[OpenWrt-Devel] [PATCH] kernel: re-enable MIPS VDSO

[Kevin Darbyshire-Bryant]

kernel upstream commit 9efcaa7c4afba5628f2650a76f69c798f47eeb18 to 4.14
itself a backport of 0f02cfbc3d9e413d450d8d0fd660077c23f67eff has
resolved the cache line issues that led to us disabling VDSO by default
on MIPS.

Remove our force disable patch:
