[PATCHv3 0/6] make vendor specific subdirectory inclusion conditional

[Rolf Eike Beer]

[-- Attachment #1: Type: text/plain, Size: 1119 bytes --]

I found it strange that the vendor specific subdirectories were unconditionally 
added. Everything in these directories obviously depends on the specific Kconfig 
option. This series cleans this up by making the directory itself depend on 
the respective option which looks more natural to me.

I must confess that I am too lazy to find a good solution for the "arm/" 
directory, so I left it as is.

Regards,

Eike

[PATCH 5/6] iommu: make inclusion of arm/arm-smmu-v3 directory conditional

[Rolf Eike Beer]

Nothing in there is active if CONFIG_ARM_SMMU_V3 is not enabled, so the whole
directory can depend on that switch as well.
