Subject: linux-next: rr tree build failure

Hi Rusty,

Today's linux-next build (powerpc ppc44x_defconfig) failed like this:

.tmp_exports-asm.o: In function `__ksymtab_pci_alloc_consistent':
(__ksymtab_sorted+0x2a30): undefined reference to `pci_alloc_consistent'
.tmp_exports-asm.o: In function `__ksymtab_pci_free_consistent':
(__ksymtab_sorted+0x2b70): undefined reference to `pci_free_consistent'

Caused by the powerpc architecture EXPORTing static inlines (for 32 bit
builds) interacting with changes in the rr tree.

I have applied this patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Thu, 12 Nov 2009 18:54:13 +1100
Subject: [PATCH] powerpc: do not export pci_alloc/free_consistent

Since they are static inline functions.
