2010-05-21powerpc/rtasd: Don't start event scan if scan rate is zeroMichael Ellerman
There appear to be Pegasos systems which have the rtas-event-scan RTAS tokens, but on which the event scan always fails. They also have an event-scan-rate property containing 0, which means call event scan 0 times per minute. So interpret a scan rate of 0 to mean don't scan at all. This fixes the problem on the Pegasos machines and makes sense as well. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2010-05-20powerpc,kgdb: Introduce low level trap catchingJason Wessel
The only way the debugger can handle a trap in inside rcu_lock, notify_die, or atomic_notifier_call_chain without a recursive fault is to allow the kernel debugger to handle the exception first in program_check_exception(). The other change here is to make sure that kgdb_handle_exception() is called with correct parameters when catching an oops, because kdb needs to know if the entry was an oops, single step, or breakpoint exception.

2010-05-20kgdb: core changes to support kdbJason Wessel
These are the minimum changes to the kgdb core in order to enable an API to connect a new front end (kdb) to the debug core. This patch introduces the dbg_kdb_mode variable controls where the user level I/O is routed. It will be routed to the gdbstub (kgdb) or to the kdb front end which is a simple shell available over the kgdboc connection. You can switch back and forth between kdb or the gdb stub mode of operation dynamically. From gdb stub mode you can blindly type "$3#33", or from the kdb mode you can enter "kgdb" to switch to the gdb stub. The logic in the debug core depends on kdb to look for the typical gdb connection sequences and return immediately with KGDB_PASS_EVENT if a gdb serial command sequence is detected. That should allow a reasonably seamless transition between kdb -> gdb without leaving the kernel exception state. The two gdb serial queries that kdb is responsible for detecting are the "?" and "qSupported" packets.

2010-05-19panic: Allow warnings to set different taint flagsBen Hutchings
WARN() is used in some places to report firmware or hardware bugs that are then worked-around. These bugs do not affect the stability of the kernel and should not set the flag for TAINT_WARN. To allow for this, add WARN_TAINT() and WARN_TAINT_ONCE() macros that take a taint number as argument. Architectures that implement warnings using trap instructions instead of calls to warn_slowpath_*() now implement __WARN_TAINT(taint) instead of __WARN().

This patch eliminates the node pointer from struct of_device and the of_node (or prom_node) pointer from struct dev_archdata since the node pointer is now part of struct device proper when CONFIG_OF is set, and all users of the old pointer locations have already been converted over to use device->of_node.

2010-05-17powerpc/fsl-booke: Move loadcam_entry back to asm code to fix SMP ftraceKumar Gala
When we build with ftrace enabled its possible that loadcam_entry would have used the stack pointer (even though the code doesn't need it). We call loadcam_entry in __secondary_start before the stack is setup. To ensure that loadcam_entry doesn't use the stack pointer the easiest solution is to just have it in asm code.

2010-05-17powerpc/fsl-booke: Fix InstructionTLBError execute permission checkLi Yang
In CONFIG_PTE_64BIT the PTE format has unique permission bits for user and supervisor execute. However on !CONFIG_PTE_64BIT we overload the supervisor bit to imply user execute with _PAGE_USER set. This allows us to use the same permission check mask for user or supervisor code on !CONFIG_PTE_64BIT. However, on CONFIG_PTE_64BIT we map _PAGE_EXEC to _PAGE_BAP_UX so we need a different permission mask based on the fault coming from a kernel address or user space.

2010-05-17KVM: PPC: Improve split modeAlexander Graf
When in split mode, instruction relocation and data relocation are not equal. So far we implemented this mode by reserving a special pseudo-VSID for the two cases and flushing all PTEs when going into split mode, which is slow. Unfortunately 32bit Linux and Mac OS X use split mode extensively. So to not slow down things too much, I came up with a different idea: Mark the split mode with a bit in the VSID and then treat it like any other segment. This means we can just flush the shadow segment cache, but keep the PTEs intact. I verified that this works with ppc32 Linux and Mac OS X 10.4 guests and does speed them up.

2010-05-17KVM: PPC: Make Performance Counters workAlexander Graf

When an interrupt occurs we don't know yet if we're in guest context or in host context. When in guest context, KVM needs to handle it.

2010-05-17KVM: PPC: Improve indirect svcpu accessorsAlexander Graf
We already have some inline fuctions we use to access vcpu or svcpu structs, depending on whether we're on booke or book3s. Since we just put a few more registers into the svcpu, we also need to make sure the respective callbacks are available and get used. So this patch moves direct use of the now in the svcpu struct fields to inline function calls.
