Zero-length ARM headers in git HEAD

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
