[PATCH v7 0/5] PCI: Remove most pcim_iounmap_regions() users

From: Philipp Stanner
Date: Mon Oct 14 2024 - 03:53:50 EST


Ready for merge, all Reviews / Acks are in place.

Merge plan for this is the PCI-Tree.

After this series, only two users (net/ethernet/stmicro and
vdpa/solidrun) will remain to be ported in the subsequent merge window.
Doing them right now proved very difficult because of various conflicts
as they are currently also being reworked.

Changes in v7:
- Add Paolo's Acked-by.
(- Rebase on current master)

Changes in v6:
- Remove the patches for "vdpa: solidrun" since the maintainer seems
unwilling to review and discuss, not to mention approve, anything
that is part of a wider patch series across other subsystems.
- Change series's name to highlight that not all callers are removed
by it.

Changes in v5:
- Patch "ethernet: cavium": Re-add accidentally removed
pcim_iounmap_region(). (Me)
- Add Jens's Reviewed-by to patch "block: mtip32xx". (Jens)

Changes in v4:
- Drop the "ethernet: stmicro: [...] patch since it doesn't apply to
net-next, and making it apply to that prevents it from being
applyable to PCI ._. (Serge, me)
- Instead, deprecate pcim_iounmap_regions() and keep "ethernet:
stimicro" as the last user for now.
- ethernet: cavium: Use PTR_ERR_OR_ZERO(). (Andy)
- vdpa: solidrun (Bugfix) Correct wrong printf string (was "psnet" instead of
"snet"). (Christophe)
- vdpa: solidrun (Bugfix): Add missing blank line. (Andy)
- vdpa: solidrun (Portation): Use PTR_ERR_OR_ZERO(). (Andy)
- Apply Reviewed-by's from Andy and Xu Yilun.

Changes in v3:
- fpga/dfl-pci.c: remove now surplus wrapper around
pcim_iomap_region(). (Andy)
- block: mtip32xx: remove now surplus label. (Andy)
- vdpa: solidrun: Bugfix: Include forgotten place where stack UB
occurs. (Andy, Christophe)
- Some minor wording improvements in commit messages. (Me)

Changes in v2:
- Add a fix for the UB stack usage bug in vdap/solidrun. Separate
patch, put stable kernel on CC. (Christophe, Andy).
- Drop unnecessary pcim_release_region() in mtip32xx (Andy)
- Consequently, drop patch "PCI: Make pcim_release_region() a public
function", since there's no user anymore. (obsoletes the squash
requested by Damien).
- vdap/solidrun:
• make 'i' an 'unsigned short' (Andy, me)
• Use 'continue' to simplify loop (Andy)
• Remove leftover blank line
- Apply given Reviewed- / acked-bys (Andy, Damien, Bartosz)


Important things first:
This series is based on [1] and [2] which Bjorn Helgaas has currently
queued for v6.12 in the PCI tree.

This series shall remove pcim_iounmap_regions() in order to make way to
remove its brother, pcim_iomap_regions().

Regards,
P.
