[PARISC] kernel 2.5.58 doesn't compile

[PARISC] kernel 2.5.58 doesn't compile

[Rolf Eike Beer]

First problem:

arch/parisc/kernel/irq.c: In function `show_interrupts':
arch/parisc/kernel/irq.c:254: subscripted value is neither array nor pointer
arch/parisc/kernel/irq.c: In function `do_irq':
arch/parisc/kernel/irq.c:391: subscripted value is neither array nor pointer

I hope this fixes this, I looked on the other arch's irq.c and did the
following patch. But be careful, this is just looking 10 lines of code up and
down. It is completely untested!

At least it compiles. But then this happens:

arch/parisc/kernel/module.c: In function `apply_relocate_add':

I've grepped a lot, but there are no definitions of this anywhere in the
kernel source. The only ones I found are in a libc header file modified by
Eric Biederman and included in kexec-tools. But they also do not define
R_PARISC_PLABEL32. Looks like anyone missed a file, module.c is new
in 2.5.5?.

[James Bottomley]

The vanilla linux kernel doesn't compile for PA-RISC.  This is because, like 
most non-x86 archs, development is done in a source repository stored 
elsewhere and sync'd with the main trunk at appropriate times.

You need the patches from

http://ftp.parisc-linux.org/2.5/kernel-src/

There's also FAQs and Mailing lists appropriate to PA-RISC at
