Merge common code between PowerPC and microblaze. This patch merges the code that scans the tree and registers devices. The functions merged are of_platform_bus_probe(), of_platform_bus_create(), and of_platform_device_create(). This patch also move the of_default_bus_ids[] table out of a Microblaze header file and makes it non-static. The device ids table isn't merged because powerpc and microblaze use different default data.

Microblaze and PowerPC share a large chunk of code for translating OF device tree data into usable addresses. Differences between the two consist of cosmetic differences, and the addition of dma-ranges support code to powerpc but not microblaze. This patch moves the powerpc version into common code and applies many of the cosmetic (non-functional) changes from the microblaze version.

Merge common irq mapping code between PowerPC and Microblaze. This patch merges of_irq_find_parent(), of_irq_map_raw() and of_irq_map_one(). The functions are dependent on one another, so all three are merged in a single patch. Other than cosmetic difference (ie. DBG() vs. pr_debug()), the implementations are identical. of_irq_to_resource() is also merged, but in this case the implementations are different. This patch drops the microblaze version and uses the powerpc implementation unchanged. The microblaze version essentially open-coded irq_of_parse_and_map() which it does not need to do. Therefore the powerpc version is safe to adopt.

Now that the device tree node pointer has been moved out of struct of_device and into the common struct device, there isn't anything unique about of_device anymore. In fact, there isn't much need for a separate of_bus when all busses have access to OF style probing. arch/powerpc and arch/microblaze are moving away from using the of_bus and using the regular platform bus instead for mmio devices. This patch makes of_device the same as platform_device as a stepping stone in migrating of_platform_drivers over to the platform bus.

This patch moves SPARC architecture specific data members out of struct of_device and into the pdev_archdata structure. The reason for this change is to unify the struct of_device definition amongst all the architectures. It also remvoes the .sysdata, .slot, .portid and .clock_freq properties because they aren't actually used by anything. A subsequent patch will replace struct of_device entirely with struct platform_device and the of_platform support code will share common routines with the platform bus (but the bus instances themselves can remain separate). This patch also adds 'struct resources *resource' and num_resources to match the fields defined in struct platform_device. After this change, 'struct platform_device' can be used as a drop-in replacement for 'struct of_platform'. This change is in preparation for merging the of_platform_bus_type with the platform_bus_type. Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Acked-by: NDavid S.

When going to standby mode mpc code maps the whole soc5200 node to access warious MBAR registers. However as of_iomap uses 'reg' property of device node, only small part of MBAR is getting mapped. Thus pm code gets oops when trying to access high parts of MBAR. As a way to overcome this, make mpc52xx_pm_prepare() explicitly map whole MBAR (0xc0000).

Yannick found that video does not work with 2.6.34. The cause of this bug was that the BIOS had assigned the wrong range to the PCI bridge above the video device. Before 2.6.34 the kernel would have shrunk the size of the bridge window, but since d65245c3 PCI: don't shrink bridge resources the kernel will avoid shrinking BIOS ranges. So zero out the old range if we fail to claim it at boot time; this will cause us to allocate a new range at startup, restoring the 2.6.34 behavior. Fixes regression https://bugzilla.kernel.org/show_bug.cgi?id=16009.

Reinstate the null behaviour that the in-kernel gdbstub had for the GDB remote protocol 'p' command (retrieve a single register value) prior to commit 7ca8b9c0 ("frv: extend gdbstub to support more features of gdb"). Before that, the 'p' command just returned an empty reply, which causes gdb to then go and use the 'g' command. However, since that commit, the 'p' command returns an error string, which causes gdb to abort its connection to the target. Not all gdb versions are affected, some use try 'g' first, and if that works, don't bother with 'p', and so don't see the error.

If cr0.wp=0, we have to allow the guest kernel access to a page with pte.w=0. We do that by setting spte.w=1, since the host cr0.wp must remain set so the host can write protect pages. Once we allow write access, we must remove user access otherwise we mistakenly allow the user to write the page.

Always invalidate spte and flush TLBs when changing page size, to make sure different sized translations for the same address are never cached in a CPU's TLB.

When CONFIG_DEBUG_HIGHMEM is used, the fixmap entry used for a highmem page by kmap_atomic() is always cleared by kunmap_atomic(). This helps find bad usages such as dereferences after the unmap, or overflow into the adjacent fixmap areas. But this debugging aid is completely bypassed when a kmap for the same page already exists as the kmap is reused instead. ON VIVT systems we have no choice but to reuse that kmap due to cache coherency issues, but on non VIVT systems we should always force the fixmap usage when debugging is active.
