[Xen-devel] [PATCH] arm: cast int<->pointer via uintptr_t

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

Fixes build on arm64:

gic.c: In function âgic_irq_eoiâ:
        gic.c:726:16: error: cast from pointer to integer of different size 
[-Werror=pointer-to-int-cast]
        gic.c: In function âmaintenance_interruptâ:
        gic.c:776:29: error: cast to pointer from integer of different size 
[-Werror=int-to-pointer-cast]
        gic.c:778:64: error: cast to pointer from integer of different size 
[-Werror=int-to-pointer-cast]
        cc1: all warnings being treated as errors
        make[3]: *** [gic.o] Error 1

I forgot to CC the list when I sent this to Stefano & Keir. Given that they
have acked already I intend to apply immediately.
