clocksource: Mmio: remove artificial 32bit limitation The EP93xx is registering a clocksource of 40 bits with clocksource_mmio_init() but this is not working because of this artificial limitation. It works fine to lift the uppe limit to 64 bits, and since cycle_t is u64, it should intuitively have been like that from the beginning.

clocksource: add common mmio clocksource Add a generic mmio clocksource, covering both 32-bit and 16-bit register access sizes, for up or down counters. This can be used to easily create clocksources for simple counter-based implementations.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

clocksource/drivers/mmio: Make the code compatible with modules The next changes will bring the module support on the timer drivers. Those use the API exported by the mmio clocksource which are not exporting their symbols. Fix that by adding EXPORT_SYMBOL_GPL().
