Hi all,
I tried to build linux-next as of 20100201 with omap2plus_defconfig. In addition
I turned on CONFIG_DEBUG_LL and hit the following error.
AS arch/arm/kernel/debug.o
arch/arm/kernel/debug.S: Assembler messages:

Will try and bisect this down later. Just reporting for now.

No need to bisect. Tony knows about it. It's the OMAP debug code using
what was a macro in assembly, which becomes a C function with the dynamic
P2V patches.

Hi Russell,
This appears to be introduced after this commit from you:
8397c0703b5aa99fdb7c4e5177c4e2fc3b97c835 is the first bad commit
commit 8397c0703b5aa99fdb7c4e5177c4e2fc3b97c835
Author: Russell King <rmk+kernel@arm.linux.org.uk>
Date: Tue Jan 4 19:09:43 2011 +0000
ARM: P2V: introduce phys_to_virt/virt_to_phys runtime patching
This idea came from Nicolas, Eric Miao produced an initial version,
which was then rewritten into this.
The build failure seems to be omap-specific; I don't see this when
I build a mx51_defconfig for instance, but I do get a similar error
when building for omap1_defconfig.
I'll try and dig deeper.
Thanks in advance for any pointers.
- Anand

This is known and Russell has already pointed this
out even before patch for dynamic p2v were merged.
OMAP LL debug code needs to be fixed.

Posted a fix for that yesterday. Will upload it into Russell's
patch system for the p2v branch.
