copy and modify many SPARC_BI_ARCH `specs' from <sparc/sol2-sld-64.h>.
these currently look for 32 bit things in /emul/netbsd32, but this is
temporary
with these changes, i can succesfully build working 32 bit binaries on
a 64 bit system, as long as libgcc, *crt*.o and necessary libraries
exist under /emul/netbsd32.
correctly for the "tp:" case (family iso). To avoid serious code
space bloat, stats are now table-driven.
A side-effect is that the mbuf chain statistics have been slightly re-ordered
to follow the 3 lines of EOT stats (still under Miscellaneous) rather
than sandwiched between "dec bits" and the EOTs.
- use u_int32_t for 32bit quantity unsigned integer type.
- s/unsigned long/BF_LONG/ (BF_LONG = u_int32_t) where appropriate.
- prototype cleanup - due to *BSD code sharing, we still are using __P().

* If etc/localtime can't be readlink(3)'d, assume the default time zone is
UTC
* if errors occur (malloc, fts_open, fts_read, menu generation fails),
skip timezone setting instead of terminating sysinst.
issueing a 'DIOCGPART' at every read. Avoid re-reading the label at
every format-verify (or read/write on the block-device) by fetching the label
at open-time and caching it until we close.

Change stackgap_alloc to bounds-check the allocation vs. the stack
gap, returning NULL if there isn't room for the allocation.
Change emul_find() to check for a NULL return from stackgap_alloc()
and convert that into ENAMETOOLONG.
Reorder various emulation syscalls so that all *_CHECK_ALT_{EXIST,CREAT}
calls (which turn into emul_find() under the covers come *after* small,
fixed-size stackgap_alloc() calls.
Clean up ibcs2 {get,set}groups.
