Just reporting for now. > Hi Russell, This appears to be introduced after this commit from you: 8397c0703b5aa99fdb7c4e5177c4e2fc3b97c835 is the first bad commit commit 8397c0703b5aa99fdb7c4e5177c4e2fc3b97c835 Author: Russell King 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
