This patch series fixes an oops when loading the radeon driver on old Macs with a 32-bit EFI implementation. Tested on a MacPro 1,1 with a Radeon X1900 XT card and 32-bit kernel.

This patch series fixes an oops when loading the radeon driver on old Macs with a 32-bit EFI implementation. Tested on a MacPro 1,1 with a Radeon X1900 XT card and 32-bit kernel. Changes in v2: - Add iounmap() call in nouveau - Update function comment for pci_platform_rom() - Minor changes to commit messages Mikel Rychliski (2): drm/radeon: Stop directly referencing iomem PCI: Use

This series removes some no longer needed stuff from paravirt infrastructure and puts large quantities of paravirt ops under a new config option PARAVIRT_XXL which is selected by XEN_PV only. A pvops kernel without XEN_PV being configured is about 2.5% smaller with this series applied. tip commit 5800dc5c19f34e6e03b5adab1282535cb102fafd ("x86/paravirt: Fix spectre-v2 mitigations for

pci_platform_rom() returns an __iomem pointer which should not be accessed directly. Change radeon_read_platform_bios() to use memcpy_fromio() instead of calling kmemdup() on the __iomem pointer.

A large amount of paravirt ops is used by Xen PV guests only. Add a new config option PARAVIRT_XXL which is selected by XEN_PV. Later we can put the Xen PV only paravirt ops under the PARACVIRT_XXL umbrella.

On some EFI systems, the video BIOS is provided by the EFI firmware. The boot stub code stores the physical address of the ROM image in pdev->rom. Currently we attempt to access this pointer using phys_to_virt(), which doesn't work with CONFIG_HIGHMEM. On these systems, attempting to load the radeon module on a x86_32 kernel can result in the following: BUG: unable to handle page

Instead of using six globally visible paravirt ops structures combine them in a single structure, keeping the original structures as sub-structures. This avoids the need to assemble struct paravirt_patch_template at runtime on the stack each time apply_paravirt() is being called (i.e. when loading a module).
