2019-08-16	ia64: remove now unused machvec indirections	Christoph Hellwig	1	-10/+2
	With the SGI SN2 machvec removal most of the indirections are unused now, so remove them. This includes the entire removal of the mmio read/write macros as the generic ones are identical to the asm-generic/io.h version.

2019-04-08	ia64/mmiowb: Add unconditional mmiowb() to arch_spin_unlock()	Will Deacon	1	-0/+25
	The mmiowb() macro is horribly difficult to use and drivers will continue to work most of the time if they omit a call when it is required. Rather than rely on driver authors getting this right, push mmiowb() into arch_spin_unlock() for ia64. If this is deemed to be a performance issue, a subsequent optimisation could make use of ARCH_HAS_MMIOWB to elide the barrier in cases where no I/O writes were performed inside the critical section.
