[Qemu-devel] [PATCH 1/6] qapi: fill in CpuInfoFast.arch in query-cpus-fast

[Laszlo Ersek <lersek@redhat.com>]

Commit ca230ff33f89 added added the @arch field to @CpuInfoFast, but it
failed to set the new field in qmp_query_cpus_fast(), when TARGET_S390X
was not defined. The updated @query-cpus-fast example in
"qapi-schema.json" showed "arch":"x86" only because qmp_query_cpus_fast()
calls g_malloc0() to allocate CpuInfoFast, and the CPU_INFO_ARCH_X86 enum
constant is generated with value 0.

All @arch values other than @s390 implied the @CpuInfoOther sub-struct for
@CpuInfoFast -- at the time of writing the patch --, thus no fields other
than @arch needed to be set when TARGET_S390X was not defined. Set @arch
now, by copying the corresponding assignments from qmp_query_cpus().
