      drm/radeon/kms: move disp eng pll setup to init path · 3fa47d9e
      Alex Deucher authored
      We really only need to set it up once on init or resume
      rather than on every mode set.

      drm/radeon: finish getting bios earlier · 211fa4fc
      Igor Murzov authored
      Return a number of bytes read in radeon_atrm_get_bios_chunk() and
      properly check this value in radeon_atrm_get_bios().
      If radeon_atrm_get_bios_chunk() read less bytes then were requested,
      it means that it finished reading bios data.
      Prior to this patch, condition in radeon_atrm_get_bios() was always
      equivalent to "if (ATRM_BIOS_PAGE <= 0)", so it was always false,
      thus radeon_atrm_get_bios() was trying to read past the bios data
      wasting boot time.
      On my lenovo ideapad u455 laptop this patch drops bios reading time
      from ~5.5s to ~1.5s.

      uml: fix compile for x86-64 · 90a4c0f5

        arch/x86/um/shared/sysdep/ptrace.h:7:20: note: previous definition of 'regs_return_value' was here
      when compiling UML for x86-64.
      Stephen Rothwell root-caused it and says:

       ("Audit: push audit success and retcode
        into arch ptrace.h") (another patch that was never in linux-next :-().

      tpm: fix (ACPI S3) suspend regression · be405411
      Stefan Berger authored
      This patch fixes an (ACPI S3) suspend regression introduced in commit
       ("tpm: Introduce function to poll for result of self test")
      and occurring with an Infineon TPM and tpm_tis and tpm_infineon drivers
      The suspend problem occurred if the TPM was disabled and/or deactivated
      and therefore the TPM_PCRRead checking the result of the (asynchronous)
      self test returned an error code which then caused the tpm_tis driver to
      become inactive and this then seemed to have negatively influenced the
      suspend support by the tpm_infineon driver...  Besides that the tpm_tis
      drive may stay active even if the TPM is disabled and/or deactivated.

      The type of 'make_request_fn' changed in 5a7bbad2
       ("block: remove
      support for bio remapping from ->make_request"), but the merge of the
      nvme driver didn't take that into account, and as a result the driver
      would compile with a warning:
