2014-07-23	acpi, apei, ghes: Factor out ioremap virtual memory for IRQ and NMI context.	Tomasz Nowicki	1	-0/+6
	GHES currently maps two pages with atomic_ioremap. From now on, NMI is architectural depended so there is no need to allocate an NMI page for platforms without NMI support. To make it possible to not use a second page, swap the existing page order so that the IRQ context page is first, and the optional NMI context page is second. Then, use HAVE_ACPI_APEI_NMI to decide how many pages are to be allocated.

2014-07-23	apei, mce: Factor out APEI architecture specific MCE calls.	Tomasz Nowicki	1	-0/+56
	This commit abstracts MCE calls and provides weak corresponding default implementation for those architectures which do not need arch specific actions. Each platform willing to do additional architectural actions should provides desired function definition. It allows us to avoid wrap code into #ifdef in generic code and prevent new platform from introducing dummy stub function too. Initially, there are two APEI arch-specific calls: - arch_apei_enable_cmcff() - arch_apei_report_mem_error() Both interact with MCE driver for X86 architecture.
