• b170bad40   s390/pci: do not read data after failed load ... Browse Code »

  If a pci load instruction fails the content of the register where the
  data is stored is possibly unchanged. Fix the inline assembly wrapper
  __pcilg to not return stale data. Additionally fix the callers of this
  function who access uninitialized variables.

  Don't let pci_load and friends crash the kernel when called with
  e.g. an invalid offset. Return -ENXIO instead.

• cbcca5d07   s390/pci: uninline instruction wrappers ... Browse Code »

  Uninline pci related instruction wrappers to de-bloat the code:
  add/remove: 15/0 grow/shrink: 2/24 up/down: 1326/-12628 (-11302)

  This is especially useful for the inlined pci read and write functions
  which are used all over the kernel. Also remove the unused __stpcifc
  while at it.
