Fix http://bugzilla.kernel.org/show_bug.cgi?id=6128 Finish morphing the "early handoff" version of the EHCI BIOS handshake over to match the previous implementation inside the EHCI driver (except that now we forcibly disable the SMI). The version that had been with the PCI code was surprisingly full of bugs.

When a CPU has no scache, the scache flushing functions currently aren't getting initialized and the NULL pointer is eventually called as a function. Initialize the scache flushing functions as a noop when there's no scache. Initial patch by me and most of the debugging done by Martin Michlmayr.

During testing of SLES10, we encountered a hang in the CFQ io scheduler. Turns out the deferred slice expiry logic is buggy, so remove that for now. We could be left with an idle queue that would never wake up. So kill that logic, always expire immediately. Also fix a potential timer race condition. Patch looks bigger than it is, because it moves a function. Signed-off-by: Jens Axboe <axboe@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Before the merge I updated create_pte_mapping() to work for iSeries, by calling iSeries_hpte_bolt_or_insert. (4c55130b) Later we changed iSeries_hpte_insert to cope with the bolting case, and called that instead from create_pte_mapping() (which was renamed to htab_bolt_mapping) (3c726f8d). Unfortunately that change introduced a subtle bug, where we pass an absolute address to iSeries_hpte_insert() where it expects a physical address. This leads to us calling phys_to_abs() twice on the physical address, which is seriously bogus. This only causes a problem if the absolute address from the first translation can be looked up again in the chunk_map, which depends on the size and layout of memory. I've seen it fail on one box, but not others. The minimal fix is to pass the physical address to iSeries_hpte_insert(). For 2.6.17 we should make phys_to_abs() BUG if we try to double-translate an address. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

Some hotplug driver functions were migrated to the kernel for use by EEH in commit 2bf6a8fa. Previously, the PCI Hotplug module had been changed to use the new OFDT-based PCI probe when appropriate: 5fa80fcd When rpaphp_pci_config_slot() was moved from the rpaphp driver to the new kernel function pcibios_add_pci_devices(), the OFDT-based probe stuff was dropped. This patch restores it. Signed-off-by: John Rose <johnrose@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

In 295f7324 I moved defer_accept from tcp_sock to request_queue and mistakingly reset it at reqsl_queue_alloc, causing calls to setsockopt(TCP_DEFER_ACCEPT ) to be lost after bind, the fix is to remove the zeroing of rskq_defer_accept from reqsl_queue_alloc.

The nfnetlink_log infrastructure changes broke compatiblity of the LOG targets. They currently use whatever log backend was registered first, which means that if ipt_ULOG was loaded first, no messages will be printed to the ring buffer anymore. Restore compatiblity by using the old log functions by default and only use the nf_log backend if the user explicitly said so. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

The only reason post_input exists at all is that it gives us the potential to adjust the checksums incrementally in future which we ought to do. However, after thinking about it for a bit we can adjust the checksums without using this post_input stuff at all. The crucial point is that only the inner-most NAT-T SA needs to be considered when adjusting checksums. What's more, the checksum adjustment comes down to a single u32 due to the linearity of IP checksums. We just happen to have a spare u32 lying around in our skb structure :) When ip_summed is set to CHECKSUM_NONE on input, the value of skb->csum is currently unused. All we have to do is to make that the checksum adjustment and voila, there goes all the post_input and decap structures! I've left in the decap data structures for now since it's intricately woven into the sec_path stuff. We can kill them later too.

A recent change requires cpu_possible_map to be initialized before smp_sched_init() but most MIPS platforms were initializing their processors in the prom_prepare_cpus callback of smp_prepare_cpus. The simple fix of calling prom_prepare_cpus from one of the earlier SMP initialization hooks doesn't work well either since IPIs may require init_IRQ() to have completed, so bit the bullet and split prom_prepare_cpus into two initialization functions, plat_smp_setup which is called early from setup_arch and plat_prepare_cpus called where prom_prepare_cpus used to be called.

The change to kernel/sched.c's init code to use for_each_cpu() requires that the cpu_possible_map be setup much earlier.
