When trying to verify this patch on our PXA270 system we get the
following error when running an XIP rootfs:

cramfs: checking physical address 0xa00000 for linear cramfs image
cramfs: linear cramfs image appears to be 3236 KB in size
VFS: Mounted root (cramfs filesystem) readonly.
Freeing init memory: 96K
/sbin/init: error while loading shared libraries: libgcc_s.so.1:
failed to map segment from shared object: Error 11
Kernel panic - not syncing: Attempted to kill init!

However, if our busybox binary is XIP while the libgcc_s.so.1 is not
XIP, busybox runs fine.

Richard, May I email you the rootfs tarball so you can recreate what
we are seeing?  It is a little less than 2MiB.  The filing system
executables will only run on a PXA27x processor.
