ps3: Introduce CONFIG_PS3_ADVANCED, as suggested by Roman Zippel, and use it to control questions about PS3 subsystems that may not be obvious for the casual user.

2007-03-02[PATCH] uml: host VDSO fixJeff Dike1-0/+3
This fixes a problem seen by a number of people running UML on newer host kernels. init would hang with an infinite segfault loop. It turns out that the host kernel was providing a AT_SYSINFO_EHDR of 0xffffe000, which faked UML into believing that the host VDSO page could be reused. However, AT_SYSINFO pointed into the middle of the address space, and was unmapped as a result. Because UML was providing AT_SYSINFO_EHDR and AT_SYSINFO to its own processes, these would branch to nowhere when trying to use the VDSO. The fix is to also check the location of AT_SYSINFO when deciding whether to use the host's VDSO.

2007-03-02[PATCH] uml: fix host LDT lookup initialization locking, try 2Jeff Dike1-12/+24
Add some locking to host_ldt_entries to prevent racing when reading LDT information from the host. The locking is somewhat more careful than my previous attempt. Now, only the check of host_ldt_entries is locked. The lock is dropped immediately afterwards, and if the LDT needs initializing, that (and the memory allocations needed) proceed outside the lock. Also fixed some style violations.

2007-02-28[PATCH] x86_64/i386 irq: Fix !CONFIG_SMP compilationEric W. Biederman2-6/+0
When removing set_native_irq I missed the fact that it was called in a couple of places that were compiled even when SMP support is disabled. And since the irq_desc[].affinity field only exists in SMP things broke. Thanks to Simon Arlott <simon@arlott.org> for spotting this. There are a couple of ways to fix this but the simplest one is to just remove the assignments. The affinity field is only used to display a value to the user, and nothing on either i386 or x86_64 reads it or depends on it being any particlua value, so skipping the assignment is safe. The assignment that is being removed is just for the initial affinity value before the user explicitly sets it. The irq_desc array initializes this field to CPU_MASK_ALL so the field is initialized to a reasonable value in the SMP case without being set. Signed-off-by: Eric W.

2007-02-26[PATCH] x86_64 irq: Safely cleanup an irq after moving it.Eric W. Biederman3-6/+81
The problem: After moving an interrupt when is it safe to teardown the data structures for receiving the interrupt at the old location? With a normal pci device it is possible to issue a read to a device to flush all posted writes. This does not work for the oldest ioapics because they are on a 3-wire apic bus which is a completely different data path. For some more modern ioapics when everything is using front side bus delivery you can flush interrupts by simply issuing a read to the ioapic. For other modern ioapics emperical testing has shown that this does not work. So it appears the only reliable way to know the last of the irqs from an ioapic have been received from before the ioapic was reprogrammed is to received the first irq from the ioapic from after it was reprogrammed. Once we know the last irq message has been received from an ioapic into a local apic we then need to know that irq message has been processed through the local apics. Signed-off-by: Eric W.

Currently assign_irq_vector works mostly by side effect and returns the results of it's changes to the caller. Which makes for a lot of arguments to pass/return and confusion as to what to do if you need the status but you aren't calling assign_irq_vector.
