From 5e40704ed2c69425bcb076fb1890417ef137e6c8 Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Thu, 17 Apr 2014 13:57:37 +0100 Subject: arm: xen: implement multicall hypercall support. As part of this make the usual change to xen_ulong_t in place of unsigned long. This change has no impact on x86. The Linux definition of struct multicall_entry.result differs from the Xen definition, I think for good reasons, and used a long rather than an unsigned long. Therefore introduce a xen_long_t, which is a long on x86 architectures and a signed 64-bit integer on ARM. Use uint32_t nr_calls on x86 for consistency with the ARM definition. Build tested on amd64 and i386 builds. Runtime tested on ARM.
