net: checksum: drop the linux/uaccess.h include
net/checksum.h pulls in linux/uaccess.h which is large. In the x86 header the include seems to not be needed at all. ARM on the other hand does not include uaccess.h, even tho it calls access_ok(). In the generic implementation guard the include of linux/uaccess.h with the same condition as the code that needs it. With this change pre-processed net/checksum.h shrinks on x86 from 30616 lines to just 1193. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
