compiler.h: Introduce absolute_pointer macro
[ Upstream commit f6b5f1a56987de837f8e25cd560847106b8632a8 ]
absolute_pointer() disassociates a pointer from its originating symbol
type and context. Use it to prevent compiler warnings/errors such as
drivers/net/ethernet/i825xx/82596.c: In function 'i82596_probe':
arch/m68k/include/asm/string.h:72:25: error:
'__builtin_memcpy' reading 6 bytes from a region of size 0 [-Werror=stringop-overread]
Such warnings may be reported by gcc 11.x for string and memory
operations on fixed addresses.
