I broke this earlier when moving the patch from i386 to x86-64.
Need to return the virtual address here, not the physical address.
This fixes some boot time crashes on x86-64.Cc: gregkh@suse.de

attached patch is 2 more cases i found via running the reference_init.pl
script. These were easy to spot just knowing the file names. There is
one another about init/main.c that i cant exactly zero in. (partly
because i dont know how to interpret the data thats spewed out of the tool).Signed-off-by: Ashok Raj

Currently, x86_64 and ia64 arches do not clear the corresponding bits
in the node's cpumask when a cpu goes down or cpu bring up is cancelled.
This is buggy since there are pieces of common code where the cpumask is
checked in the cpu down code path to decide on things (like in the slab
down path). PPC does the right thing, but x86_64 and ia64 don't (This
was the reason Sonny hit upon a slab bug during cpu offline on ppc and
could not reproduce on other arches). This patch fixes it for x86_64.
I won't attempt ia64 as I cannot test it.Credit for spotting this should go to Alok.

They cause quite bad performance regressions on Netburst
This is temporary until we can get new optimized functions
for these CPUs.This undoes changes that were done in 2.6.15 and in 2.6.16-rc1,
essentially bringing the code back to 2.6.14 level. Only change
is I renamed the X86_FEATURE_K8_C flag to X86_FEATURE_REP_GOOD
and fixed the check for the flag and also fixed some comments.Signed-off-by: Andi Kleen

At resume time, TSC's value or something similar might be changed a lot
against suspend time. This could make system gets a very big lost ticks.

They all have problems with IRQ 0 routing, so just use the APIC on them.
Can be overwritten with "noapicmaintimer"
Signed-off-by: Andi Kleen
Signed-off-by: Linus Torvalds -
Another piece from the no-idle-tick patch.
This can be enabled with the "apicmaintimer" option.
This is mainly useful when the PIT/HPET interrupt is unreliable.
Note there are some systems that are known to stop the APIC
timer in C3. For those it will never work, but this case
should be automatically detected.It also only works with PM timer right now. When HPET is used
the way the main timer handler computes the delay doesn't work.It should be a bit more efficient because there is one less
regular interrupt to process on the boot processor.Requires earlier bugfix from Venkatesh
