Jason Gunthorpe 6a3d5fda2c iommupt: Make pt_feature() always_inline ... gcc 8.5 on powerpc does not automatically inline these functions even though they evaluate to constants in key cases. Since the constant propagation is essential for some code elimination and built-time checks this causes a build failure: ERROR: modpost: "__pt_no_sw_bit" [drivers/iommu/generic_pt/fmt/iommu_amdv1.ko] undefined! Caused by this: if (pts_feature(&pts, PT_FEAT_DMA_INCOHERENT) && !pt_test_sw_bit_acquire(&pts, SW_BIT_CACHE_FLUSH_DONE)) flush_writes_item(&pts); Where pts_feature() evaluates to a constant false. Mark them as __always_inline to force it to evaluate to a constant and trigger the code elimination. Fixes: 7c5b184db7 ("genpt: Generic Page Table base API") Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202512230720.9y9DtWIo-lkp@intel.com/ Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>		2026-01-10 10:50:45 +01:00
