This series renames pmd_mknotpresent() as pmd_mkinvalid(). Before that it drops an existing pmd_mknotpresent() definition from powerpc platform which was never required as it defines it's pmdp_invalidate() through subscribing __HAVE_ARCH_PMDP_INVALIDATE. This does not create any functional change. This rename was suggested by Catalin during a previous discussion while we were trying to change

I'm sure I misunderstand something, but what happens if we use QEMU with TCG instead of KVM, i.e. a big endian powerpc kernel guest on x86_64 little endian host ? Do you forbid the use of

I''m looking for a smooth way to implement paging over a combination of two tables. My application tracks which books and movies you have borrowed from me. For reasons that make sense elsewhere in the application, these are seperated out into two tables: book_borrowers and movie_borrowers and therefore 2 different activerec objects: BookBorrower and MovieBorrower This particular screen

From: Thierry Reding <treding at nvidia.com> The ARM_DMA_USE_IOMMU Kconfig option has side-effects that drivers can not opt into but have to explicitly opt out of. This can lead to subtle bugs that are difficult to track down and not immediately obvious to be related to this Kconfig option. To avoid this confusion, always enable the option to expose any lurking bugs once and allow any
