/dev/mem mmap code was doing memtype reserve/free for a while now. Recently we added memtype tracking in remap_pfn_range, and /dev/mem mmap uses it indirectly. So, we don't need seperate tracking in /dev/mem code any more. That means another ~100 lines of code removed :-).

Fix pat_x_mtrr_type() to use UC_MINUS when the mtrr type return UC. This is to be consistent with ioremap() and ioremap_nocache() which uses UC_MINUS. Consolidate the code such that reserve_memtype() also uses pat_x_mtrr_type() when the caller doesn't specify any special attribute (non WB attribute).

As per SDM, there should not be any aliasing of a WC with any cacheable type across CPUs. That is if one CPU is changing the identity map memtype to _WC, no other CPU at the time of this change should not have a TLB for this page that carries a WB attribute. SDM suggests to make the page not present. But for that we will have to handle any page faults that can potentially happen due to these pages being not present. Other way to deal with this without having any WB mapping is to change the page first to UC and then to WC. This ensures that we meet the SDM requirement of no cacheable alais to WC page. This also has same or lower overhead than marking the page not present and making it present later.

Handle faults and do proper cleanups in set_memory_*() functions. In some cases, these functions were not doing proper free on failure paths. With the changes to tracking memtype of RAM pages in struct page instead of pat list, we do not need the changes in commits c5e147. This patch reverts that change.

Change the identity mapping with the requested attribute first, before we setup the virtual memory mapping with the new requested attribute. This makes sure that there is no window when identity map'ed attribute may disagree with ioremap range on the attribute type. This also avoids doing cpa on the ioremap'ed address twice (first in ioremap_page_range and then in ioremap_change_attr using vaddr), and should improve ioremap performance a bit.

To simplify level irq migration in the presence of interrupt-remapping, Suresh used a virtual vector (io-apic pin number) to eliminate io-apic RTE modification. Level triggered interrupt will appear as an edge to the local apic cpu but still as level to the IO-APIC. So in addition to do the local apic EOI, it still needs to do IO-APIC directed EOI to clear the remote IRR bit in the IO-APIC RTE. Pls refer to Suresh's patch for more details (commit 0280f7c4). Now interrupt remapping is decoupled from x2apic, it also needs to do the directed EOI for apic. Otherwise, apic interrupts won't work correctly.

Impact: Fixes these modes on at least one system The rewrite of the setup code into C resequenced the font setting and register reprogramming phases of configuring nonstandard VGA modes which use 480 scan lines in text mode. However, there exists at least one board (Micro-Star MS-7383 version 2.0) on which this resequencing causes an unusable display. Revert to the original sequencing: set up 480-line mode, install the font, and then adjust the vertical end register appropriately. This failure was masked by the fact that the 480-line setup was broken until checkin 5f641356 (therefore this is not a -stable candidate bug fix.)

The code that enables branch tracing for all (non-constant) branches plays games with the preprocessor and #define's the C 'if ()' construct to do tracing. That's all fine, but it fails for some unusual but valid C code that is sometimes used in macros, notably by the intel-iommu code: if (i=drhd->iommu, drhd->ignored) .. because now the preprocessor complains about multiple arguments to the 'if' macro. So make the macro expansion of this particularly horrid trick use varargs, and handle the case of comma-expressions in if-statements. Use another macro to do it cleanly in just one place. This replaces a patch by David (and acked by Steven) that did this all inside that one already-too-horrid macro.
