For most of the builds we have in GVS userspace is 64 bits. But it seems like at least some L4T userspace builds are either not 32 bits or have an UL that only covers 32 bits. This is seen in GVS: /dvs/git/dirty/git-master_modular/kernel/nvgpu/drivers/gpu/nvgpu/gv11b/mm_gv11b.c: In function 'gv11b_gpu_phys_addr': /dvs/git/dirty/git-master_modular/kernel/nvgpu/drivers/gpu/nvgpu/gv11b/mm_gv11b.c:273:3: error: left shift count >= width of type make[2]: *** [/dvs/git/dirty/git-master_modular/tmake/artifacts/CommonRules.tmk:318: mm_gv11b.o] Error 1 This patch simply bumps the UL to ULL in BIT() to make sure that we always have at least 64 bits available for the BIT() macro.
