Removes a few pointless register keywords. register is merely a compiler
hint that access to the variable should be optimized, but gcc (3.3.6 in my
case) generates the exact same code with and without the keyword, and even
if gcc did something different with register present I think it is doubtful
we would want to optimize access to these variables - especially since this
is generic library code and there are supposed to be optimized versions in
asm/ for anything that really matters speed wise.
(akpm: iirc, keyword register is a gcc no-op unless using -O0)

The only call to ide_cdrom_capacity is in code protected by
CONFIG_PROC_FS, so when that is not enabled, the compiler complains:

task_struct is an internal structure to the kernel with a lot of good
information, that is probably interesting in core dumps. However there is
no way for user space to know what format that information is in making it
useless.
I grepped the GDB 6.3 source code and NT_TASKSTRUCT while defined is not
used anywhere else. So I would be surprised if anyone notices it is
missing.
In addition exporting kernel pointers to all the interesting kernel data
structures sounds like the very definition of an information leak. I
haven't a clue what someone with evil intentions could do with that
information, but in any attack against the kernel it looks like this is the
perfect tool for aiming that attack.
So since NT_TASKSTRUCT is useless as currently defined and is potentially
dangerous, let's just not export it.
(akpm: Daniel Jacobowitz <dan@debian.org> "would be amazed" if anything was
using NT_TASKSTRUCT).

else

I just noted that -mtune is used, which is only supported on recent GCCs; by
reading http://gcc.gnu.org/gcc-3.4/changes.html, you see "-mcpu has been
renamed to -mtune.", so for GCC < 3.4 we're not using any specific tuning in
the appropriate cases. However -mcpu is deprecated, so use -mtune when
possible.
This was introduced by commit e9d4dce954a60dc23dd1d967766ca2347b780e54 of the
old tree (between 2.6.10-rc3 and 2.6.10) by Linus Torvalds, to remove the use
of -march, since that could trigger gcc using SSE on its own. But no
attention was used about using -mcpu vs. -mtune.
And btw, the old 2.6.4 code (for instance) was:
cflags-$(CONFIG_MPENTIUMII) += $(call check_gcc,-march=pentium2,-march=i686)
cflags-$(CONFIG_MPENTIUMIII) += $(call check_gcc,-march=pentium3,-march=i686)
cflags-$(CONFIG_MPENTIUMM) += $(call check_gcc,-march=pentium3,-march=i686)

Make UML share the underlying cpu-specific tuning done on i386.
Actually, for now many config options aren't used a lot - but that can be done
later. Also, UML relies on GCC optimization for things like memcpy and such
more than i386, so specifying the correct -march and -mtune should be enough.
Later, we may want to correct some other stuff.
For instance, since FPU context switching, for us, is done (at least
partially, i.e. between our kernelspace and userspace) by the host, we may
allow usage of FPU operations by GCC. This doesn't hold for kernelspace vs.
kernelspace, but we don't support preemption.

cpufreq entries in sysfs should only be populated when CPU is online state.
When we either boot with maxcpus=x and then boot the other cpus by echoing
to sysfs online file, these entries should be created and destroyed when
CPU_DEAD is notified. Same treatement as cache entries under sysfs.
We place the processor in the lowest frequency, so hw managed P-State
transitions can still work on the other threads to save power.
Primary goal was to just make these directories appear/disapper dynamically.
There is one in this patch i had to do, which i really dont like myself but
probably best if someone handling the cpufreq infrastructure could give
this code right treatment if this is not acceptable. I guess its probably
good for the first cut.
- Converting lock_cpu_hotplug()/unlock_cpu_hotplug() to disable/enable preempt.
The locking was smack in the middle of the notification path, when the
hotplug is already holding the lock. I tried another solution to avoid this
so avoid taking locks if we know we are from notification path. The solution
was getting very ugly and i decided this was probably good for this iteration
until someone who understands cpufreq could do a better job than me.

Some modules creating sysfs entries under /sys/devices/system/cpu/cpuX/
need to know the parent sysfs entry to make devices under them. This will
just return the sysfs entry for a given cpu.
sysfs entries showing under each cpu sysfs can be easily created if such
entries can be created by registering a sysfs driver for cpuclass. The
issue is when the entry is created the CPU may not be online, hence we
would need to defer the creation until the online notification comes.

o This should not have failed because before calling setup_local_APIC(), it is
ensured that even if BIOS has not reported boot cpu, then hard set the
prence of it. Problem happens because of usage of hard_smp_processor_id()
which is hardcoded to zero in case of non SMP kernel. In kdump case second
kernel can boot on a cpu whose boot cpu id is not zero.
