Current code missed disabling interrupts before free irq which is shared.

Notice below comments for function free_irq (kernel/irq/manage.c):
On a shared IRQ the caller must ensure the interrupt is disabled
on the card it drives before calling this function.

Original code has below issue during suspend/resume when multiple SD
hosts share the same IRQ:
1. Assume there are two hosts (host1 for emmc while host2 for sd) share
the same mmc irq.
2. When system suspend, host2 will be suspended before host1.
So the sequence is below:
step1: irq handler for host2 removed ->
step2: irq handler for host1 removed and irq disabled ->
... system suspended ...
... system resumed ...
step3: irq enabled and the irq handler for host1 restored ->
step4: irq handler for host2 restored
3. So there is the buggy time slot that the irq is enabled but the irq
handler for host2 is removed. Then host2 interrupt can be triggered
but can't be handled at that moment.

8 years agommc: fix async request mechanism for sequential read scenarios
Konstantin Dorfman [Mon, 14 Jan 2013 19:28:17 +0000 (14:28 -0500)]
mmc: fix async request mechanism for sequential read scenarios

When current request is running on the bus and if next request fetched
by mmcqd is NULL, mmc context (mmcqd thread) gets blocked until the
current request completes. This means that if new request comes in while
the mmcqd thread is blocked, this new request can not be prepared in
parallel to current ongoing request. This may result in delaying the new
request execution and increase it's latency.

This change allows to wake up the MMC thread on new request arrival.
Now once the MMC thread is woken up, a new request can be fetched and
prepared in parallel to the current running request which means this new
request can be started immediately after the current running request
completes.

With this change read throughput is improved by 16%.
