Re-implement smp_send_nmi_allbutself() so that calls to smp_processor_id
(through send_IPI_allbutself) can be replaced with safe_smp_processor_id

This is a the first of a series of patch-sets aiming at making kdump more
robust against stack overflows.
This patch set does the following:
* Add safe_smp_processor_id function to i386 architecture (this function was
inspired by the x86_64 function of the same name).
* Substitute "smp_processor_id" with the stack overflow-safe
"safe_smp_processor_id" in the reboot path to the second kernel.
This patch:
On the event of a stack overflow critical data that usually resides at the
bottom of the stack is likely to be stomped and, consequently, its use should
be avoided.
In particular, in the i386 and IA64 architectures the macro smp_processor_id
ultimately makes use of the "cpu" member of struct thread_info which resides
at the bottom of the stack. x86_64, on the other hand, is not affected by
this problem because it benefits from the use of the PDA infrastructure.
To circumvent this problem I suggest implementing "safe_smp_processor_id()"
(it already exists in x86_64) for i386 and IA64 and use it as a replacement
for smp_processor_id in the reboot path to the dump capture kernel. This is a
possible implementation for i386.

With 2.6.18-rc4-mm2, now wall_jiffies will always be the same as jiffies.
So we can kill wall_jiffies completely.
This is just a cleanup and logically should not change any real behavior
except for one thing: RTC updating code in (old) ppc and xtensa use a
condition "jiffies - wall_jiffies == 1". This condition is never met so I
suppose it is just a bug. I just remove that condition only instead of
kill the whole "if" block.

ppc can boot one single binary on prep, chrp and pmac boards. ppc64 can
boot one single binary on pseries and G5 boards. pmac has no legacy io,
probing for PC style legacy hardware (or accessing the legacy io area
regulary) may lead to a hard crash:
* add check for parport_pc, exit on pmac. 32bit chrp has no
->check_legacy_ioport, the probe is always called. 64bit chrp has
check_legacy_ioport, check for a "parallel" node
* add check for isapnp, only PReP boards may have real ISA slots. 32bit
PReP will have no ->check_legacy_ioport, the probe is always called.
* update code in i8042_platform_init. Run ->check_legacy_ioport first,
always call request_region. No functional change. Remove whitespace
before i8042_reset init.

In cases where the acpi memory-add event does not containe the pxm (node)
infomation allow the driver to look up node info based on the address. The
acpi_get_node call returns -1 if it can't decode the pxm info, this causes
add_memory to panic. acpi_get_node would have to decode the resource from the
handle (a lenghty proposition). This seems to be the cleanist point to
interject the hook.

After Christophs SCSI change, the only usage left is RQ_ACTIVE
and RQ_INACTIVE. The block layer sets RQ_INACTIVE right before freeing
the request, so any check for RQ_INACTIVE in a driver is a bug and
indicates use-after-free.
So kill/clean the remaining users, straight forward.

[AK: This apparently broke some systems, but we need it to fix
a compile problem with old binutils and in theory the patch
is correct. So let's trying reenabling it again.]
o Currently bss segment is being placed somewhere in the middle (after .data)
section and after bss lots of init section and data sections are coming.
Is it intentional?
o One side affect of placing bss in the middle is that objcopy keeps the
bss in raw binary image (vmlinux.bin) hence unnecessarily increasing
the size of raw binary image. (In my case ~600K). It also increases
the size of generated bzImage, though the increase is very small
(896 bytes), probably a very high compression ratio for stream
of zeros.
o This patch moves the bss at the end hence reducing the size of
bzImage by 896 bytes and size of vmlinux.bin by 600K.
o This change benefits in the context of relocatable kernel patches. If
kernel bss is not part of compressed data (vmlinux.bin) then it does
not have to be decompressed and this area can be used by the decompressor
for its execution hence keeping the memory requirements bounded and
decompressor code does not stomp over any other data loaded beyond
kernel image (As might be the case with bootloaders like kexec).

Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390
timer interrupt handler with this change.
Currently update_times() calculates ticks by "jiffies - wall_jiffies", but
callers of do_timer() should know how many ticks to update. Passing ticks
get rid of this redundant calculation. Also there are another redundancy
pointed out by Martin Schwidefsky.
This cleanup make a barrier added by
5aee405c662ca644980c184774277fc6d0769a84 needless. So this patch removes
it.
As a bonus, this cleanup make wall_jiffies can be removed easily, since now
wall_jiffies is always synced with jiffies. (This patch does not really
remove wall_jiffies. It would be another cleanup patch)

This is an updated version of Eric Biederman's is_init() patch.
(http://lkml.org/lkml/2006/2/6/280). It applies cleanly to 2.6.18-rc3 and
replaces a few more instances of ->pid == 1 with is_init().
Further, is_init() checks pid and thus removes dependency on Eric's other
patches for now.
Eric's original description:
There are a lot of places in the kernel where we test for init
because we give it special properties. Most significantly init
must not die. This results in code all over the kernel test
->pid == 1.
Introduce is_init to capture this case.
With multiple pid spaces for all of the cases affected we are
looking for only the first process on the system, not some other
process that has pid == 1.

This appears to be the only usage of is_init in the kernel besides the
usage in sched.h. On ia64 the same function is called in_init. So to
remove the conflict and make the kernel more consistent rename is_init
is_core is_local and is_local_section to in_init in_core in_local and
in_local_section respectively.
Thanks to Adrian Bunk who spotted this, and to Matthew Wilcox
who suggested this fix.

As suggested by Muli Ben-Yehuda this function is moved to generic code as
may be useful for all archs.

efi_call_phys_epilog
The functions efi_call_phys_prelog and efi_call_phys_epilog in
arch/i386/kernel/efi.c wrap the spinlock efi_rt_lock: efi_call_phys_prelog
returns with the lock held, and efi_call_phys_epilog releases the lock
without acquiring it. Add lock annotations to these two functions so that
sparse can check callers for lock pairing, and so that sparse will not
complain about these functions since they intentionally use locks in this
manner.
