Subject: [PATCH RESEND 3/3] proc: Remove usage of the deprecated ida_simple_xx() API
ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().
Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_max() is inclusive. So a -1 has been added when needed.

This patch has been sent about 5 months ago [1] and has been A-by just a
few minutes after.
A gentle reminder has been sent 3 months later [2].
However, it has still not reached -next since then in the last 2 months.
So, I've added the R-b tag and I'm adding Andrew Morton in To:, in order to
help in the merge process.
Thanks
CJ
