The address limit is already set in flush_old_exec() so those calls to set_fs(USER_DS) are redundant. Signed-off-by:

Heiko Carstens authored
While implementing cmpxchg_double() on s390 I realized that we don't set CONFIG_CMPXCHG_LOCAL despite the fact that we have support for it. However setting that option will increase the size of struct page by eight bytes on 64 bit, which we certainly do not want. Also, it doesn't make sense that a present cpu feature should increase the size of struct page. Besides that it looks like the dependency to CMPXCHG_LOCAL is wrong and that it should depend on CMPXCHG_DOUBLE instead. This patch: If an architecture supports CMPXCHG_LOCAL this shouldn't result automatically in larger struct pages if the SLUB allocator is used. Instead introduce a new config option "HAVE_ALIGNED_STRUCT_PAGE" which can be selected if a double word aligned struct page is required. Also update x86 Kconfig so that it should work as before.

The RSK+ setup code was doing some pretty dubious things with parse_mtd_partitions() in order to populate the physmap-flash map platform data. The physmap-flash driver contains all of the functionality that we require already, so simply drop the special casing and pad out the platform data accordingly. Signed-off-by: -

The cache functions lock out interrupts for long periods; this patch reduces the impact when operating on large address ranges. In such cases it will: - Invalidate the entire cache rather than individual addresses. - Do nothing when flushing the operand cache in write-through mode. - When flushing the operand cache in write-back mdoe, index the search for matching addresses on the cache entires instead of the addresses to flush Note: sh2a__flush_purge_region was only invalidating the operand cache, this adds flush.
