Kill L1_CACHE_SHIFT from all arches. Since L1_CACHE_SHIFT_MAX is not used anymore with the introduction of INTERNODE_CACHE, kill L1_CACHE_SHIFT_MAX. Signed-off-by:

____cacheline_maxaligned_in_smp is currently used to align critical structures and avoid false sharing. It uses per-arch L1_CACHE_SHIFT_MAX and people find L1_CACHE_SHIFT_MAX useless. However, we have been using ____cacheline_maxaligned_in_smp to align structures on the internode cacheline size. As per Andi's suggestion, following patch kills ____cacheline_maxaligned_in_smp and introduces INTERNODE_CACHE_SHIFT, which defaults to L1_CACHE_SHIFT for all arches. Arches needing L3/Internode cacheline alignment can define INTERNODE_CACHE_SHIFT in the arch asm/cache.h. Patch replaces ____cacheline_maxaligned_in_smp with ____cacheline_internodealigned_in_smp With this patch, L1_CACHE_SHIFT_MAX can be killed Signed-off-by:

David Howells authored
Fix a number of miscellanous items: (1) Declare lock sections in the linker script. (2) Recurse in the correct manner in the arch makefile. (3) asm/bug.h requires asm/linkage.h to be included first. One C file puts asm/bug.h first. (4) Add an empty RTC header file to avoid missing header file errors. (5) sg_dma_address() should use the dma_address member of a scatter list. (6) Add trivial pci_unmap support. (7) Add pgprot_noncached() (8) Discard u_quad_t. (9) Use ~0UL rather than ULONG_MAX in unistd.h in case the latter isn't declared. (10) Add an empty VGA header file to avoid missing header file errors. (11) Add an XOR header file to use the generic XOR stuff. Signed-off-by: -

Force the 8230 serial driver to be built in if the on-CPU UARTs are to be used. It can't be used as a module because the arch setup needs to call into it. Signed-off-by:

Supply various I/O access primitives that are missing for the FRV arch: (*) mmiowb() (*) read*_relaxed() (*) ioport_*map() (*) ioread*(), iowrite*(), ioread*_rep() and iowrite*_rep() (*) pci_io*map() (*) check_signature() The patch also makes __is_PCI_addr() more efficient. Signed-off-by:

Export a number of features required to build all the modules. It also implements the following simple features: (*) csum_partial_copy_from_user() for MMU as well as no-MMU. (*) __ucmpdi2(). so that they can be exported too. Signed-off-by:

David Howells authored
Drop support for debugging features that aren't supported on FRV: (*) EARLY_PRINTK The on-chip UARTs are set up early enough that this isn't required, and VGA support isn't available. There's also a gdbstub available. (*) DEBUG_PAGEALLOC This can't be easily be done since we use huge static mappings to cover the kernel, not pages. Signed-off-by:

PNX010X support for CS89x0 should be conditional on NET_PCI, as it is an 'on board controller' and NET_PCI includes that category of NICs. Since ARCH_PNX0105 was recently changed to ARCH_PNX010X, incorporate that change as well while we're at it. Signed-off-by:

readword() and writeword() take a 'struct net_device *' and deref its ->base_addr member. Make them take the base_addr directly instead, so that we can switch the other occurences of inw/outw in the file over to readword/writeword as well. Signed-off-by:

First discussed at http://marc.theaimsgroup.com/?t=113149255100001&r=1&w=2 - Use the check_range() in mempolicy.c to gather statistics. - Improve the numa_maps code in general and fix some comments. Signed-off-by:

This was was first posted at http://marc.theaimsgroup.com/?l=linux-mm&m=113149240227584&w=2 (Part of this functionality is also contained in the direct migration pathset. The functionality here is more generic and independent of that patchset.) - Add internal flags MPOL_MF_INVERT to control check_range() behavior. - Replace the pagelist passed through by check_range by a general private pointer that may be used for other purposes. (The following patches will use that to merge numa_maps into mempolicy.c and to better group the page migration code in the policy layer) - Improve some comments. Signed-off-by:

Add a boolean "memory_migrate" to each cpuset, represented by a file containing "0" or "1" in each directory below /dev/cpuset. It defaults to false (file contains "0"). It can be set true by writing "1" to the file. If true, then anytime that a task is attached to the cpuset so marked, the pages of that task will be moved to that cpuset, preserving, to the extent practical, the cpuset-relative placement of the pages. Also anytime that a cpuset so marked has its memory placement changed (by writing to its "mems" file), the tasks in that cpuset will have their pages moved to the cpusets new nodes, preserving, to the extent practical, the cpuset-relative placement of the moved pages.
