Merge branch 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm

Pull ARM fixes from Russell King:
 "A few more ARM fixes:

   - the assembly backtrace code suffers problems with the new printk()
     implementation which assumes that kernel messages without KERN_CONT
     should have newlines inserted between them. Fix this.
   - fix a section naming error - ".init.text" rather than ".text.init"
   - preallocate DMA debug memory at core_initcall() time rather than
     fs_initcall(), as we have some core drivers that need to use DMA
     mapping - and that triggers a kernel warning from the DMA debug
     code.
   - fix XIP kernels after the ro_after_init changes made this data
     permanently read-only"
