Resolving conflicts

[Wink Saville <wink@saville.com>]

Sorry to be so ignorant, but I just updated to 2.6.19 using:

   git-checkout master
   git-pull

   ...
   sound/usb/usbaudio.c                          |    3
   usr/Makefile                                  |    2
   92 files changed, 888 insertions(+), 371 deletions(-)

   create mode 100644 arch/um/os-Linux/execvp.c
   create mode 100644 include/asm-arm/mach/udc_pxa2xx.h

All seemed to go I then moved back to my branch and pulled from master to my branch:

   git-checkout ace
   git-pull . master

But that failed:

   Trying really trivial in-index merge...
   fatal: Merge requires file-level merging
   Nope.

   Auto-merging kernel/fork.c
   CONFLICT (content): Merge conflict in kernel/fork.c
   Auto-merging kernel/spinlock.c
   CONFLICT (content): Merge conflict in kernel/spinlock.c

   Automatic merge failed; fix conflicts and then commit the result.

I then searched the net for how to resolve conflicts, seems you
should start by doing a git-diff, so I did and I get this:

   diff --cc kernel/fork.c
   index d74b4a5,8cdd3e7..0000000
   --- a/kernel/fork.c
   +++ b/kernel/fork.c
   diff --cc kernel/spinlock.c
   index f4d1718,2c6c2bf..0000000
   --- a/kernel/spinlock.c
   +++ b/kernel/spinlock.c

And git-status shows:

   # On branch refs/heads/ace
   #
   # Updated but not checked in:
   #   (will commit)
   #
   #       modified: Documentation/rtc.txt
   #       modified: Makefile
   #       modified: arch/arm/configs/assabet_defconfig
   #       modified: arch/arm/configs/cerfcube_defconfig
   ......
   #       modified: sound/usb/usbaudio.c
   #       modified: usr/Makefile
   #
   #
   # Changed but not updated:
   #   (use git-update-index to mark for commit)
   #
   #       unmerged: kernel/fork.c
   #       modified: kernel/fork.c
   #       unmerged: kernel/spinlock.c
   #       modified: kernel/spinlock.c
   #

So what have I done wrong?
Did the pull complete and I just need to resolve this or
do I need to redo the git-pull?

Thanks,
