Sorry, I did not know/realize, and unfortunately "he" is the grammatical
default in English, although the singular they is fortunately making a comeback.
I stand corrected, through. Please acer my apologies.

Yes, that we can move, of course.

This patch add the time support for 32 bit a VDSO to a 32 bit kernel.
For 32 bit programs running on a 32 bit kernel, the same mechanism is
used as for 64 bit programs running on a 64 bit kernel.
