[IA64] Update default configs
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.
