The "oprofile" user-space tools don't use the kernel OPROFILE support
any more, and haven't in a long time. User-space has been converted to
the perf interfaces.
Also note that ia64 supports oprofile but not perf and profiling
shouldn't be working anyway currently.
Remove the old oprofile's architecture specific support.

There are two EFI RTC drivers, the original drivers/char/efirtc.c
driver and the more modern drivers/rtc/rtc-efi.c.
Both implement the same interface, but the new one does so
in a more portable way.
Move everything over to that one and remove the old one.

The only thing remaining of the machvecs is a few checks if we are
running on an SGI UV system. Replace those with the existing
is_uv_system() check that has been rewritten to simply check the
OEM ID directly.
That leaves us with a generic kernel that is as fast as the previous
DIG/ZX1/UV kernels, but can support all hardware. Support for UV
and the HP SBA IOMMU is now optional based on new config options.

Prompted by a change to drivers/scsi/Kconfig which used to do a
"select NET" but now does a "depends on NET". This meant that some

This has been broken since May 2008 when Al Viro killed altroot support.
Since nobody has complained, it would appear that there are no users of
this code (A plausible theory since the main OSVs that support ia64 prefer
to use the IA32-EL software emulation).

PNP and PNPACPI turned on
i8042 recently changed from ACPI to PNP detection. Without PNP, it
probes legacy I/O ports for the keyboard controller, which causes an
MCA on HP boxes.
Also, I'm about to remove 8250_acpi.c, so we'll need PNP to detect
non-PCI serial ports. Until 8250_acpi.c is removed, some systems
will see serial ports reported twice (once from 8250_acpi.c and again
from 8250_pnp.c). This is harmless.
PNPACPI is still marked EXPERIMENTAL, but I'm not aware of any
outstanding issues on ia64.
IDE_GENERIC turned off (except for SGI simulator, all ia64 IDE is PCI)
ide-generic probes compiled-in legacy I/O ports for IDE devices, which
again causes an MCA. It would be nicer to just get rid of all the
legacy junk from include/asm-ia64/ide.h, but that is a bit riskier
because it could break ide-cs and the HDIO_REGISTER_HWIF ioctl
(http://www.ussg.iu.edu/hypermail/linux/kernel/0508.2/0049.html).
Here's the essence of the patch:
-# CONFIG_PNP is not set
+CONFIG_PNP=y
+CONFIG_PNPACPI=y
-CONFIG_IDE_GENERIC=y
+# CONFIG_IDE_GENERIC is not set
Tested on tiger, bigsur, and zx1.

Build issues were mostly in the ACPI=n case -- don't do that.
Select ACPI from IA64_GENERIC.
Add some missing dependencies on ACPI.

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!
