linux-next: manual merge of the parisc-hd tree with the asm-generic tree

linux-next: manual merge of the parisc-hd tree with the asm-generic tree

[Stephen Rothwell]

Hi all,

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

  arch/parisc/lib/memcpy.c

between commit:

  967747bbc084 ("uaccess: remove CONFIG_SET_FS")

from the asm-generic tree and commit:

  d4a767ea8b0e ("parisc: Use constants to encode the space registers like SR_KERNEL")

from the parisc-hd tree.

I fixed it up (I just used the latter) 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 asm-generic tree and commit

  360bd6c65807 ("parisc: Use constants to encode the space registers like SR_KERNEL")

in Linus' tree.

Arnd,
can you please drop the changes in your asm-generic tree for
arch/parisc/lib/memcpy.c
They are not needed any more.

Sorry I missed that earlier when the conflict happened originally.

I can't really rebase my changes on top of your tree now, and just dropping
the change without a rebase would break mine. I'll make sure to mention
the conflict in the pull request then and have Linus resolve it.

I dropped the patch from the parisc-hd tree for now - 
it needs more work and will not be part of the next merge window.

Thanks,

This is just a reminder that this conflict still exists.

linux-next: manual merge of the parisc-hd tree with the asm-generic tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 755 bytes --]

Hi all,

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

  arch/parisc/kernel/time.c

between commit:

  686092e7daaa ("parisc: use legacy_timer_tick")

from the asm-generic tree and commit:

  3b7ab4a74a2d ("parisc: Switch to clockevent based timers")

from the parisc-hd tree.

I fixed it up (I effectively reverted the former commit) 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.
