2009-03-05x86: ifdef 32-bit and 64-bit pfn setup in init_memory_mapping()Pekka Enberg
Impact: cleanup To reduce the diff between the 32-bit and 64-bit versions of init_memory_mapping(), ifdef configuration specific pfn setup code in the function.

2009-03-05x86: add table start and end sanity checks to 32-bit init_memory_mapping()Pekka Enberg
Impact: cleanup This patch adds a sanity check to the 32-bit version of init_memory_mapping() to reduce the diff to the 64-bit version.

2009-03-05x86: unify kernel_physical_mapping_init() call in init_memory_mapping()Pekka Enberg
Impact: cleanup The 64-bit version of init_memory_mapping() uses the last mapped address returned from kernel_physical_mapping_init() whereas the 32-bit version doesn't. This patch adds relevant ifdefs to both versions of the function to reduce the diff between them.

2009-03-05x86: rename after_init_bootmem to after_bootmem in mm/init_32.cPekka Enberg
Impact: cleanup This patch renames after_init_bootmem to after_bootmem in mm/init_32.c to reduce the diff to the 64-bit version of of init_memory_mapping().

2009-03-05x86: remove unnecessary save_mr() sanity checkPekka Enberg
Impact: cleanup The save_mr() function already checks that start_pfn is less than end_pfn so we can remove the unnecessary check which reduces the diff between the 32-bit and the 64-bit versions of init_memory_mapping().

2009-03-05x86: find_early_table_space() unificationPekka Enberg
Impact: cleanup There are some minor differences between the 32-bit and 64-bit find_early_table_space() functions. This patch wraps those differences under CONFIG_X86_32 to make the function identical on both configurations.

2009-03-04x86: set_highmem_pages_init() cleanup, #2Pekka Enberg
Impact: cleanup The zones are set up at this stage so there's a highmem zone available even for the UMA case. The only difference there is that for machines that have CONFIG_HIGHMEM enabled but don't have any highmem available, ->zone_start_pfn is zero whereas highstart_pfn is non-zero). The field is left zeroed because of the !size test in free_area_init_core() but shouldn't be a problem because add_highpages_with_active_regions() handles empty ranges just fine.

2009-03-03x86: set_highmem_pages_init() cleanupPekka Enberg
Impact: cleanup This patch moves set_highmem_pages_init() to arch/x86/mm/highmem_32.c. The declaration of the function is kept in asm/numa_32.h because asm/highmem.h is included only if CONFIG_HIGHMEM is enabled so we can't put the empty static inline function there.

2009-03-02x86 mmiotrace: fix race with release_kmmio_fault_page()Pekka Paalanen
There was a theoretical possibility to a race between arming a page in post_kmmio_handler() and disarming the page in release_kmmio_fault_page(): cpu0 cpu1 ------------------------------------------------------------------ mmiotrace shutdown enter release_kmmio_fault_page fault on the page disarm the page disarm the page handle the MMIO access re-arm the page put the page on release list remove_kmmio_fault_pages() fault on the page page not known to mmiotrace fall back to do_page_fault() *KABOOM* (This scenario also shows the double disarm case which is allowed.)

io_mapping_create_wc should take a resource_size_t parameter in place of unsigned long. With unsigned long, there will be no way to map greater than 4GB address in i386/32 bit. On x86, greater than 4GB addresses cannot be mapped on i386 without PAE. Return error for such a case.
