kernel, but gcc provides a pessimal builtin for it.
Makefile.i386:
Added a variable (CONF_CFLAGS) for configuration-specific compiler flags.
LINT:
Use CONF_CFLAGS to inhibit use of gcc builtins.
${LIB} was wrong at dependency-parsing time, so dependencies for
libgcc_r*.a were wrong. This somehow worked right, except libgcc_r*.a
were always out of date.
* In the absence of the env vars TMPDIR, TMP, TEMP (which override this
ordering), attempt to create temperary files in /tmp, P_tmpdir (/var/tmp),
/usr/tmp, and . until successful.
and add a config option that allows one to default to 1FM@EOD for tapes
otherwise unquirked or unknown as to which to prefer. Note that tcopy
will be broken for these tapes until tcopy is fixed.
Add debuging for all failure cases in aha_cmd().
Always check DATAIN_REG_READY even if we're ready to exit the
read loop.
The last fix allows the AHA-1640 MCA SCSI adapter to operate
correctly and likely fixes problems on a few other oddball
adapters. (I suspect my Dell Drive Array in 1540 mode needs this.)

apm_saver uses the apm_display() routine from the apm system to
"suspend" the "display" part of the machine.
This is beneficial for some laptops (or other machines with
non-traditional displays) that choke on the 'green' saver's
effect.
Another way of looking at this is that it's the same as a screen
saver that does an 'apm -d 0' to blank the display and an 'apm -d 1'
to bring it back. One probably ought to use these commands to make
sure the effect will be correct before using it unattended.
1. Break out the definition of the soft state structure into an include
file.
2. un-static the soft state and apm_display(), and group them under a
comment that notes the dependency.
For unknown devices the output will now be
pci0: unknown card (vendor=0x109e, dev=0x0878) at 14.1 irq 19
instead of
pci0: unknown card DD^0878 (vendor=0x109e, dev=0x0878) at 14.1 irq 19
Before this change, the code used to take the PCI vendor id and translate it
into a three letter ASCII name.
For PnP devices, the vendor id _does_ map to a nice ASCII name
(eg Creative Labs PnP ID maps to "CTL", ESS PnP ID maps to "ESS")
But there is no such mapping for PCI devices, as can be seen by the
example above where the Brooktree PCI vendor ID maps to "DD^"
The PCI Special Interest Group confirmed they do not have any mappings
from vendor ID to ASCII.
of the number of times a particular type has been used. It's rather easy
to overflow. One site I'm looking at seems to do it in a matter of days.
On the Alpha this is a no-op since 'long' is 64 bit already. The sole
user of this interface seems to be vmstat -m and friends which will need
a recompile. The overheads of using a 64 bit int should be pretty light
as the kernel just does "calls++" type operations and that's it.
