linux-next: manual merge of the akpm-current tree with the parisc-hd tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1450 bytes --]

Hi all,

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

  arch/parisc/mm/init.c

between commit:

  98429dded340 ("parisc: Enable SPARSEMEM_VMEMMAP")

from the parisc-hd tree and commit:

  2e5adbd9e97a ("initramfs: provide a generic free_initrd_mem implementation")

from the akpm-current 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.

These simple conflicts are not really a problem (Linus is happy to cope
with them).  I just send these messages out for consistency and
openness.

Thanks Stephen!

@Andrew, I can push the addition of those two MADV_ constants to 
arch/parisc/include/uapi/asm/mman.h through the parisc git tree, 
if you drop this part from your patchset.
Otherwise, just let me know how you prefer to solve this merge conflict.

Just a reminder that the above conflict still exists.

linux-next: manual merge of the akpm-current tree with the parisc-hd tree

Hi Andrew,

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

  arch/parisc/include/uapi/asm/mman.h

I fixed it up (see below) and can carry the fix as necessary. This

linux-next: manual merge of the akpm-current tree with the parisc-hd tree

[Stephen Rothwell]

Hi Andrew,

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

  arch/parisc/Kconfig

between commit:

  b5d5cf2b8a68 ("parisc: Drop BROKEN_RODATA config option")

from the parisc-hd tree and commit:

  7b4d24d8c01d ("atomic64: no need for CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE")

from the akpm-current 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.

Hi Andrew,

Today's linux-next merge of the akpm-current tree got a conflict in
arch/parisc/include/asm/Kbuild between commit 476840458128 ("parisc:
Eliminate sg_virt_addr() and private scatterlist.h") from the parisc-hd
tree and commit e494f4a463cd ("parisc: switch to using asm-generic for
seccomp.h") from the akpm-current tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
