x86: unify free_init_pages() and free_initmem() Impact: unification This patch introduces a common arch/x86/mm/init.c and moves the identical free_init_pages() and free_initmem() functions to the file.

x86: unify arch/x86/mm/Makefile Unify arch/x86/mm/Makefile between 32 and 64 bits. All configuration variables that are protected by Kconfig constraints have been put in the common part of the Makefile; however, the NUMA files are totally different between 32 and 64 bits and are handled via an ifdef.

xen: make -fstack-protector work under Xen -fstack-protector uses a special per-cpu "stack canary" value. gcc generates special code in each function to test the canary to make sure that the function's stack hasn't been overrun. On x86-64, this is simply an offset of %gs, which is the usual per-cpu base segment register, so setting it up simply requires loading %gs's base as normal. On i386, the stack protector segment is %gs (rather than the usual kernel percpu %fs segment register). This requires setting up the full kernel GDT and then loading %gs accordingly. We also need to make sure %gs is initialized when bringing up secondary cpus too. To keep things consistent, we do the full GDT/segment register setup on both architectures. Because we need to avoid -fstack-protected code before setting up the GDT and because there's no way to disable it on a per-function basis, several files need to have stack-protector inhibited.

x86: split __phys_addr out into separate file Split __phys_addr out into its own file so we can disable -fstack-protector in a fine-grained fashion. Also it doesn't have terribly much to do with the rest of ioremap.c. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

x86: replace CONFIG_X86_SMP with CONFIG_SMP The x86/Voyager subarch used to have this distinction between 'x86 SMP support' and 'Voyager SMP support': config X86_SMP bool depends on SMP && ((X86_32 && !X86_VOYAGER) || X86_64) This is a pointless distinction - Voyager can (and already does) use smp_ops to implement various SMP quirks it has - and it can be extended more to cover all the specialities of Voyager. So remove this complication in the Kconfig space. Signed-off-by: Ingo Molnar <mingo@elte.hu>

x86: add iomap_atomic*()/iounmap_atomic() on 32-bit using fixmaps Impact: introduce new APIs, separate kmap code from CONFIG_HIGHMEM This takes the code used for CONFIG_HIGHMEM memory mappings except that it's designed for dynamic IO resource mapping.

kmemcheck: add the kmemcheck core General description: kmemcheck is a patch to the linux kernel that detects use of uninitialized memory. It does this by trapping every read and write to memory that was allocated dynamically (e.g. using kmalloc()). If a memory address is read that has not previously been written to, a message is printed to the kernel log. Thanks to Andi Kleen for the set_memory_4k() solution. Andrew Morton suggested documenting the shadow member of struct page.
