Subject: [PATCH RESEND 2/3] most: 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().

This is less verbose.

This patch has been sent about 6 months ago [1].
A gentle reminder has been sent 2 months later and an A-by has been given
[2].

Another gentle reminder has been sent another 2 months later [3].

However, it has still not reached -next since then in the last 2 months.

So, I've added the A-b tag and I'm adding Andrew Morton in To:, in order to
help in the merge process.

Thanks
CJ
