x86/boot: Disable the address-of-packed-member compiler warning
The clang warning 'address-of-packed-member' is disabled for the general
kernel code, also disable it for the x86 boot code.
This suppresses a bunch of warnings like this when building with clang:
./arch/x86/include/asm/processor.h:535:30: warning: taking address of
packed member 'sp0' of class or structure 'x86_hw_tss' may result in an
unaligned pointer value [-Waddress-of-packed-member]
return this_cpu_read_stable(cpu_tss.x86_tss.sp0);
^~~~~~~~~~~~~~~~~~~
./arch/x86/include/asm/percpu.h:391:59: note: expanded from macro
'this_cpu_read_stable'
#define this_cpu_read_stable(var) percpu_stable_op("mov", var)
^~~
./arch/x86/include/asm/percpu.h:228:16: note: expanded from macro
'percpu_stable_op'
: "p" (&(var)));
