* memory barrier: adding smp_mb__after_lockJiri Olsa2009-07-091-0/+4
| | | | | | | | | | | | Adding smp_mb__after_lock define to be used as a smp_mb call after a lock. Making it nop for x86, since {read|write|spin}_lock() on x86 are full memory barriers.

* Revert "PCI: use ACPI _CRS data by default"Linus Torvalds2009-06-244-5/+5
| | | | | | | | | | | | | | This reverts commit 9e9f46c44e487af0a82eb61b624553e2f7118f5b. Quoting from the commit message: "At this point, it seems to solve more problems than it causes, so let's try using it by default. It's an easy revert if it ends up causing trouble." And guess what? The _CRS code causes trouble. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * MIPS: SMP: Allow suspend and hibernation if CPU hotplug is availableRalf Baechle2009-06-241-2/+2
| | | | | | | | | | | | | | | | The SMP implementation of suspend and hibernate depends on CPU hotplugging. In the past we didn't have CPU hotplug so suspend and hibernation were not possible on SMP systems. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
| * MIPS: Add arch generic CPU hotplugRalf Baechle2009-06-247-7/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | Each platform has to add support for CPU hotplugging itself by providing suitable definitions for the cpu_disable and cpu_die of the smp_ops methods and setting SYS_SUPPORTS_HOTPLUG_CPU. A platform should only set SYS_SUPPORTS_HOTPLUG_CPU once all it's smp_ops definitions have the necessary changes. This patch contains the changes to the dummy smp_ops definition for uni-processor systems. Parts of the code contributed by Cavium Inc. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| | | | | | | | | | | | | | | | | | | | We can't perform any flushes on SMP from swsusp_arch_resume because interrupts are disabled. A cross-CPU flush is unnecessary anyway because all but the local CPU have already been disabled. A local flush is not needed either because we didn't change any mappings. So just delete the code.

Without source-id checking for interrupt remapping , a rouge guest/VM with assigned devices can launch interrupt attacks to bring down anothe guest/VM or the VMM itself. This patch adds source-id checking for interrupt remapping, and then really isolates interrupts for guests/VMs with assigned devices. Because PCI subsystem is not initialized yet when set up IOAPIC entries, use read_pci_config_byte to access PCI config space directly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We defined SDRAM_tRAS to TRAS_4, but then wrongly defined SDRAM_tRAS_num to 3. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * | | | Blackfin: unify memory map headersMike Frysinger2009-06-2216-350/+145
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many aspects of the Blackfin memory map is exactly the same across all variants. Rather than copy and paste all of these duplicated values in each header, unify all of these into the common Blackfin memory map header file. In the process, push down BF561 SMP specific stuff to the BF561 specific header to keep the noise down. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * | | | Blackfin: stick the CPU name into boot image nameRobin Getz2009-06-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than use "Linux" in the boot image name (as this is redundant -- the image type is already set to "linux"), use the CPU name. This makes it fairly obvious when a wrong image is accidentally booted. Otherwise there is no kernel output and you waste time scratching your head wondering wtf just happened.

| * | | | Blackfin: decouple unrelated cache settings to get exact behaviorJie Zhang2009-06-2211-81/+176
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current cache options don't really represent the hardware features. They end up setting different aspects of the hardware so that the end result is to turn on/off the cache. Unfortunately, when we hit cache problems with the hardware, it's difficult to test different settings to root cause the problem. The current settings also don't cleanly allow for different caching behaviors with different regions of memory. So split the configure options such that they properly reflect the settings that are applied to the hardware.
