| * | memory-hotplug: remove memmap of sparse-vmemmapTang Chen2013-02-241-0/+4

Since pagetable implements are different, each architecture has to provide its own version of vmemmap_free(), just like vmemmap_populate(). Note: vmemmap_free() is not implemented for ia64, ppc, s390, and sparc.

| * | memory-hotplug: implement register_page_bootmem_info_section of sparse-vmemmapYasuaki Ishimatsu2013-02-241-0/+1

So the patch searches pages of virtual mapping and registers the pages by get_page_bootmem(). NOTE: register_page_bootmem_memmap() is not implemented for ia64, ppc, s390, and sparc. So introduce CONFIG_HAVE_BOOTMEM_INFO_NODE and revert register_page_bootmem_info_node() when platform doesn't support it. It's implemented by adding a new Kconfig option named CONFIG_HAVE_BOOTMEM_INFO_NODE, which will be automatically selected by memory-hotplug feature fully supported archs(currently only on x86_64). Since we have 2 config options called MEMORY_HOTPLUG and MEMORY_HOTREMOVE used for memory hot-add and hot-remove separately, and codes in function register_page_bootmem_info_node() are only used for collecting infomation for hot-remove, so reside it under MEMORY_HOTREMOVE. Besides page_isolation.c selected by MEMORY_ISOLATION under MEMORY_HOTPLUG is also such case, move it too.

This change adds a gpio-leds stanza to the lite5200 device tree so that the correct driver can get hooked up. Also, make use of the dtc labels feature to reduce the number of source lines required to add the gpio-controller property to the general purpose timer nodes. In addition, the required #gpio-cells properties are added to the common mpc5200b dtsi include file so that each board doesn't need to add them explicitly. This still doesn't enable gpio mode, 'gpio-controller' is required for that, but it means less work needs to be done by board ports.

Currently this information is not stored during fsl pci controller initialization. This information is required while dealing with iommu groups for pci devices connected to the fsl pci controller. For the case where the pci devices can't be paritioned, they would fall under the same device group as the pci controller. This patch stores the platform device information in the pci controller structure during initialization.

This fixes some issues and improves consistency among the SOCs. Specifically: 1) The P1022 has a v1 PCIe controller, so the compatible property should just say "fsl,mpc8548-pcie". U-Boot does not look for "fsl,p1022-pcie", so it wasn't fixing up the node. 2) The P4080 has a v2.1 PCIe controller, so add that version-specific string to the device tree. Update the kernel to also look for that string. Currently, the kernel looks for "fsl,p4080-pcie" specifically, but eventually that check should be deleted. 3) The P1010 device tree claims compatibility with v2.2 and v2.3, but that's redundant. No other device tree does this. Remove the v2.2 string. 4) The kernel looks for both "fsl,p1023-pcie" and "fsl,qoriq-pcie-v2.2", even though the P1023 device trees has always included both strings. Remove the search for "fsl,p1023-pcie". Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
