From 994a04a20b03128838ec0250a0e266aab24d23f1 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 8 Nov 2021 12:13:41 +0100 Subject: thermal: int340x: Limit Kconfig to 64-bit 32-bit processors cannot generally access 64-bit MMIO registers atomically, and it is unknown in which order the two halves of this registers would need to be read: drivers/thermal/intel/int340x_thermal/processor_thermal_mbox.c: In function 'send_mbox_cmd': drivers/thermal/intel/int340x_thermal/processor_thermal_mbox.c:79:37: error: implicit declaration of function 'readq'; did you mean 'readl'? [-Werror=implicit-function-declaration] 79 | *cmd_resp = readq((void __iomem *) (proc_priv->mmio_base + MBOX_OFFSET_DATA)); | ^~~~~ | readl The driver already does not build for anything other than x86, so limit it further to x86-64.
