      gpu/radeon: Set flag to indicate broken 64-bit MSI · 91ed6fd2
      Benjamin Herrenschmidt 提交于
      Some radeon ASICs don't support all 64 address bits of MSIs despite
      advertising support for 64-bit MSIs in their configuration space.
      
      This breaks on systems such as IBM POWER7/8, where 64-bit MSIs can
      be assigned with some of the high address bits set.
      
      This makes use of the newly introduced "no_64bit_msi" flag in structure
      pci_dev to allow the MSI allocation code to fallback to 32-bit MSIs
      on those adapters.

      Adding Alex's review tag. Patch to the driver is identical to the
      reviewed one, I dropped the arch/powerpc hunk rewrote the subject
      and cset comment.
