Thanks - installed.

While building latest git tree I see several 'funny' errors.
  LD      kernel/built-in.o
bfin-linux-uclibc-ld: Warning: size of symbol `_sys_futex' changed from 4 in kernel/sys_ni.o to 262 in kernel/futex.o

bfin-linux-uclibc-ld: Warning: size of symbol `_sys_setreuid16' changed from 4 in kernel/sys_ni.o to 26 in kernel/uid16.o
...

and later:

  LD      .tmp_vmlinux1
bfin-linux-uclibc-ld: Warning: size of symbol `_sys_mremap' changed from 4 in kernel/built-in.o to 82 in mm/built-in.o

bfin-linux-uclibc-ld: Warning: size of symbol `_sys_timerfd' changed from 4 in kernel/built-in.o to 346 in fs/built-in.o
bfin-linux-uclibc-ld: Warning: size of symbol `_sys_ioprio_get' changed from 4 in kernel/built-in.o to 344 in fs/built-in.o

I did not look into these. I assume it is a toolchain issue??

PS. I had to fix a few things to get so far but as I did not do
it the right way I have no patch.
