  "message": "x86/vdso: Fake 32bit VDSO build on 64bit compile for vgetcpu\n\nThe 64bit register constrains in __arch_hweight64() cannot be\nfulfilled in a 32-bit build. The function is only declared but not used\nwithin vclock_gettime.c and gcc does not care. LLVM complains and\naborts. Reportedly because it validates extended asm even if latter\nwould get compiled out, see\n\n  https://lore.kernel.org/r/Y%2BJ%2BUQ1vAKr6RHuH@dev-arch.thelio-3990X\n\ni.e., a long standing design difference between gcc and LLVM.\n\nMove the \"fake a 32 bit kernel configuration\" bits from vclock_gettime.c\ninto a common header file. Use this from vclock_gettime.c and vgetcpu.c.\n\n  [ bp: Add background info from Nathan. ]\n\nFixes: 92d33063c081a (\"x86/vdso: Provide getcpu for x86-32.\")\nReported-by: kernel test robot \u003clkp@intel.com\u003e\nSigned-off-by: Sebastian Andrzej Siewior \u003cbigeasy@linutronix.de\u003e\nSigned-off-by: Borislav Petkov (AMD) \u003cbp@alien8.de\u003e\nLink: https://lore.kernel.org/r/Y+IsCWQdXEr8d9Vy@linutronix.de\n",
