[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.
