x86: Rename e820_table_* to pgt_buf_*
e820_table_{start|end|top}, which are used to buffer page table allocation during early boot, are now derived from memblock and don't have much to do with e820. Change the names so that they reflect what they're used for. This patch doesn't introduce any behavior change. -v2: Ingo found that earlier patch "x86: Use early pre-allocated page table buffer top-down" caused crash on 32bit and needed to be dropped. This patch was updated to reflect the change. -tj: Updated commit description. Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Tejun Heo <tj@kernel.org>
