chs 9672ac098f add a new km flag UVM_KMF_CANFAIL, which causes uvm_km_kmemalloc() to 
return failure if swap is full and there are no free physical pages.
have malloc() use this flag if M_CANFAIL is passed to it.
use M_CANFAIL to allow amap_extend() to fail when memory is scarce.
this should prevent most of the remaining hangs in low-memory situations.

mycroft 30d477000a The entry point address for the interpreter must be adjusted by the text 
section VMA on all platforms.  It just happens to 0 normally on everything but
MIPS.

gehenna fcba53f1a9 fix that no major numbers is assigned dynamically if the 
not-listed-in-majors device switch is loaded.

gehenna 77a6b82b27 Merge the gehenna-devsw branch into the trunk. 
This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

gmcgarry 366dfb04d7 Attempt to protect restartable atomic sequences of a traced process 
being written to.  Breakpoints aren't good in a RAS.  This test isn't
infallible, since we can't protect memory which will be registered
as a RAS in the future.

Also, set the PC before attempting to single-step, so we can backout
from single-stepping.  Just in case we try to single-step into a RAS.

augustss 731d1eccf2 Get rid of sysctl for setting BCM2033 firmware path. It doesn't work 
for ports that don't include files.usb, and it's also not done quite
the way it should.

scw a82718b34d Casting from a pointer, to a db_expr_t, has to go via an intptr_t. 
(db_expr_t == int64_t on sh5, for example).
 2002-08-26 11:34:27 +00:00
scw 41e5042829 Pointers must be cast to {,u}intptr_t before they can be cast to register_t, 
at least on sh5, where sizeof(register_t) != sizeof(void *) in ILP32 mode.

lukem 76f5313c64 in start_init(), if RB_ASKNAME is set in boothowto, ask for the path 
name to start up as init (rather than just cycling thru initpaths[]

behaviour remains.  inspired by changes in der Mouse's patchtree.
