test does not change undefined flag like Cyrix CPUs. Another is that
5/2 test changes undefined flag like Intel CPUs. Latter one could not
be detected and was recognized 486DX CPU. To solve this,
finishidentcpu() calls identblue() when cpu_vendor is null string
(that is, CPUID instruction is not supported) and cpu == CPU_486.
Tests have been done on IBM BlueLightning CPUs, i486SX and i486DX.

- increase the default timeout from 10 seconds to 60 seconds
- add a new kernel option, SCSI_PT_DEFAULT_TIMEOUT, that lets users specify
the default timeout for the pt driver to use
- add two new ioctls, one to get the timeout for a given pt device, the
other to set the timeout for a given pt device. The idea is that
userland applications using the device can set the timeout to suit their
purposes. The ioctls are defined in a new header file, sys/ptio.h

seconds to 1 second. This fixes a problem where gdb would appear to
hang on flaky serial connections. There's a theoretical problem that
the relatively short timeout could cause problems on slow links, but
you can override the default value with the 'set remotetimeout'
command.

o Add the -nat flag and discourage the use of the -alias flag. Both do

to achieve a delay is pretty mean.
Andrew reports:
"The tulip_delay_300ns() is, well, bloody stupid on machines with a
heavily loaded PCI bus. It tries to do a delay by assuming PCI reads
will take a certain amount of time & issues a large amount of
(expensive, 5% CPU when your PCI bus is heavily loaded) pci reads.
Locally, we've replaced the calls to tulip_delay_300ns(sc) in the EMIT
macros with a simple DELAY(1) and not seen any problems. Plus we've
gained about 50Mb/sec throughput on our gigabit network cards because
of the added PCI bus bandwidth available."
Also, I do not understand why, but this change appears to stop the
Transmit Fifo underrun on one of my systems (but not the Alpha PC164SX).
This shouldn't make that much of a difference since the mii bus isn't
touched all that often, but perhaps when it does get accessed and hence
hammers the register, it was causing the chip to get upset.

into two parts - one to do the bsfl and the other to convert the result
(base 0) to ffs()-like (base 1) in inline C. This enables the optimizer
to be a lot smarter in certain cases, like where it knows that the argument
is non-zero and we want ffs(known non zero arg) - 1. This appears to
produce identical code to the old inline when the argument is unknown.
works correctly in if/else etc. egcs had probably picked up most of the
problems here before with "ambiguous braces" etc, but this should
increase the robustness a bit. Based on an idea from Eivind Eklund.
Use an upward approximation of the number of characters required
for decimal representations of uid_t, gid_t and u_quad_t, intead
of arbitrary values that may not be safe in the future.

Extract the next runnable process selection out of cpu_switch() into a
fairly machine independent C routine. gcc actually does a pretty good
