with a class, rather than all aspects of the class when switching
classes for an inetd service. Because we hard-code /daemon in the
current inetd implementation, using SETALL has unfortunate side-effects
involving the MAC code, and potentially other credential related
settings in the future. This change maintains the DoS-resistent
aspects of the class behavior, which is all that is promised in the
inetd man page.
A larger set of diffs providing more pluggability and configurability
was deferred for this more simple approach in the short term.

print_AMD_foo() functions.
- Add a brand name table for the brand index provided on Intel CPU's in
%ebx after cpuid 1.
- For Intel CPUs, if we don't get a processor name from the extended cpuid
then use the brand index in cpuid_cpuinfo to pick a name from the brand
table and copy that name into cpu_brand.
- Replace the duplicated code to use the extended cpuid to replace
cpu_model with the processor name in the AMD and Transmeta sections of
printcpuinfo() with generic code that replaces cpu_model with
cpu_brand if cpu_brand is not an empty string. We also trim leading
spaces from cpu_brand prior to doing this since at least some processor
names (notably those of Intel CPUs) have leading spaces in the name.
- Give print_AMD_features() its own private regs[] array since
printcpuinfo() doesn't use the one it has anymore.
returned from cpuid 0x80000000.
- Add a cpu_brand char array to hold the processor name returned by
cpuid 0x80000002-0x80000004 on AMD, Intel, Transmeta, and possibly
other CPUs.
- Use cpuid to set cpu_exthigh and read the processor name if it is present
in identify_cpu().

because the former segfaults on an ia64 since there is no prototype
for strdup() in strings.h. Converting an "int" to a pointer is fatal.
The corresponding warning has been ignored for ages:
prepend_args.c:75: warning: initialization makes pointer from integer
without a cast
This is fatal on ia64. You cannot convert an implicit int return from
an undeclared function to a pointer as you've lost the upper 32 bits.
On ia64, the warning is "pointer from different sized integer".

in the mptable. The way this works is that we determine if the system
has hyperthreading and how many logical CPU's should be in each physical
CPU by using the information returned by cpuid. During the first pass of
the mptable, we build a bitmask of the APIC IDs of the CPUs listed in the
mptable. We then scan that bitmask to see if the CPUs are already listed
by the mptable, or if there are any APIC IDs already in use that would
conflict with the APIC IDs of the logical CPUs. If that test succeeds,
then we fixup the count of application processors. Later on during the
second pass of the mptable we create fake processor entries for logical
CPUs and add them to the system.
We only need this type of fixup hack when using the mptable to enumerate
CPUs. The ACPI MADT table properly enumerates all logical CPUs.
so that entities that want to use the post_sync hook to write stuff
to devices and other tidy-up can do so before the device tree is
shot down. eg: da doing a SYNC_CACHE etc. This should get crashdumps
working on mpt devices again, and stops the ia64 boxes locking up
on regular shutdown when da tries to issue the scsi commands to mpt.

repeatedly truncate the same file. Each time the file is truncated,
a buffer is grabbed to store the indirect block numbers that need
to be freed. Those blocks cannot be freed until the inode claiming
them is written to disk. Thus, the number of buffers being held by
soft updates explodes and in extreme cases can run the kernel out
of buffers. The problem can be avoided by doing an fsync on the
file every debug.maxindirdep truncates (currently defaulted to 50).
The fsync causes the inode to be written so that the held buffers
can be freed. The check for excessive buffers is checked as part
of the existing hook for excessive dependencies (softdep_slowdown)
in the truncate code.

so it's value is not sign extended when assigned to the uintmax_t variable
used internally by printf. For example, if bit 31 is set in the cpuid
feature word, then %b would print out the initial value as a 16 character
hexadecimal value. Now it only prints out an 8 character value.
