Add a shutdown member to struct vio_driver. We also need vio_bus_shutdown() which converts from struct device to struct vio_dev and knows how to extract the struct vio_driver. Original patch adjusted for different location of vio.c. Signed-off-by: NMichael Ellerman <michael@ellerman.id.au> Signed-off-by: NStephen Rothwell <sfr@canb.auug.org.au>

Merge arch/ppc64/kernel/vio.c into arch/powerpc/kernel/vio.c, update the Makefiles to make it work, and make ARCH=ppc64 still work. Michael's version put vio.c in arch/powerpc/sysedv but after consolting Paulus, this one puts it in arch/powerpc/kernel.

Previously it claimed 7MB starting at the 9M point and loaded the kernel there. That meant that prom_init put the flattened device tree above 16M. On the 601 that caused the early device tree scan to fail, since only 16MB are mapped with BATs on the 601. Moving this down to 8MB allows prom_init to put the flattened device tree between 15M and 16M, so it works on the 601. Signed-off-by: NPaul Mackerras <paulus@samba.org>

Old powermacs have a number of differences from current machines: - there is no interrupt tree in the device tree, just interrupt or AAPL,interrupt properties - the chosen node in the device tree is called /chosen@0 - the OF claim method doesn't map the memory, so we have to do an explicit map call as well - there is no /chosen/cpu property on SMP machines - the NVRAM isn't structured as a set of partitions. This adapts the merged powermac support code to cope with these issues. Signed-off-by: NPaul Mackerras <paulus@samba.org>

The 601 doesn't have the timebase register; instead it has an RTCL register that counts nanoseconds and wraps at 1000000000, and an RTCU register that counts seconds. This makes the necessary changes for the merged time code to use the RTCL/U registers when the kernel is running on a 601. Signed-off-by: NPaul Mackerras <paulus@samba.org>

This brings in a lot of changes from arch/ppc64/kernel/pmac_*.c to arch/powerpc/platforms/powermac/*.c and makes various minor tweaks elsewhere. On the powermac we now initialize ppc_md by copying the whole pmac_md structure into it, which required some changes in the ordering of initializations of individual fields of it.

This moves smp_space_timers from arch/ppc64/kernel/smp.c to arch/powerpc/kernel/time.c and makes it initialize last_jiffy[] instead of paca[].next_jiffy_update_tb, since last_jiffy[] is now what the time code uses.

When I originally moved exit_itimers into __exit_signal, that was the only place where we could reliably know it was the last thread in the group dying, without races. Since then we've gotten the signal_struct.live counter, and do_exit can reliably do group-wide cleanup work. This patch moves the call to do_exit, where it's made without locks. This avoids the deadlock issues that the old __exit_signal code's comment talks about, and the one that Oleg found recently with process CPU timers.

AMD recently discovered that on some hardware, there is a race condition possible when a C-state change request goes onto the bus at the same time as a P-state change request. Both requests happen, but the southbridge hardware only acknowledges the C-state change. The PowerNow! driver is then stuck in a loop, waiting for the P-state change acknowledgement. The driver eventually times out, but can no longer perform P-state changes. It turns out the solution is to resend the P-state change, which the southbridge will acknowledge normally. Thanks to Johannes Winkelmann for reporting this and testing the fix.

This fixes a stupid typo bug in the iSeries hash table code. When we place a hash PTE in the secondary bucket, instead of setting the SECONDARY flag bit, as we should, we (redundantly) set the VALID flag. This was introduced with the patch abolishing bitfields from the hash table code. Mea culpa, oops. It hasn't been noticed until now because in practice we don't hit the secondary bucket terribly often.

While working on 64K pages, I found this little buglet in our update_mmu_cache() implementation. The code calls __hash_page() passing it an "access" parameter (the type of access that triggers the hash) containing the bits _PAGE_RW and _PAGE_USER of the linux PTE. The latter is useless in this case and the former is wrong. In fact, if we have a writeable PTE and we pass _PAGE_RW to hash_page(), it will set _PAGE_DIRTY (since we track dirty that way, by hash faulting !dirty) which is not what we want. In fact, the correct fix is to always pass 0. That means that only read-only or already dirty read write PTEs will be preloaded. The (hopefully rare) case of a non dirty read write PTE can't be preloaded this way, it will have to fault in hash_page on the actual access.

The merge of syscalls.c & sys_ppc32.c (30286ef6) broke mmap, if the mmap returned a 64 bit address. do_mmap2 was taking the return value from do_mmap_pgoff (an unsigned long), and storing it in an int, before returning it to sys_mmap as an unsigned long. So we were losing the high bits of the address. You would have thought the compiler could catch this for us ...

Merge ppc32 and ppc64 versions of thread_info.h. They were pretty similar already, the chief changes are: - Instead of inline asm to implement current_thread_info(), which needs to be different for ppc32 and ppc64, we use C with an asm("r1") register variable. gcc turns it into the same asm as we used to have for both platforms. - We replace ppc32's 'local_flags' with the ppc64 'syscall_noerror' field. The noerror flag was in fact the only thing in the local_flags field anyway, so the ppc64 approach is simpler, and means we only need a load-immediate/store instead of load/mask/store when clearing the flag. - In readiness for 64k pages, when THREAD_SIZE will be less than a page, ppc64 used kmalloc() rather than get_free_pages() to allocate the kernel stack. With this patch we do the same for ppc32, since there's no strong reason not to. - For ppc64, we no longer export THREAD_SHIFT and THREAD_SIZE via asm-offsets, thread_info.h can now be safely included in asm, as on ppc32. Built and booted on G4 Powerbook (ARCH=ppc and ARCH=powerpc) and Power5 (ARCH=ppc64 and ARCH=powerpc).
