From: Arnd Bergmann <a...@arndb.de>
Randconfig builds on 32-bit machines show lots of warnings for
the i915 driver for passing a 32-bit value into __const_hweight64():
drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c:2584:9: error: shift count >=
width of type [-Werror,-Wshift-count-overflow]
return hweight64(VDBOX_MASK(&i915->gt));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
include/asm-generic/bitops/const_hweight.h:29:49: note: expanded from macro
'hweight64'
#define hweight64(w) (__builtin_constant_p(w) ? __const_hweight64(w) :
__arch_hweight64(w))
Change it to hweight_long() to avoid the warning.
