Analyze and fix the following issue in the Linux kernel code: [PATCH] x86_64: Tell VM about holes in nodes
Problem Details: Some nodes can have large holes on x86-64. This fixes problems with the VM allowing too many dirty pages because it overestimates the number of available RAM in a node. In extreme cases you can end up with all RAM filled with dirty pages which can lead to deadlocks and other nasty behaviour. This pa...

Problem Details: The acpi-cpufreq driver does a P-state get after a P-state set to verify whether set went through successfully. This test is kind of redundant as set goes throught most of the times, and the test is also expensive as a get of P-states can take a lot of time (same as a set operation) as it goes through ...
