Subject: [PATCH V3 0/3] drm: replace magic numbers

From: Bjorn Helgaas <bhelgaas@...gle.com>

amdgpu and radeon do a bit of mucking with the PCIe Link Control 2
register, some of it using hard-coded magic numbers.  The idea here is to
replace those with #defines.

Since v2:
  - Fix a gpu_cfg2 case in amdgpu/si.c that I had missed
  - Separate out the functional changes for better bisection (thanks,
    Michel!)
  - Add #defines in a patch by themselves (so a GPU revert wouldn't break
    other potential users)
  - Squash all the magic number -> #define changes into one patch

Since v1:
  - Add my signed-off-by and Alex's reviewed-by.

Bjorn Helgaas (3):
  PCI: Add #defines for Enter Compliance, Transmit Margin
  drm: correct Transmit Margin masks
  drm: replace numbers with PCI_EXP_LNKCTL2 definitions
