OOT build fails on x86_64 due to missing asm/unisd_64.h

OOT build fails on x86_64 due to missing asm/unisd_64.h

[Peter Wu]

Hi,

When I tried to build v3.11-rc1-8-g47188d3 out-of-tree, I get an error about a
missing asm/unistd_64.h file. The full build output (`git clean -xfd` was ran
before baking the kernel):

/home/me/Linux-src/build$ make O=$PWD -C ../linux -j8
make: Entering directory `/home/me/Linux-src/linux'

As a workaround, I rsync the files that are placed in the source tree:

~/Linux-src/linux/arch/x86/include/generated$ rsync -av . /tmp/build/arch/x86/include/generated/
sending incremental file list
./
asm/
asm/syscalls_32.h
uapi/
uapi/asm/
uapi/asm/unistd_32.h
uapi/asm/unistd_64.h                                                                                                                                                                                                             
uapi/asm/unistd_x32.h


I have encountered this error some releases back, and some others reported
this before[1]. If you need more details (.config?), please ask.

Regards,
Peter

In a clean directory?

That's a fast reply! While trying to reproduce after sending out the mail, I
noticed this line:
$ (cd ~/Linux-src/linux/;git clean -xfd)
Removing arch/x86/include/generated/
warning: failed to remove arch/x86/include/generated/

Somehow that directory got root owned and I was unable to remove it without
using root power. After removing it, the build completes succesfully.

Sorry for the noise!

Thanks,
Peter
