[MIPS] Fixup copy_from_user_inatomic From the 01408c4939479ec46c15aa7ef6e2406be50eeeca log message: The problem is that when we write to a file, the copy from userspace to pagecache is first done with preemption disabled, so if the source address is not immediately available the copy fails and zeros the destination. This is a problem because a concurrent read (which admittedly is an odd thing to do) might see zeros rather that was there before the write, or what was there after, or some mixture of the two (any of these being a reasonable thing to see). If the copy did fail, it will immediately be retried with preemption re-enabled so any transient problem with accessing the source won't cause an error. The first copying does not need to zero any uncopied bytes, and doing so causes the problem. It uses copy_from_user_atomic rather than copy_from_user so the simple expedient is to change copy_from_user_atomic to not zero out bytes on failure. < --- end cite --- > This patch finally implements at least a not so pretty solution by duplicating the relevant part of __copy_user.

[MIPS] Unify csum_partial.S The 32-bit version and 64-bit version are almost equal. Unify them. This makes further improvements (for example, copying with parallel, supporting PREFETCH, etc.) easier.

[MIPS] Iomap implementation. This implementation has support for the concept of one separate ioport address space by PCI domain. A pointer to the virtual address where the port space of a domain has been mapped has been added to struct pci_controller and systems should be fixed to fill in this value. For single domain systems this will be the same value as passed to set_io_port_base(). Signed-off-by: Ralf Baechle <ralf@linux-mips.org> 2006-12-07 22:35:43 +08:00			`obj-y += iomap.o`

[MIPS] Fix optimization for size build. It took a while longer than on other architectures but gcc has finally started to strike us as well ...
