2007-02-07[POWERPC] Add "is_power_of_2" checking to log2.h.Robert P. J. Day
Add the inline function "is_power_of_2()" to log2.h, where the value zero is *not* considered to be a power of two. Signed-off-by: Robert P. J. Day <rpjday@mindspring.com> Acked-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-02-07[POWERPC] MPIC: support more than 256 sourcesOlof Johansson
Allow more than the default 256 MPIC sources. Allocates a new flag (MPIC_LARGE_VECTORS) to be used by platform code when instantiating the mpic. I picked 11 bits worth right now since it would cover the number of sources on any hardware I have seen. It can always be increased later if needed.

2007-02-07[POWERPC] Introduce _SYSDEV_ATTROlof Johansson

2007-02-07[POWERPC] Add PMC type to cputableOlof Johansson
Add cputable entries for which type of PMC implementation the processor has. I've only filled in the current 64-bit processors, the unfilled default value will have same behaviour as before so it can be done over time as needed. Also tidy up the dummy_perf implementation a bit, aggregating it into one function with ifdefs instead of several.

2007-02-07[POWERPC] Oprofile cleanupOlof Johansson
Clean up the ctr_read/write a bit. It's currently defined in the include but only used in one C file each. The only exception is the classic version, so keep that in the include and define in the C file as appropriate.

2007-02-07[POWERPC] Fix array indexing error in rheap grow()Timur Tabi
The grow() function in the rheap library allocates a larger array of blocks, copies the contents of the old blocks array to the newly allocated array and fixes the list_head pointers after the copy. At the end, the new blocks must be enqueued to the empty_list of the rh_info_t structure. This patch fixes a bug where the code was indexing past the end of the array when enqueueing blocks. The UCC ethernet driver, which uses the rheap allocator, experiences kernel panics because of this bug.

2007-02-07[POWERPC] pSeries: EEH improperly enabled for some Power4 systemsLinas Vepstas
It appears that EEH is improperly enabled for some Power4 systems. On these systems, the ibm,set-eeh-option returns a value of success even when EEH is not supported on the given node. Thus, an explicit check for support is required. During boot, on power4, without this patch, one sees messages similar to: EEH: event on unsupported device, rc=0 dn=/pci@400000000110/IBM,sp@1 EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2 EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2,2 etc. The patch makes these go away. Without this patch, EEH recovery does seem to work correctly for at least some devices (I tested ethernet e1000), but fails to recover others (the Emulex LightPulse LPFC, most notably). Off the top of my head, I don't remember why some devices are affected, but not others. The PAPR indicates that the correct way to test for EEH is as done in this patch; its not clear to me if this was in the PAPR all along, or recently added; if it was there all along, its not clear to me why this hadn't been fixed long ago. I suspect only certain firmware levels are affected. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

Non-coherent mapping were refined and renamed according to Cristoph Hellwig. Orphaned functions were cleaned up.

2007-01-26[POWERPC] 83xx: Return a point to the struct ipic from ipic_init()Kumar Gala
It's useful to have access to struct ipic handle that just got created in ipic_init(). For example, if we want to setup an external IRQ with out a device node we need access ipic->irqhost to create the virtual to HW IRQ mapping and to set the IRQ sense.

2007-01-26[POWERPC] 83xx: Don't call ioremap in the reset functionKumar Gala
It's possibly that we get an reset requestion when interrupts are disabled. (For example an oops in an interrupt handler). Therefor, we can't call ioremap in the reset function. Moving the ioremap of the registers we need access to an arch_initcall helps the problem. However we still have a window between boot and the arch_initcall in which the register pointer will not be setup and thus we spin if the reset function is called. If one needs to ensure even this case is covered, look at use of the watchdog provided on 83xx to reset the processor. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
