Subject: [PATCH 0/2] IPI numbering cleanup
Date: Fri, 18 Dec 2015 09:16:11 +0000	[thread overview]
Message-ID: <1450430173-26992-1-git-send-email-marc.zyngier@arm.com> (raw)

Daniel Thompson reported[1] that IPI_CPU_BACKTRACE failed to fire on
one of his platforms because SGI15 was already used by the secure
firmware.

In order to move this IPI to the non-secure side, this series drops
IPI_CALL_FUNC_SINGLE (which has been deprecated for a while). This
allows the last non-secure SGI to be reallocated to IPI_CPU_BACKTRACE.

       M.
