Fernando Luis [** ISO-8859-1 charset **] VázquezCao 70ae77f497 [PATCH] x86-64: Use safe_apic_wait_icr_idle in __send_IPI_dest_field - x86_64
Use safe_apic_wait_icr_idle to check ICR idle bit if the vector is
NMI_VECTOR to avoid potential hangups in the event of crash when kdump
tries to stop the other CPUs.

Fernando Luis [** ISO-8859-1 charset **] VázquezCao 9062d888aa [PATCH] x86-64: __send_IPI_dest_field - x86_64
Implement __send_IPI_dest_field which can be used to send IPIs when the
"destination shorthand" field of the ICR is set to 00 (destination
field). Use it whenever possible.

Jan Beulich 00f1ea6967 [PATCH] x86: adjust inclusion of asm/fixmap.h
Move inclusion of asm/fixmap.h to where it is really used rather than
where it may have been used long ago (requires a few other adjustments
to includes due to previous implicit dependencies).

Andi Kleen 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.

Andi Kleen eddfb4ed29 [PATCH] x86-64: Remove obsolete APIC "write around" bug workaround
No x86-64 chipset has this bug

Generated code doesn't change because it was always disabled.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
