Gents,

In the following kernel commits,

	9c587c05d715ca8461342c2cb3b4a67036b5c22b
	ea5abbd215b749b2ff14397a47a5e65741c67bf4
	cc890cd78acd7ab03442907d354b6af34e973cb3

the file ...$platform/mach/gpio.h is replaced with an empty file.  This 
disagrees with kernel tradition and kernel makefiles, where zero length 
files are intentionally deleted when "make distclean" is executed.

As a result, git sequences such as "make distclean ; git checkout 
master" may fail, because several files are present in the index but not 
on disk, making it appear as if modifications have been made:

	$ git checkout master
	D	arch/arm/mach-lpc32xx/include/mach/gpio.h
	D	arch/arm/mach-tegra/include/mach/gpio.h
	D	arch/arm/mach-u300/include/mach/gpio.h

An update, either (a) making these files non-zero length or (b) deleting 
the files in git would be appreciated.  Reading the commit descriptions, 
it appears (a) is the correct path?

	Jeff

Argh!

Russell already told me what to do, I just was too stupid to go back
and fix it up properly so I'm doing that now.

Thanks,

It would really help to have a hook in git which catches this at commit
time with a warning (like is possible for whitespace).  At least that
would alert folk to the problem at commit time before stuff has been
published.
