Currently, we may setup the MFC for isolated mode initilaisation with the purge still active. This means that DMAs required to perform the init do not happen. This change clears the purge status after doing the purge, so that the isolated init can proceed. Signed-off-by:

Currently, spu_handle_mm_fault disregards the 'ret' variable and always returns -EFAULT on error. This change refactos spu_handle_mm_fault a little, to return the ret variable as appropriate. This allows us to combine the error and sucess paths. Also, remove the #if-0-ed IS_VALID_EA() check, it has never been used. Signed-off-by:

At the moment we size the hashtable based on 4kB pages / 2, even on a 64kB kernel. This results in a hashtable that is much larger than it needs to be. Grab the real page size and size the hashtable based on that Note: This only has effect on non hypervisor machines. Signed-off-by:

This patch rewrites consistent dma allocations support to use vmalloc layer to allocate virtual memory space from vmalloc pool and get rid of CONFIG_CONSISTENT_{START,SIZE}. This greatly simplifies the code by effectively removing a custom allocator we had for virtual space. Signed-off-by:

Old OF variants used to create a 'dummy' parent node "multifunc-device" for devices with more than one PCI function. Our code that matches OF nodes to PCI devices dealt with that in one place but not in another, this fixes it. This has the practical effect of fixing interrupt routing of multifunction PCI cards on some older PowerMac machines. Signed-off-by:

Create a new header that becomes a single location for defining PowerPC opcodes used by code that is either generationg instructions at runtime (fixups, debug, etc.), emulating instructions, or just compiling instructions old assemblers don't know about. We currently don't handle the floating point emulation or alignment decode as both are better handled by the specific decode support they already have. Added support for the new dcbzl, dcbal, msgsnd, tlbilx, & wait instructions since older assemblers don't know about them. Signed-off-by:

Impact: clean up, remove duplicate code When ftrace was first ported to PowerPC, there existed a create_function_call that would create the instruction to make a call to a given address. Unfortunately, this call expected to write to the address it was given, and since it used the address to calculate the offset, it could not be faked. ftrace needed a way to create the instruction without actually writing that instruction to the text section. So ftrace had to implement its own code. Now we have create_branch in the code patching library, which does exactly what ftrace needs. This patch replaces ftrace's implementation with the library function. Signed-off-by:

The original port of ftrace to PowerPC kept a lot of the code used by x86. Some of this code was to handle x86's 5 byte instruction. This was handled by using character arrays to manipulate the code. PowerPC has a consistent 4 byte instruction. Using unsigned ints makes the code more efficient as well as more readable. By converting to use unsigned ints to represent instructions, I was able to remove the side effects that were needed for manipulating character strings. i.e. memcpy and memcmp Signed-off-by:

The TOCS used by modules are different than the one used by the core kernel code. The function graph tracer must save and restore the TOC whenever it traces a module call. But this is an added overhead to burden the majority of core kernel code being traced. Benjamin Herrenschmidt suggested in testing the entry of the call to tell if it is a core kernel function or a module. He recommended using the REGION_ID() macro to perform this test. This patch implements Benjamin's idea, and uses a different return_to_handler routine dependent on if the entry is a core kernel function or not. The module version saves the TOC, where as the core kernel version does not. Geoff Lavand tested on PS3. Tested-by:

This is a port of the function graph tracer that was written by Frederic Weisbecker for the x86. This only works for PPC64 at the moment and only for static tracing. PPC32 and dynamic function graph tracing support will come later.

If a USB PCI controller is behind a cardbus bridge, we are trying to restore its configuration registers too early, before the cardbus bridge is operational. To fix this, call pci_restore_state() from usb_hcd_pci_resume() and remove usb_hcd_pci_resume_early() which is no longer necessary (the configuration spaces of USB controllers that are not behind cardbus bridges will be restored by the PCI PM core with interrupts disabled anyway). This patch fixes the regression from 2.6.28 tracked as http://bugzilla.kernel.org/show_bug.cgi?id=12659 [ Side note: the proper long-term fix is probably to just force the unplug event at suspend time instead of doing a plug/unplug at resume time, but this patch is fine regardless - Linus ] Signed-off-by:
