Subject: [PATCH] ARM: hyp-stub: Fix Thumb-2 compilation
Date: Thu, 20 Apr 2017 11:16:20 +0100	[thread overview]
Message-ID: <20170420101620.1368-1-marc.zyngier@arm.com> (raw)

The assembler defaults to emiting the short form of ADR, leading
to an out-of-range immediate. Using the wide version solves this
issue.

Fixes: bc845e4fbbbb ("ARM: KVM: Implement HVC_RESET_VECTORS stub hypercall in the init code")
Reported-by: Arnd Bergmann <arnd@arndb.de>
Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
