linux-next: manual merge of the pm tree with the risc-v tree

linux-next: manual merge of the pm tree with the risc-v tree

[Stephen Rothwell]

Hi all,

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

  arch/riscv/include/asm/irq.h

between commit:

  f15c21a3de1b ("RISC-V: Enable IPI CPU Backtrace")

from the risc-v tree and commit:

  f8619b66bdb1 ("irqchip/riscv-intc: Add ACPI support for AIA")

from the pm 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.

This is now a conflict between the risc-v tree and Linus' tree.

linux-next: manual merge of the pm tree with the risc-v tree

[-- Attachment #1: Type: text/plain, Size: 1739 bytes --]

Hi all,

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

  arch/riscv/include/asm/acpi.h

between commit:

  286109eaee3d4 ("riscv: acpi: Handle LPI architectural context loss flags")

from the risc-v tree and commit:

  704ce0039a629 ("ACPI: irq: Move RISC-V interrupt controllers autodep to ACPI IRQ code")

from the pm 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.
