| * | [POWERPC] Remove flush_dcache_all exportMatt Porter2006-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removes the flush_dcache_all export for non coherent platforms. We removed the last in-kernel user of this years ago in arch/ppc so it no longer serves a purpose. Plus, it breaks the build at the moment.

* | | [PATCH] ppc32: fix last_jiffy time comparisonPaul Mackerras2006-08-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a hang on ppc32. The problem was that I was comparing a 32-bit quantity with a 64-bit quantity, and consequently time wasn't advancing. This makes us use a 64-bit quantity on all platforms, which ends up simplifying the code since we can now get rid of the tb_last_stamp variable (which actually fixes another bug that Ben H and I noticed while going carefully through the code). This works fine on my G4 tibook. Let me know how it goes on your machines.

On module load, the placement may cause the xpc_remote_copy_buffer to span two physical pages. DMA transfers are done to the start virtual address translated to physical. This patch changes the buffer from a statically allocated buffer to a kmalloc'd buffer. Dean Nelson reviewed this before posting. I have tested it in the configuration that was showing the memory corruption and verified it works. I also added a BUG_ON statement to help catch this if a similar situation is encountered.

Further, the stack pointer retrieval for the fallback should be as restrictive as possible (in order to avoid having the legacy stack tracer try to access invalid memory). The patch tightens that, but this could certainly be further improved. Also making the call_trace command line option now conditional upon CONFIG_STACK_UNWIND (as it's meaningless otherwise).

However it also breaks the Apple x86 Macs, which can't supply this properly, but need a working MCFG. With this patch they wouldn't use the MCFG and not work. After some discussion I think it's best to remove the heuristic again. It also failed on some other boxes (although it didn't cause much problems there because old style port access for PCI config space still works as fallback), but the preproduction SDVs can just use pci=nommcfg. Supporting production machines properly is more important. Edgar Hucek did all the debugging work.

It is absolutely necessary to update all sub-ptes of a largepage mapping on a fault. Adding special handling for this would add considerably complexity to tlb_batch_add(). So let's just side-step the issue and forcefully dirty any writable PTEs created by io_remap_pfn_range(). The only other real option would be to disable to large PTE code of io_remap_pfn_range() and we really don't want to do that.

The patch changes the PCI init code to have PCBIOS as last fallback, yet the PCBIOS code still has to run first to set pcibios_last_bus to the value reported by the BIOS. this is needed in case legacy PCI probing (arch/i386/pci/legacy.c) is used to detect peer busses. using direct access if available fixes the cardbus problems.

Alright, this one is only triggered when slab debugging is enabled. The slabs are assumed to be aligned on a HUGEPTE_TABLE_SIZE boundary. The free path makes use of this assumption and uses the lowest nibble to pass around an index into an array of kmem_cache pointers. With slab debugging turned on, the slab is still aligned, but the "working" object pointer is not. This would break the assumption above that a full nibble is available for the PGF_CACHENUM_MASK. The following patch reduces PGF_CACHENUM_MASK to cover only the two least significant bits, which is enough to cover the current number of 4 pgtable cache types. Then use this constant to mask out the appropriate part of the huge pte pointer.

| * | | | [POWERPC] Correct masks used in emulating some instructionsPaul Mackerras2006-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we get an illegal instruction exception, we check to see whether the instruction is one that we emulate for the user program. Some of the masks we use in checking whether the offending instruction is one we care about didn't have the top bit set, which is the MSB of the major opcode. Thus some undefined opcodes could get emulated as other (defined but unimplemented) instructions. This corrects the masks. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bootx_init.c trampoline didn't properly add the ramdisk to the "reserve map" (list of reserved areas of memory), thus causing all sorts of failures when using BootX with an initrd. Also fixes a possible problem if the ramdisk is located before the device-tree passed by BootX.

| * | | | [POWERPC] Fix gettimeofday inaccuraciesNathan Lynch2006-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two problems in the powerpc gettimeofday code which can cause incorrect results to be returned. The first is that there is a race between do_gettimeofday and the timer interrupt: 1. do_gettimeofday does get_tb() 2. decrementer exception on boot cpu which runs timer_recalc_offset, which also samples the timebase and updates the do_gtod structure with a greater timebase value. 3. do_gettimeofday calls __do_gettimeofday, which leads to the negative result from tb_val - temp_varp->tb_orig_stamp. The second is caused by taking the boot cpu offline, which can cause the value of tb_last_jiffy to be increased past the currently available timebase, causing the same underflow as above.
