2008-07-22x86: add PTE_FLAGS_MASKJeremy Fitzhardinge
PTE_PFN_MASK was getting lonely, so I made it a friend. Signed-off-by: Jeremy Fitzhardinge <jeremy@goop.org> Cc: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-07-22x86: rename PTE_MASK to PTE_PFN_MASKJeremy Fitzhardinge
Rusty, in his peevish way, complained that macros defining constants should have a name which somewhat accurately reflects the actual purpose of the constant. Aside from the fact that PTE_MASK gives no clue as to what's actually being masked, and is misleadingly similar to the functionally entirely different PMD_MASK, PUD_MASK and PGD_MASK, I don't really see what the problem is. But if this patch silences the incessent noise, then it will have achieved its goal (TODO: write test-case).

2008-04-17x86: clean up the page table dumper and add 32-bit supportH. Peter Anvin
Clean up the page table dumper (fix boundary conditions, table driven address ranges, some formatting changes since it is no longer using the kernel log but a separate virtual file), and generalize to 32 bits.

2008-04-17x86: add code to dump the (kernel) page tables for visual inspection by ↵Arjan van de Ven
kernel developers This patch adds code to the kernel to have an (optional) /proc/kernel_page_tables debug file that basically dumps the kernel pagetables; this allows us kernel developers to verify that nothing fishy is going on and that the various mappings are set up correctly. This was quite useful in finding various change_page_attr() bugs, and is very likely to be useful in the future as well.
