SPARC include problem

SPARC include problem

[Sean Jones]

In compiling 2.4.4-ac5 for my SPARCStation 20, I had an error in the
compile resulting from the inability to find a hw_irq.h in the
include/asm directory. Do you know where I may be able to find such a
file?

Thank you

How did you find this problem if the build couldn't find the
"bzImage" rule? :-)

You don't. I discussed this last week with Russell King: the ARM port
also doesn't have the file hw_irq.h in include/asm-arm. According to
Russell it is only needed in the arch dependent subdirectories, and not
in the drivers.

Any driver that includes linux/irq.h is not written to be portable. The
only generic driver that includes it is driver/pcmcia/hd64465_ss.c, but
on second glance it's a Hitachi HD64465 specific driver anyway.

Re: SPARC include problem

The include error was in kernel/sched.c . Should I rewrite the includes
for this file to include include/asm/irq.h over include/linux/irq.h? I
temporarily bypassed this problem by creating a blank asm/hw_irq.h . 

I also ran into a compile problem in arch/sparc/kernel/sparc_ksyms.c .
The rw semaphores seem to be undeclared. Here are the warnings:

You shouldn't expect to be able to compile the main kernel source on
Sparc at all. See http://www.tux.org/lkml/#s6-6 .
