Subject: [PATCH V2 02/13] arm64/kvm: Fix assembler compatibility of macros
Date: Wed, 10 Sep 2014 11:04:46 -0700	[thread overview]
Message-ID: <1410372286.11440.22.camel@smoke> (raw)
In-Reply-To: <bc4abc340eaa4da448f62326a134fabfb5a2a875.1410302383.git.geoff@infradead.org>

Some of the macros defined in kvm_arm.h are useful in the exception vector
routines, but they are not compatible with the assembler.  Change the
definition of ESR_EL2_ISS to be compatible.

Fixes build errors like these when using kvm_arm.h in assembly
source files:

  Error: unexpected characters following instruction at operand 3 -- `and x0,x1,#((1U<<25)-1)'
