linux master cannot compile successfully

[Kinka Huang]

Hey,
I just pull linux-master and checkout tag v3.17-rc5. I think 
linux-master should always compiles successfully, but it seems I am wrong?
I got the error:

In file included from drivers/gpu/drm/nouveau/core/core/client.c:29:0:
drivers/gpu/drm/nouveau/core/include/nvif/unpack.h:1:1: error: expected 
identifier or ?(? before ?.? token
  ../../../nvif/unpack.h
  ^
drivers/gpu/drm/nouveau/core/core/client.c:43:29: error: field ?v0? has 
incomplete type
    struct nvif_notify_rep_v0 v0;
                              ^
etc...

The file drivers/gpu/drm/nouveau/core/include/nvif/unpack.h
should contain just "../../../nvif/unpack.h"? Why? Is it just an error 
or I did something wrong?

Thanks.

Your tree is somehow corrupted.  The first few lines of my copy of unpack.h
look like this:

#ifndef __NVIF_UNPACK_H__
#define __NVIF_UNPACK_H__

#define nvif_unvers(d) ({                                                       
and 'git log drivers/gpu/drm/nouveau/core/include/nvif/unpack.h' reports
it's never been touched since initial creation:

commit 79ca27706a034b683196c85f5c6901b78e5ab8f0
Author: Ben Skeggs <bskeggs@redhat.com>

    drm/nouveau/core: rework event interface

Not sure what happened to it - if you're doing this on a laptop, one
possibility is the lack of ECC memory causing a single-bit error in a
pointer, causing wrong blocks to have been written to the disk.  Other
hardware or software errors are also still on the table.

@sudip, I used the same config file before this tag and no problem.
The whole config file maybe too much, can you tell me which part to
post? I will post the file later.

@valdis, I am doing that on a laptop. I try to get back the file by
deleting unpack.h and checkout, but the same content remains. And `git
status` or `git log` doesn't show any changes of file "unpack.h" . One
suspicious action is that, I ever moved the whole directory of
linux-master from ext4 to a ntfs driver and compiled it by mounting it
back.
So, there is some way to get the right content back?

That's weird indeed.

Did the problem start when you did that, or was that an attempt at recovery?

You may have to resort to 'git clone' from git.kernel.org.

Or restore from backups. You *do* have backups, right? :)
