Sanitized kernel headers in linux-headers-2.6.18 don't provide asm/unaligned.h anymore, but reiserfsprogs-3.6.19 still needs it to compile. The attached patch creates a replacement unaligned.h with unaligned 32 bit I/O support for all gentoo supported architecture.
Created attachment 100840 [details, diff] replacement asm/unaligned.h
fixed with 3.6.20, thanks for the report !
since 3.6.20 was pmasked we need this for 3.6.19 now.

Comment on attachment 100840 [details, diff] replacement asm/unaligned.h i didnt add this patch to 3.6.20 because it's wrong 3.6.20 already handled the missing header
backported the fix from 3.6.20
