... and with that all instances in arch/x86_64 are gone.

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Also some minor cleanup in the smp flush code and remove some outdated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

I thought I'm done with fixing u32 vs. pm_message_t ... unfortunately that
turned out not to be the case... Here are fixes x86-64.

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!
