The PAT MSR contains 8 entries each specifying one of 6 possible cache modes. A pte references one of those entries via 3 bits: _PAGE_PAT, _PAGE_PWT and _PAGE_PCD. The Linux kernel currently supports only 4 different cache modes. The PAT MSR is set up in a way that the setting of _PAGE_PAT in a pte doesn't matter: the top 4 entries in the PAT MSR are the same as the 4 lower entries. This results in the kernel not supporting e.g. write-through mode. Especially this cache mode would speed up drivers of video cards which now have to use uncached accesses. OTOH some old processors (Pentium) don't support PAT correctly and the Xen hypervisor has been using a different PAT MSR configuration for some time now and can't change that as this setting is part of the ABI. This patch set abstracts the cache mode from the pte and introduces tables to translate between cache mode and pte bits (the default cache mode "write back" is hard-wired to PAT entry 0). The tables are statically initialized with values being compatible to old processors and current usage. As soon as the PAT MSR is changed (or - in case of Xen - is read at boot time) the tables are changed accordingly. Requests of mappings with special cache modes are always possible now, in case they are not supported there will be a fallback to a compatible but slower mode. Summing it up, this patch set adds the following features: - capability to support WT and WP cache modes on processors with full PAT support - processors with no or uncorrect PAT support are still working as today, even if WT or WP cache mode are selected by drivers for some pages - reduction of Xen special handling regarding cache mode Another change is a boot speedup on ridiculously large RAM systems, plus other smaller fixes" * 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (22 commits) x86: mm: Move PAT only functions to mm/pat.c xen: Support Xen pv-domains using PAT x86: Enable PAT to use cache mode translation tables x86: Respect PAT bit when copying pte values between large and normal pages x86: Support PAT bit in pagetable dump for lower levels x86: Clean up pgtable_types.h x86: Use new cache mode type in memtype related functions x86: Use new cache mode type in mm/ioremap.c x86: Use new cache mode type in setting page attributes x86: Remove looking for setting of _PAGE_PAT_LARGE in pageattr.c x86: Use new cache mode type in track_pfn_remap() and track_pfn_insert() x86: Use new cache mode type in mm/iomap_32.c x86: Use new cache mode type in asm/pgtable.h x86: Use new cache mode type in arch/x86/mm/init_64.c x86: Use new cache mode type in arch/x86/pci x86: Use new cache mode type in drivers/video/fbdev/vermilion x86: Use new cache mode type in drivers/video/fbdev/gbefb.c x86: Use new cache mode type in include/asm/fb.h x86: Make page cache mode a real type x86: mm: Use 2GB memory block size on large-memory x86-64 systems ...

All remaining board files that were written in C are dropped, and the ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed altogether. Cleaning up the last pieces was great fun, so I took the time to do some of the coding myself and removed several hundred code lines that ended up unused after the board files were done. There are still a couple of AT91 specific device drivers that are not converted to DT (CF, USB-OTG) and currently not working, and the platform itself is not "multiplatform"-enabled, but both issues are going to be taken care of in the 3.20 cycle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PLL settings are committed by setting GO bit, which is then cleared by the HW when the settings have been taken into use. The current PLL code handles this wrong: instead of waiting for the bit to be cleared, it waits for the bit to be set. Usually, the bit is always set, as the CPU has just set it before. However, if the CPU takes enough time between setting the GO bit and checking it, the HW may already have cleared the bit and this leads to timeout error. Fix the wait to check the bit properly.

During resume, after powering up the PM domain, interrupts are re-enabled, and an interrupt storm happens due to incorrect interrupt polarity settings: irq 163: nobody cared (try booting with the "irqpoll" option) ... Disabling IRQ #163 To fix this, re-initialize the interrupt polarity settings, and the htop1 register block (if present), during resume. As the .suspend_noirq() and .resume_noirq() callbacks are not called when using the generic PM domain, the normal .resume() callback is used, and the device interrupt needs to be disabled/enabled manually. This fixes resume from s2ram with power down of the A4MP PM domain on r8a7740/Armadillo.

The bug happens under these conditions: * the end of the destination area of a copy operation is aligned on a long word boundary * the end of the source area is not aligned on a long word boundary * we are copying more than one long word In this case, the variable shift is non-zero and the variable first is zero. The statements FB_WRITEL(comp(d0, FB_READL(dst), first), dst) reads the last long word of the destination and writes it back unchanged (because first is zero). Correctly, we should write the variable d0 to the last word of the destination in this case. This patch fixes the bug by introducing and extra test if first is zero. The patch also removes the references to fb_memmove in the code that is commented out because fb_memmove was removed from framebuffer subsystem.
