[ Upstream commit 01acaf3aa75e1641442cc23d8fe0a7bb4226efb1 ]
vmpic_msi_feature is only used conditionally, which triggers a rare
-Werror=unused-const-variable= warning with gcc:
arch/powerpc/sysdev/fsl_msi.c:567:37: error: 'vmpic_msi_feature' defined but not used [-Werror=unused-const-variable=]
567 | static const struct fsl_msi_feature vmpic_msi_feature =
Hide this one in the same #ifdef as the reference so we can turn on
the warning by default.

[ Upstream commit ff7a60ab1e065257a0e467c13b519f4debcd7fcf ]
Sparse reports a size mismatch in the endian swap. The Opal
implementation[1] passes the value as a __be64, and the receiving
variable out_qsize is a u64, so the use of be32_to_cpu() appears to be
an error.
