* powerpc: Add configurable -Werror for arch/powerpcMichael Ellerman2009-06-169-0/+33
| | | | | | | | | | | | | | | | | | | | Add the option to build the code under arch/powerpc with -Werror. The intention is to make it harder for people to inadvertantly introduce warnings in the arch/powerpc code. It needs to be configurable so that if a warning is introduced, people can easily work around it while it's being fixed. The option is a negative, ie. don't enable -Werror, so that it will be turned on for allyes and allmodconfig builds. The default is n, in the hope that developers will build with -Werror, that will probably lead to some build breaks, I am prepared to be flamed. It's not enabled for math-emu, which is a steaming pile of warnings. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* of_serial: Add UPF_FIXED_TYPE flagDave Mitchell2009-06-161-1/+1
| | | | | | | | | | This patch adds the UPF_FIXED_TYPE flag which will bypass the 8250's autoconfig probe for uart type. The uart type identified by the of_serial's parse of the flat device tree will be utilized as defined.

* powerpc: Introduce macro spin_event_timeout()Timur Tabi2009-06-161-0/+36
| | | | | | | | | | | | | | | | 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.

* powerpc/mpc83xx: Fix usb mux setup for mpc834xPeter Korsgaard2009-06-156-11/+11
| | | | | | | | | | | | | | | | | | | | | | usb0 and usb1 mux settings in the sicrl register were swapped (twice!) in mpc834x_usb_cfg(), leading to various strange issues with fsl-ehci and full speed devices. The USB port config on mpc834x is done using 2 muxes: Port 0 is always used for MPH port 0, and port 1 can either be used for MPH port 1 or DR (unless DR uses UTMI phy or OTG, then it uses both ports) - See 8349 RM figure 1-4.. mpc8349_usb_cfg() had this inverted for the DR, and it also had the bit positions of the usb0 / usb1 mux settings swapped. It would basically 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, even though that configuration is physically invalid. Instead fix mpc8349_usb_cfg() and adjust the dts files to match reality. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | 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 macroPaul Mackerras2009-06-152-5/+4
| | | | | | | | | | | | | | | | | | | | On 32-bit non-Book E, local_irq_restore() turns into just mtmsr(), which doesn't currently have a compiler memory barrier. This means 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 hw_irq.h are now redundant, so this removes them.
