From ffc45571dfb4b70e7eda8d97f64a05f5e5a992ac Mon Sep 17 00:00:00 2001 From: Aron Griffis Date: Tue, 17 Oct 2006 00:28:15 -0400 Subject: [IA64] move ioremap/ioremap_nocache under __KERNEL__ I noticed these are declared extern outside of __KERNEL__, but surely they wouldn't be available to userland since they're defined in ioremap.c. Am I missing something here? If I'm right about this, then there's probably a good deal of other stuff in io.h that could move inside __KERNEL__, but at least this is a start.

Section 11.10.2.1.3, "Making PAL Procedures Calls in Physical or Virtual Mode," of the SDM (rev 2.2), says we must therefore make all PAL calls with PSR.ic = 1 so that Linux can handle any TLB faults. PAL_CALL_IC_OFF is currently unused, and as long as we use the ITR + DTC strategy, we can't use it. So remove it. I also removed the code in ia64_pal_call_static() that conditionally cleared PSR.ic.
