2006-03-29[PATCH] libata: Simplex and other mode filtering logicAlan Cox
Add a field to the host_set called 'flags' (was host_set_flags changed to suit Jeff) Add a simplex_claimed field so we can remember who owns the DMA channel Add a ->mode_filter() hook to allow drivers to filter modes Add docs for mode_filter and set_mode Filter according to simplex state Filter cable in core This provides the needed framework to support all the mode rules found in the PATA world. The simplex filter deals with 'to spec' simplex DMA systems found in older chips. The cable filter avoids duplicating the same rules in each chip driver with PATA. Finally the mode filter is neccessary because drive/chip combinations have errata that forbid certain modes with some drives or types of ATA object. Drive speed setup remains per channel for now and the filters now use the framework Tejun put into place which cleans them up a lot from the older libata-pata patches.

2006-03-28[PATCH] powerpc: Kill _machine and hard-coded platform numbersBenjamin Herrenschmidt
This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine.

2006-03-26[PATCH] Add flush_kernel_dcache_page() APIJames Bottomley
We have a problem in a lot of emulated storage in that it takes a page from get_user_pages() and does something like kmap_atomic(page) modify page kunmap_atomic(page) However, nothing has flushed the kernel cache view of the page before the kunmap. We need a lightweight API to do this, so this new API would specifically be for flushing the kernel cache view of a user page which the kernel has modified. The driver would need to add flush_kernel_dcache_page(page) before the final kunmap.

2006-03-26[PATCH] Add API for flushing Anon pagesJames Bottomley
Currently, get_user_pages() returns fully coherent pages to the kernel for anything other than anonymous pages. This is a problem for things like fuse and the SCSI generic ioctl SG_IO which can potentially wish to do DMA to anonymous pages passed in by users. The fix is to add a new memory management API: flush_anon_page() which is used in get_user_pages() to make anonymous pages coherent.

In other words, if the desktop user is uid=1000 and the mount option uid=1000 is given ( which is done on ubuntu automatically and probably other distributions that use hal ), then if any other user besides uid 1000 owns a file then a 0 will be written to the media as the owning uid instead.

2006-03-25[PATCH] Validate and sanitze itimer timeval from userspaceThomas Gleixner
According to the specification the timevals must be validated and an errorcode -EINVAL returned in case the timevals are not in canonical form. This check was never done in Linux. The pre 2.6.16 code converted invalid timevals silently. Negative timeouts were converted by the timeval_to_jiffies conversion to the maximum timeout. hrtimers and the ktime_t operations expect timevals in canonical form. Otherwise random results might happen on 32 bits machines due to the optimized ktime_add/sub operations. Negative timeouts are treated as already expired. This might break applications which work on pre 2.6.16. To prevent random behaviour and API breakage the timevals are checked and invalid timevals sanitized in a simliar way as the pre 2.6.16 code did. Invalid timevals are reported with a per boot limited number of kernel messages so applications which use this misfeature can be corrected. After a grace period of one year the sanitizing should be replaced by a correct validation check. This is also documented in Documentation/feature-removal-schedule.txt The validation and sanitizing is done inside do_setitimer so all callers (sys_setitimer, compat_sys_setitimer, osf_setitimer) are catched.

2006-03-24[PATCH] cpuset memory spread basic implementationPaul Jackson
This patch provides the implementation and cpuset interface for an alternative memory allocation policy that can be applied to certain kinds of memory allocations, such as the page cache (file system buffers) and some slab caches (such as inode caches). The policy is called "memory spreading." If enabled, it spreads out these kinds of memory allocations over all the nodes allowed to a task, instead of preferring to place them on the node where the task is executing. All other kinds of allocations, including anonymous pages for a tasks stack and data regions, are not affected by this policy choice, and continue to be allocated preferring the node local to execution, as modified by the NUMA mempolicy. There are two boolean flag files per cpuset that control where the kernel allocates pages for the file system buffers and related in kernel data structures. They are called 'memory_spread_page' and 'memory_spread_slab'. If the per-cpuset boolean flag file 'memory_spread_page' is set, then the kernel will spread the file system buffers (page cache) evenly over all the nodes that the faulting task is allowed to use, instead of preferring to put those pages on the node where the task is running. If the per-cpuset boolean flag file 'memory_spread_slab' is set, then the kernel will spread some file system related slab caches, such as for inodes and dentries evenly over all the nodes that the faulting task is allowed to use, instead of preferring to put those pages on the node where the task is running. The implementation is simple. Setting the cpuset flags 'memory_spread_page' or 'memory_spread_cache' turns on the per-process flags PF_SPREAD_PAGE or PF_SPREAD_SLAB, respectively, for each task that is in the cpuset or subsequently joins that cpuset. In subsequent patches, the page allocation calls for the affected page cache and slab caches are modified to perform an inline check for these flags, and if set, a call to a new routine cpuset_mem_spread_node() returns the node to prefer for the allocation. The cpuset_mem_spread_node() routine is also simple. It uses the value of a per-task rotor cpuset_mem_spread_rotor to select the next node in the current tasks mems_allowed to prefer for the allocation. This policy can provide substantial improvements for jobs that need to place thread local data on the corresponding node, but that need to access large file system data sets that need to be spread across the several nodes in the jobs cpuset in order to fit. Without this patch, especially for jobs that might have one thread reading in the data set, the memory allocation across the nodes in the jobs cpuset can become very uneven. A couple of Copyright year ranges are updated as well. And a couple of email addresses that can be found in the MAINTAINERS file are removed.
