Drop static on a local variable, when the variable is initialized before any possible use. Thus, the static has no benefit.

This patch allows the user to disable write combined mapping of the efifb framebuffer console using an nowc option. A customer noticed major slowdowns while logging to the console with write combining enabled, on other tasks running on the same CPU. (10x or greater slow down on all other cores on the same CPU as is doing the logging). I reproduced this on a machine with dual CPUs. Intel(R) Xeon(R) CPU E5-2609 v3 @ 1.90GHz (6 core) I wrote a test that just mmaps the pci bar and writes to it in a loop, while this was running in the background one a single core with (taskset -c 1), building a kernel up to init/version.o (taskset -c 8) went from 13s to 133s or so. I've yet to explain why this occurs or what is going wrong I haven't managed to find a perf command that in any way gives insight into this. 11,885,070,715 instructions # 1.39 insns per cycle vs 12,082,592,342 instructions # 0.13 insns per cy... -
