linux-next: manual merge of the header_cleanup tree with the tip tree

linux-next: manual merge of the header_cleanup tree with the tip tree

[Stephen Rothwell]

Hi all,

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

  arch/x86/include/asm/percpu.h

between commit:

  0e3703630bd3 ("x86/percpu: Fix "const_pcpu_hot" version generation failure")

from the tip tree and commit:

  863cc83ddcf8 ("Kill unnecessary kernel.h include")

from the header_cleanup 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 header_cleanup tree with the tip tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1151 bytes --]

Hi all,

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

  arch/x86/include/asm/paravirt_types.h

between commit:

  f7af6977621a ("x86/paravirt: Remove no longer needed paravirt patching code")

from the tip tree and commit:

  9483c05522c6 ("arch/x86: fix missing includes/forward declarations")

from the header_cleanup tree.

I fixed it up (I think, 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.
