linkage: add generic GLOBAL() macro
Declaring a global symbol in assembly is tedious, error-prone, and painful to read. While ENTRY() exists, this is supposed to be used for function entry points, and this affects alignment in a potentially undesireable manner. Instead, let's add a generic GLOBAL() macro for this, as x86 added locally in commit: 95695547 ("x86: asm linkage - introduce GLOBAL macro") ... thus allowing us to use this more freely in the kernel.
