Rather than hacking up the headers some more, remove asm/pgtable.h, since early_printk.c doesn't actually need it. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

2008-12-12x86: remove simnow earlyprintk supportAndi Kleen
Impact: remove obsolete code The later versions of SimNow! actually all have serial console emulation, so the direct interface isn't needed anymore. So remove the undocumented simnow earlyprintk console. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2008-06-18x86, generic: mark early_printk as asmlinkageJiri Slaby
It's not explicitly marked as asmlinkage, but invoked from x86_32 startup code with parameters on stack. No other architectures define early_printk and none of them are affected by this change, since defines asmlinkage as empty token. Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Cc: H.
