7e949b63e4 Indicate that env(1) allows you to supply arguments to the utility it
executes in the usage() message and manual page. Use "utility" instead of
"command" in both places to emphasise that shell builtins etc. will not work,
and to be consistent with the terminology used by POSIX.

1419eacb86 Squish the "could sleep with process lock" messages caused by calling
uifind() with a proc lock held.

change_ruid() and change_euid() have been modified to take a uidinfo
structure which will be pre-allocated by callers, they will then
call uihold() on the uidinfo structure so that the caller's logic
is simplified.

This allows one to call uifind() before locking the proc struct and
thereby avoid a potential blocking allocation with the proc lock
held.

This may need revisiting, perhaps keeping a spare uidinfo allocated
per process to handle this situation or re-examining if the proc
lock needs to be held over the entire operation of changing real
or effective user id.

00e1854a1f o Replace GIANT_REQUIRED in vm_object_coalesce() by the acquisition and
release of Giant.
 o Reduce the scope of GIANT_REQUIRED in vm_map_insert().

These changes will enable us to remove the acquisition and release
of Giant from obreak().

d8dbc77c56 Make the speed used by gdb over serial settable in the kernel configuration.
This facilitates the use in circumstances where you are using a serial
console as well. GDB doesn't support anything higher than 9600 baud (19k2
if you are lucky), but the console does.

4741dcbff5 Honor the BUCKETCACHE flag on free as well. 2002-06-17 23:53:58 +00:00
Jeff Roberson
18aa2de5a7 - Introduce the new M_NOVM option which tells uma to only check the currently
allocated slabs and bucket caches for free items.  It will not go ask the vm
  for pages.  This differs from M_NOWAIT in that it not only doesn't block, it
  doesn't even ask.

- Add a new zcreate option ZONE_VM, that sets the BUCKETCACHE zflag.  This
  tells uma that it should only allocate buckets out of the bucket cache, and
  not from the VM.  It does this by using the M_NOVM option to zalloc when
  getting a new bucket.  This is so that the VM doesn't recursively enter
  itself while trying to allocate buckets for vm_map_entry zones.  If there
  are already allocated buckets when we get here we'll still use them but
  otherwise we'll skip it.

- Use the ZONE_VM flag on vm map entries and pv entries on x86.

d8880ad0bd Avoid reprobing on loading a driver. This does not work as the ivars set
during the previous probe are stale.

What really should be done is route the probe through
device_probe_and_attach bit this is one of those ICBBATIASS (I can't be
bothered as there is a simpler solution). The user can easily replug the
device after kldloading a new device driver.

dba3dc7bdc Use OBJDIR instead of CURDIR. This unbreaks loading modules through
'make load' if an object dir was, like it is used in /sys/modules. I.e.

	cd /sys/modules/umass
	make obj
	make
	make load

works again without having to install the module.

If no objdir was used the module in the current directory is used.

3e2ec6ea88 e_pow.c:
Fixed pow(x, y) when x is very close to -1.0 and y is a very large odd
integer.  E.g., pow(-1.0 - pow(2.0, -52.0), 1.0 + pow(2.0, 52.0)) was
0.0 instead of being very close to -exp(1.0).

e_powf.c:
Apply the same patch although it is just cosmetic because odd integers
large enough to cause the problem are too large to be precisely represented
as floats.
