SubjectMCE ring buffer management (Rebase)
Date
[PATCH 1/4 Rebase] x86, MCE: Provide a lock-less memory pool to save error
[PATCH 2/4 Rebase] x86, MCE: Don't use percpu for MCE workqueue/irq_work
[PATCH 3/4 Rebase] x86, MCE: Remove mce_ring for SRAO error
[PATCH 4/4 Rebase] x86, MCE: Avoid potential deadlock in MCE context

We have too many rings for different H/W error events management.
All of them can be merged into one kind of unified mechanism.
Furthermore, this management mechanism should be reliable enough
even in MCE context to avoid deadlock like calling printk in MCE
context. This patch series is used for this purpose.

P.S. One of patch has been removed since last commit because it
has been merged already.
