Subject: [drm/mgag200]  90f479ae51:  vm-scalability.median -18.8% regression

Greeting,

FYI, we noticed a -18.8% regression of vm-scalability.median due to commit:


commit: 90f479ae51afa45efab97afdde9b94b9660dd3e4 ("drm/mgag200: Replace struct mga_fbdev with generic framebuffer emulation")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next.git master

in testcase: vm-scalability
on test machine: 288 threads Intel(R) Xeon Phi(TM) CPU 7295 @ 1.50GHz with 80G memory
with following parameters:

	runtime: 300s
	size: 8T
	test: anon-cow-seq-hugetlb
	cpufreq_governor: performance

test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/



Details are as below:
