The reason for the ENTRY is to get it aligned, not because it's
globally visible. It doesn't have any fallthroughs, and some cpu's
care more

At exit_intr, we GET_THREAD_INFO(%rcx) and then jump to retint_kernel
if saved CS was from kernel. But code at retint_kernel doesn't need %rcx.
Move GET_THREAD_INFO(%rcx) down, after CS check and branch.
While at it, remove "has a correct top of stack" comment.

At this label, we test whether interrupt/exception was in kernel.
If it did, we jump to preemption check. If preemption does happen
(IOW if we call preempt_schedule_irq), we go back to exit_intr.
But it's pointless, we already know that test succeeded last time,
preemption doesn't change the fact
At this location, we already have interrupts off, always.
To be more specific, we already disabled them here:

This patchset simplifies jump maze in entry_64.S a bit by moving
"retint_kernel" code block, and follows up with simplifications
which become obvious after the move.
Two labels and one define is gone
One label is no longer .global
One redundand DISABLE_INTERRUPTS is gone
A few jump and test
"retint_kernel" code block is misplaced. Since its logical continuation
is "retint_restore_args", it is more natural to place it above that label.
This also makes two jumps "short".
This change only moves code block around, without changing logic.
This enables the next simplification: making

Previous algorithm had an outer loop with the values {2,3,5,7} and an

atmel-pcm-dma.c is using the generic dmaengine framework since 95e0e07e710e

The current code expected that every LED had an unique name. This is a
legit expectation when the device tree can no be modified or extended.
But with device tree overlays this requirement can be easily broken.
