2011-08-03x86: don't include xen/xen.h in <asm/io.h> unless XEN is enabledLinus Torvalds1-2/+1
Dmitry Kasatkin reports: "kernel-devel package with kernel headers have no <include/xen> directory if XEN is disabled. Modules which inclide asm/io.h won't compile. XEN related content is behind the CONFIG_XEN flag in the io.h. And <xen/xen.h> should be also behind CONFIG_XEN flag." So move the include of <xen/xen.h> down into the section that is conditional on CONFIG_XEN.

2011-08-03cpuidle: replace xen access to x86 pm_idle and default_idleLen Brown1-1/+2
When a Xen Dom0 kernel boots on a hypervisor, it gets access to the raw-hardware ACPI tables. While it parses the idle tables for the hypervisor's beneift, it uses HLT for its own idle. Rather than have xen scribble on pm_idle and access default_idle, have it simply disable_cpuidle() so acpi_idle will not load and architecture default HLT will be used. cc: xen-devel@lists.xensource.com Tested-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Acked-by: H.

2011-08-03mrst_pmu: driver for Intel Moorestown Power Management UnitLen Brown3-0/+1052
The Moorestown (MRST) Power Management Unit (PMU) driver directs the SOC power states in the "Langwell" south complex (SCU). It hooks pci_platform_pm_ops[] and thus observes all PCI ".set_state" requests. For devices in the SC, the pmu driver translates those PCI requests into the appropriate commands for the SCU. The PMU driver helps implement S0i3, a deep system idle power idle state. Entry into S0i3 is via cpuidle, just like regular processor c-states. S0i3 depends on pre-conditions including uni-processor, graphics off, and certain IO devices in the SC must be off. If those pre-conditions are met, then the PMU allows cpuidle to enter S0i3, otherwise such requests are demoted, either to Atom C4 or Atom C6. This driver is based on prototype work by Bruce Flemming, Illyas Mansoor, Rajeev D. Muralidhar, Vishwesh M. Rudramuni, Hari Seshadri and Sujith Thomas. The current driver also includes contributions from H. Peter Anvin, Arjan van de Ven, Kristen Accardi, and Yong Wang. Thanks for additional review feedback from Alan Cox and Randy Dunlap.

2011-08-03Add Kconfig option ARCH_HAVE_NMI_SAFE_CMPXCHGHuang Ying13-0/+15
cmpxchg() is widely used by lockless code, including NMI-safe lockless code. But on some architectures, the cmpxchg() implementation is not NMI-safe, on these architectures the lockless code may need a spin_trylock_irqsave() based implementation. This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that NMI-safe lockless code can depend on it or provide different implementation according to it. On many architectures, cmpxchg is only NMI-safe for several specific operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).

2011-07-30m68k/atari: Reserve some ST-RAM early on for device buffer useMichael Schmitz4-298/+70
Based on an original patch from Michael Schmitz: Because mem_init() is now called before device init, devices that rely on ST-RAM may find all ST-RAM already allocated to other users by the time device init happens. In particular, a large initrd RAM disk may use up enough of ST-RAM to cause atari_stram_alloc() to resort to __get_dma_pages() allocation. In the current state of Atari memory management, all of RAM is marked DMA capable, so __get_dma_pages() may well return RAM that is not in actual fact DMA capable. Using this for frame buffer or SCSI DMA buffer causes subtle failure. The ST-RAM allocator has been changed to allocate memory from a pool of reserved ST-RAM of configurable size, set aside on ST-RAM init (i.e. before mem_init()). As long as this pool is not exhausted, allocation of real ST-RAM can be guaranteed. Other changes: - Replace the custom allocator in the ST-RAM pool by the existing allocator in the resource subsystem, - Remove mem_init_done and its hook, as memory init is now done before device init, - Remove /proc/stram, as ST-RAM usage now shows up under /proc/iomem, e.g. 005f2000-006f1fff : ST-RAM Pool 005f2000-0063dfff : atafb 0063e000-00641fff : ataflop 00642000-00642fff : SCSI Signed-off-by: Michael Schmitz <schmitz@debian.org> [Andreas Schwab <schwab@linux-m68k.org>: Use memparse()] [Geert: Use the resource subsystem instead of a custom allocator] Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

The address that's passed to _sparc_find_resource() should always be the start address of a resource: - iounmap() passes a page-aligned virtual address, while the original address was created by adding the in-page offset to the resource's start address, - sbus_free_coherent() and pci32_free_coherent() should be passed an address obtained from sbus_alloc_coherent() resp. pci32_alloc_coherent(), which is always a resource's start address.

2011-07-30m68k/amiga: Chip RAM - Always allocate from the start of memoryGeert Uytterhoeven1-20/+15
As of commit 5df1abdbd37af2ae317a1c5b5944173284dc55d6 ('m68k/amiga: Fix "debug=mem"'), "debug=mem" no longer uses amiga_chip_alloc_res(), so we can remove the hack to prefer memory at the safe end. This allows to simplify the code and make amiga_chip_alloc() just call amiga_chip_alloc_res() internally. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2011-07-30m68k/amiga: Chip RAM - Convert from printk() to pr_*()Geert Uytterhoeven1-20/+8
and fix a few formattings: - resource sizes are now resource_size_t, use %pR to make it future proof, - use %lu for unsigned long. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
