[ARM] 3750/3: Fix double VFP emulation for EABI kernels
Patch from Daniel Jacobowitz vfp_put_double didn't work in a CONFIG_AEABI kernel. By swapping the arguments, we arrange for them to be in the same place regardless of ABI. I made the same change to vfp_put_float for consistency. Signed-off-by: Daniel Jacobowitz <dan@codesourcery.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
