[bug] 2.6.39-rc3 fails to boot on Alpha

[Mikael Pettersson]

2.6.39-rc3 doesn't boot on my Alpha (XP900).  As soon as aboot has loaded
and started the kernel I get:

halted CPU 0

halt code = 4
invalid PTBR
PC = fffffc00003130d0

(that PC value points to an "lda" instruction in sys_osf_proplist_syscall)

There's no other output except this, so I don't think the kernel got very far.

Haven't checked 2.6.39-rc[12] or bisected anything yet, but 2.6.38 works fine.

Try replacing the reference to "no_irq_chip" with "dummy_irq_chip"
in arch/alpha/irq_alpha.c: int_rtc_irq().

For me, it was dying in the first RTC interrupt taken.

2.6.39-rc3 booted fine with that change.

At least -rc2 broken also per previous report.  Didn't see any replies
to the initial bug report, so it's not surprising a fix didn't make it
into -rc3.
