powerpc: Introduce macro spin_event_timeout()
The macro spin_event_timeout() takes a condition and timeout value
(in microseconds) as parameters. It spins until either the condition is true
or the timeout expires. It returns the result of the condition when the loop
was terminated.
This primary purpose of this macro is to poll on a hardware register until a
status bit changes. The timeout ensures that the loop still terminates if the
bit doesn't change as expected. This macro makes it easier for driver
developers to perform this kind of operation properly.

The USB port config on mpc834x is done using 2 muxes: Port 0 is always

(unless DR uses UTMI phy or OTG, then it uses both ports) - See 8349 RM

mpc8349_usb_cfg() had this inverted for the DR, and it also had the bit

work if you specified port1 instead of port0 for the MPH controller (and
happened to use ULPI phys), which is what all the 834x dts have done,

Many processor architectures have no 64-bit atomic instructions, but
we need atomic64_t in order to support the perf_counter subsystem.
This adds an implementation of 64-bit atomic operations using hashed
spinlocks to provide atomicity. For each atomic operation, the address
of the atomic64_t variable is hashed to an index into an array of 16
spinlocks. That spinlock is taken (with interrupts disabled) around the
operation, which can then be coded non-atomically within the lock.
On UP, all the spinlock manipulation goes away and we simply disable
interrupts around each operation. In fact gcc eliminates the whole
atomic64_lock variable as well.

powerpc: Add compiler memory barrier to mtmsr macro
On 32-bit non-Book E, local_irq_restore() turns into just mtmsr(),

that accesses to memory inside a local_irq_save/restore section,
or a spin_lock_irqsave/spin_unlock_irqrestore section on UP, can
be reordered by the compiler to occur outside that section.
To fix this, this adds a compiler memory barrier to mtmsr for both
32-bit and 64-bit. Having a compiler memory barrier in mtmsr makes
sense because it will almost always be changing something about the
context in which memory accesses are done, so in general we don't want
memory accesses getting moved from one side of an mtmsr to the other.
With the barrier in mtmsr(), some of the explicit barriers in

When both MSI-X and legacy INTx fail to generate an interrupt, the
driver frees the MSI-X interrupts twice. Fix this by clearing the
have_irq flag for the MSI-X interrupts when they are freed the first
time. This is the same bug that was reported in ib_mthca by Yinghai
Lu <yhlu.kernel@gmail.com>.

[ARM] 5545/2: add flush_kernel_dcache_page() for ARM
Without this, the default implementation is a no op which is completely
wrong with a VIVT cache, and usage of sg_copy_buffer() produces
unpredictable results.

IB/mthca: Don't double-free IRQs when falling back from MSI-X to INTx

mmc_block: do not DMA to stack
In the write recovery routine, the data to get from the card
is allocated from the stack. The DMA mapping documentation says
explicitly stack memory is not mappable by any of the DMA calls.
Change to using kmalloc() to allocate the memory for the result
from the card and then free it once we've finished with the
transaction.
