Revert "drm/nouveau: add kconfig option to turn off nouveau legacy contexts. (v3)"
This reverts commit 140ae656e3b7476719a2b15b96527c73c5acf90b which is
commit b30a43ac7132cdda833ac4b13dd1ebd35ace14b7 upstream.
Sven reports:
Commit 1e07d63749 ("drm/nouveau: add kconfig option to turn off nouveau
legacy contexts. (v3)") has caused a build failure for me when I
actually tried that option (CONFIG_NOUVEAU_LEGACY_CTX_SUPPORT=n):
,----
| Kernel: arch/x86/boot/bzImage is ready (#1)
| Building modules, stage 2.
| MODPOST 290 modules
| ERROR: "drm_legacy_mmap" [drivers/gpu/drm/nouveau/nouveau.ko] undefined!
| scripts/Makefile.modpost:91: recipe for target '__modpost' failed
`----
Upstream does not have that problem, as commit bed2dd8421 ("drm/ttm:
Quick-test mmap offset in ttm_bo_mmap()") has removed the use of
drm_legacy_mmap from nouveau_ttm.c. Unfortunately that commit does not
apply in 5.1.9.
The ensuing discussion proposed a number of one-off patches, but no
solid agreement was made, so just revert the commit for now to get
people's systems building again.
