[ Upstream commit a4947e84f23474803b62a2759b5808147e4e15f9 ]
The various array_size functions use SIZE_MAX define, but missed limits.h causes to failure to compile code that needs overflow.h.
In file included from drivers/infiniband/core/uverbs_std_types_device.c:6: ./include/linux/overflow.h: In function 'array_size': ./include/linux/overflow.h:258:10: error: 'SIZE_MAX' undeclared (first use in this function) 258 | return SIZE_MAX; | ^~~~~~~~
