   4 Subject: [PATCH 071/203] PCI: remove ARCH_SUPPORTS_MSI kconfig option
   5
   6 Now that we have weak versions for each of the PCI MSI architecture
   7 functions, we can actually build the MSI support for all platforms,
   8 regardless of whether they provide or not architecture-specific
   9 versions of those functions. For this reason, the ARCH_SUPPORTS_MSI
  10 hidden kconfig boolean becomes useless, and this patch gets rid of it.
