Hi All, The iommu/vt-d code calls WARN_TAINT(... TAINT_FIRMWARE_WORKAROUND ...) in various places. Since the firmware is outside of the kernel's control this should not be using the WARN_TAINT macro for this, calling the WARN* macros based on external inputs is wrong, as there is nothing we can do to fix those external inputs and the WARN* macros are intended for things which we can fix (also see the patch commit msg).
I'm working on a patch-set which converts all in kernel uses of WARN_TAINT(... TAINT_FIRMWARE_WORKAROUND ...) to pr_warn + add_taint, but I'm sending these 2 out separately because these address the 2 most troublesome cases of the vt-d code calling WARN_TAINT() which together are responsible for over a 100 bugzilla-s in Fedora alone. Can we please get these 2 patches queued up as fixes for 5.6-rc# ?
