from both the acpi module build directory and a kernel build directory.
The latter didn't work when one attempted to build a kernel which had
"device acpi" with the "make kernel-toolchain buildkernel" command
because a cross-compiler couldn't find anything in the standard system
include path (it's empty in the kernel-toolchain case).
Fix this by passing a better root path to kernel headers (src/sys)
which works for both cases, kernel and module (-I@ only worked for
module).
Also, while here, pass -nostdinc (and a different spelling for icc) --
it's a feature that the kernel source tree is self-contained, and this
change enforces this.

bad under high load. For example with 40k sockets and 25k tcptw
entries, connect() syscall can run for seconds. Debugging showed
that it iterates the cycle millions times and purges thousands of
tcptw entries at a time.
Besides practical unusability this change is architecturally
wrong. First, in_pcblookup_local() is used in connect() and bind()
syscalls. No stale entries purging shouldn't be done here. Second,
it is a layering violation.
o Return back the tcptw purging cycle to tcp_timer_2msl_tw(),
that was removed in rev. 1.78 by rwatson. The commit log of this
revision tells nothing about the reason cycle was removed. Now
we need this cycle, since major cleaner of stale tcptw structures
is removed.
o Disable probably necessary, but now unused
tcp_twrecycleable() function.

- hold/release device in start/done routines, this will probably slow
down things a bit, but previous code was racy;
- only release device if g_gate_destroy() failed - if it succeeded device
is dead and there is nothing to release;
- various other changes which makes forcible destruction reliable.

any threads to them. However, it still counts those cores as "active but
permanently idle" when calculating system-wide CPUs statistics. It is
incorrect, since it skews statistics quite a bit and creates real problems
for certain types of applications (monitoring applications for example),
by making them believe that the system does have enough idle CPU resources,
while in fact it does not.
Correct the problem by not calling performance counting routines on "disabled"
cores. The cleaner solution would be to just disable APIC timer interrupts on
those cores completely, but ENOTIME here and it is not clear if the
additional complexity really worth minor performance gain.

we can find another way to issue an #error, but using a preprocessed
assembler for that purpose and clobbering libc.a with an empty .o
just for the sake of #error reporting is way too much of a burden.
* Expose functions for setting the "skip file" dev/ino information
* Expose functions for setting/querying the block size on reads
* Correctly propagate errors out of archive_read_close/archive_write_close
* Update manpage with information about new functions
the "device isa" presence out of the opt_isa.h in the kernel
build directory, rather than always assuming its presence.
sparc64 is still special cased and is not affected by this
change.
