Merge absolute_pointer macro series from Guenter Roeck:
"Kernel test builds currently fail for several architectures with error
messages such as the following.
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 if gcc's builtin functions are used for
those operations.
This series introduces absolute_pointer() to fix the problem.
absolute_pointer() disassociates a pointer from its originating symbol
type and context, and thus prevents gcc from making assumptions about
pointers passed to memory operations"
* emailed patches from Guenter Roeck <linux@roeck-us.net>:
alpha: Use absolute_pointer to define COMMAND_LINE
alpha: Move setup.h out of uapi
net: i825xx: Use absolute_pointer for memcpy from fixed memory location
compiler.h: Introduce absolute_pointer macro
