linux-next: manual merge of the cxl tree with the pm tree

linux-next: manual merge of the cxl tree with the pm tree

Hi all,

Today's linux-next merge of the cxl tree got a conflict in:

  drivers/pci/pcie/aer.c

between commit:

  e2abc47a5a1a ("ACPI: APEI: Fix AER info corruption when error status data has multiple sections")

from the pm tree and commit:

  6777877eb7a3 ("PCI/AER: Refactor cper_print_aer() for use by CXL driver module")

from the cxl tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

linux-next: manual merge of the cxl tree with the pm tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 3298 bytes --]

Hi all,

Today's linux-next merge of the cxl tree got a conflict in:

  lib/fw_table.c

between commit:

  4b3805daaacb ("ACPI: tables: Correct and clean up the logic of acpi_parse_entries_array()")

from the pm tree and commit:

  60e43fe5285e ("lib/firmware_table: tables: Add CDAT table parsing support")

from the cxl tree.

Dan, thanks again for the heads up.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating

linux-next: manual merge of the cxl tree with the pm tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1830 bytes --]

Hi all,

Today's linux-next merge of the cxl tree got a conflict in:

  include/linux/acpi.h

between commit:

  f47507988145 ("thermal: ACPI: Move the ACPI thermal library to drivers/acpi/")

from the pm tree and commit:

  ca53543d8e34 ("acpi: numa: Add helper function to retrieve the performance attributes")

from the cxl tree.

Dan, thanks for the heads up.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
