arm: Remaining issue with alignment of __log_buf in printk.c

[Jonathan Cameron]

Hi All,

My stargate 2 board refused to start and after bisection I ended
up at the same patch that Stephen found an alignment issue in.
Unfortunately Stephen's patch doesn't seem to have fixed the
issue for me.
https://lkml.org/lkml/2012/5/10/510 is the thread.  Patch from
Stephen is : f8450fca6ecdea38b5a882fdf6cd097e3ec8651c

Increasing the alignement for 32 bit systems to 8 seems to do the
job but I can't immediately think why...

System is a pxa27x strong arm.

Tree was effectively today's mainline.

Saddly I have too many other bits to fit in today for futher
investigation (hence this information free email!)
