| 2020-10-02 | RISC-V: Add page table dump support for uefi | Atish Patra | 1 | -6/+42 | |
| Extend the current page table dump support in RISC-V to include efi pages as well. Here is the output of efi runtime page table mappings. ---[ UEFI runtime start ]--- 0x0000000020002000-0x0000000020003000 0x00000000be732000 4K PTE D A . . .

| 2020-06-09 | mm: introduce include/linux/pgtable.h | Mike Rapoport | 1 | -1/+1 | |
| The include/linux/pgtable.h is going to be the home of generic page table manipulation functions. Start with moving asm-generic/pgtable.h to include/linux/pgtable.h and make the latter include asm/pgtable.h.

| 2020-06-02 | mm: ptdump: expand type of 'val' in note_page() | Steven Price | 1 | -1/+1 | |
| The page table entry is passed in the 'val' argument to note_page(), however this was previously an "unsigned long" which is fine on 64-bit platforms. But for 32 bit x86 it is not always big enough to contain a page table entry which may be 64 bits. Change the type to u64 to ensure that it is always big enough.

| 2020-03-26 | riscv: Add support to dump the kernel page tables | Zong Li | 1 | -0/+317 | |
| In a similar manner to arm64, x86, powerpc, etc., it can traverse all page tables, and dump the page table layout with the memory types and permissions. Add a debugfs file at /sys/kernel/debug/kernel_page_tables to export the page table layout to userspace.
