Building a 'new' qemu machine for use with the Kernel Labs using qemuarm (versatile) as the base. A patch from kernel- cache root/arch/arm/v7-A15/ARM-LPAE-Invalidate-the-TLB-for-module- addresses-dur.patch won't apply as it already upstream. This is using 4.18.14.
I'm not seeing that exact patch in my upstream kernels. That being said, I could be missing a variant or different implementation that is doing the same thing. I just compared the linux-yocto patched function to a 5.0-rc1 tree and I still don't see the exact change in the do_translation_fault() function. What oe/yocto branch were you using ? It more sounds like the lab is out of date and has triggered a re-patching the tree, and hence the patch won't apply, since it is already on the branch. Bruce
Manually removing the patch works, but I'm not sure why this patch is still in kernel-cache.
