Subject: [PATCH 3.16 117/134] fbdev: sti: don't select CONFIG_VT
3.16.47-rc1 review patch. If anyone has any objections, please let me know.

commit 34bf129a7f068e3108dbb051b4b05674e2a270e7 upstream.
While working on another build error, I ran into several variations of
this dependency loop:
subsection "Kconfig recursive dependency limitations"
drivers/input/Kconfig:8: symbol INPUT is selected by VT
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
drivers/tty/Kconfig:12: symbol VT is selected by FB_STI
For a resolution refer to Documentation/kbuild/kconfig-language.txt

For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
drivers/of/Kconfig:4: symbol OF is selected by X86_INTEL_CE
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
arch/x86/Kconfig:523: symbol X86_INTEL_CE depends on X86_IO_APIC
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
arch/x86/Kconfig:1011: symbol X86_IO_APIC depends on X86_LOCAL_APIC
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
arch/x86/Kconfig:1005: symbol X86_LOCAL_APIC depends on X86_UP_APIC
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
arch/x86/Kconfig:980: symbol X86_UP_APIC depends on PCI_MSI
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
drivers/pci/Kconfig:11: symbol PCI_MSI is selected by AMD_IOMMU
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
drivers/iommu/Kconfig:106: symbol AMD_IOMMU depends on IOMMU_SUPPORT
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
drivers/iommu/Kconfig:5: symbol IOMMU_SUPPORT is selected by DRM_ETNAVIV
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
drivers/gpu/drm/etnaviv/Kconfig:2: symbol DRM_ETNAVIV depends on THERMAL
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
drivers/thermal/Kconfig:5: symbol THERMAL is selected by ACPI_VIDEO
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
drivers/acpi/Kconfig:183: symbol ACPI_VIDEO is selected by INPUT
This doesn't currently show up as I fixed the 'THERMAL' part of it,
but I noticed that the FB_STI dependency should not be there but
was introduced by slightly incorrect bug-fix patch that tried to
fix a link error.
Instead of selecting 'VT' to make us enter the drivers/video/console
directory at compile-time, it's sufficient to build the
drivers/video/console/sticore.c file by adding its directory
to when CONFIG_FB_STI is enabled. Alternatively, we could move the
sticore code to another directory that is always built when we
have at STI_CONSOLE or FB_STI enabled.
