915f34e20c [PATCH] x86_64: Remove useless KDB vector
It was set as an NMI, but the NMI bit always forces an interrupt
to end up at vector 2. So it was never used. Remove.

89b831ef8b [PATCH] x86_64: Support for AMD specific MCE Threshold.
MC4_MISC - DRAM Errors Threshold Register realized under AMD K8 Rev F.
This register is used to count correctable and uncorrectable ECC errors that occur during DRAM read operations.
The user may interface through sysfs files in order to change the threshold configuration.

bank%d/error_count - reads current error count, write to clear.
bank%d/interrupt_enable - set/clear interrupt enable.
bank%d/threshold_limit - read/write the threshold limit.

APIC vector 0xF9 in hw_irq.h.
5 software defined bank ids in mce.h.
new apic.c function to setup threshold apic lvt.
defaults to interrupt off, count enabled, and threshold limit max.
sysfs interface created on /sys/devices/system/threshold.

AK: added some ifdefs to make it compile on UP

d6c7ac081b [PATCH] x86_64 two timer entries in /sys
attached patch renames one instance of
	/sys/devices/system/timer
to
	/sys/devices/system/timer_pit
to avoid a name clash with another instance created in time.c.

a8db2db1e6 [PATCH] introduce setup_timer() helper
Every user of init_timer() also needs to initialize ->function and ->data
fields.  This patch adds a simple setup_timer() helper for that.

The schedule_timeout() is patched as an example of usage.

e5bc8b6baf [PATCH] x86-64: Make remote TLB flush more scalable
Instead of using a global spinlock to protect the state
of the remote TLB flush use a lock and state for each sending CPU.

To tell the receiver where to look for the state use 8 different
call vectors.  Each CPU uses a specific vector to trigger flushes on other
CPUs. Depending on the received vector the target CPUs look into
the right per cpu variable for the flush data.

When the system has more than 8 CPUs they are hashed to the 8 available
vectors. The limited global vector space forces us to this right now.
In future when interrupts are split into per CPU domains this could be
fixed, at the cost of needing more IPIs in flat mode.

Also some minor cleanup in the smp flush code and remove some outdated
debug code.

Requires patch to move cpu_possible_map setup earlier.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
