linux-next: sparc build failure

Hi Dave,

Today's linux-next build (sparc allmodconfig) fails like this:

Seems to have been introduced by commit
28e6103665301ce60634e8a77f0b657c6cc099de ("sparc: Fix debugger syscall
restart interactions") which went into Linus' tree recently ("bool" seems
to be missing a definition).

Fixed in current sparc-2.6.git

ok - but was still worth fixing as a general principle: if something 
like nr_irqs is exported in kernel/irq/manage.c then it should be 
exported in non-genirq architectures as well.

Thanks, saves me writing the patch :-)

Actually, it appears that s390 allmodconfig doesn't build any modules
that require nr_irqs.

thanks - the patch below should fix all those architectures. (there's 
also s390)

Subject: [PATCH] sparseirq: export nr_irqs on m68k/sparc/s390

Stephen Rothwell reported such build failures on m68k/sparc/s390:

export nr_irqs on these architectures too.

linux-next: sparc build failure

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 482 bytes --]

Hi Dave,

The sparc32 allmodconfig build of linux-next (next-20080827) failed like
this (among other things):

ERROR: "nr_irqs" [drivers/net/hamradio/baycom_ser_fdx.ko] undefined!
ERROR: "nr_irqs" [drivers/net/3c59x.ko] undefined!

Introduced by the sparseirq tree.

nr_irqs is not exported for sparc.  I will add a patch to add the export
to linux-next today.
