ACPI finally works now.

SPARC was unconditionally setting CONFIG_SERIAL_CORE_CONSOLE to y
and conditionally setting CONFIG_SERIAL_CORE depending on the Sparc
sub-drivers.  In addition, the core serial driver for SPARC is
always built, so we end up with link errors.

We instead make CONFIG_SERIAL_CORE{,_CONSOLE} dependent on building
the SPARC core driver (CONFIG_SERIAL_SUNCORE).

with attribute unused.

variables in #if RTC_IRQ.

  warning: right shift count >= width of type
by casting to long before shifting by HIGH_BITS_OFFSET.

  warning: long int format, different type arg (arg 5)
by casting ino_t arguments to unsigned long for printf formats.
In some instances, change %ld to %lu.

Problem: if another CPU is using lazy-TLB, the LDT flushing won't flush
the other CPU's LDT entry.

Fix: use active_mm instead of mm for the flush IPI.

we should allow read-write accesses - it's used for control, not
data.

Not perfectly clean yet, but uses the standard way to descend into subdirs
and gives me working vmlinux and linux targets without spurious rebuilds.

Fix buggy #if removal in iphase.c that crept in with the initcalls fixup.

This is the initial port of InterMezzo for 2.5.  It now compiles,
mounts, and completes I/Os successfully, but we are aware that more
needs to be done and we will do it as quickly as possible.

The timer-handling split patch moved cpufreq stuff from time.c to
timers/timer_tsc.c but not the corresponding #include <linux/cpufreq.h>
causing the build to fail.

The fix is simple.

Convert the tty_drivers list to use list_heads instead of open coded
doubly-linked lists.

Correct compiler warnings for 64 bit platforms and minor formatting cleanup and remove debug function that was causing a conflict with a function of the same name in SCSI
