This patch removes the need for struct page for SPE local store and registers from spufs. It also makes the locking much more obvious and no longer relying on the truncate logic black magic for protecting against races between unmap_mapping_range() and new pages faulted in. It does so by switching to a nopfn() handler and using the new vm_insert_pfn() to setup the PTEs itself while holding a lock on the SPE. The nice thing is that this patch actually removes a lot more code than it adds :-) Signed-off-by:

The efika platform used three files efika-pci.c efika-setup.c and a 2 line efika.h to link the two. The total of code in those is really not much and therefore, I think they're better merged in a single file. There is absolutely _no_code_change_ at all, just merged the files. Signed-off-by:

Now that the device tree has the good properties, we can remove all the efika_init code by a single call to common code. While we're modifying that file, a few whitespaces/alignement/typo fixes are made (nothing significant). Signed-off-by:

The 52xx was put before CHRP to allow EFIKA to be recognized properly. Now the efika tree is fixed up in prom_init so no need for this ugly hack. So we restore the 'normal' order. Signed-off-by:

We make the efika device tree compliant with the defined bindings (at least compliant enough). This is mostly done by mangling the device_type and compatible properties, but also adding some missing bits. Signed-off-by:

Much needed refinement of mpc5200 device tree binding specifications. Short list: - drop mpc52xx designator; only two supported chips exist, 5200 and 5200b. It's premature to refer to them as '52xx'. - Specify optional 'model' and 'revision' properties in the soc5200 node - Specify reqiured 'cell-index' property to identify between multiple SOC devices of the same type. (Useful for arbitrating shared register access) - Specify optional 'port-number' property for adjusting the logical serial port assignments. - Specify optional 'has-wdt' property for gpt0 node. - Add system-frequency property to soc5200 node Signed-off-by:

This patch adds support for the AMCC Taishan PPC440GX evaluation board. This is still an arch/ppc port. I'm aware that the move of 4xx to arch/powerpc is making good progress right now. So this patch is mainly intended to make the Taishan support available for the community right now. Signed-off-by:

The recent vDSO consolidation patches broke powerpc due to a mistake in the definition of MAXPAGES constants. This fixes it by moving to a dynamically allocated array of pages instead as I don't like much hard coded size limits. Also move the vdso initialisation to an initcall since it doesn't really need to be done -that- early. Applogies for not catching the breakage earlier, Roland _did_ CC me on his patches a while ago, I got busy with other things and forgot to test them. Signed-off-by:

During ppc64+ppc merge virtual DMA code for floppy driver was not ported. This patch restores virtual DMA support for floppy in new powerpc target. It is necessary at least on Pegasos and AmigaOne machines for the floppy drive to function. ISA DMA controller works incorrectly there due to its addressing limitations. Virtual DMA mode is activated by floppy=nodma option passed to the kernel (or module). There's no automatic switch like on i386. Signed-off-by:

This reverts some bogosity from the dynamic command-line changes made on sparc32 and sparc64. Drivers such as drivers/sbus/char/openprom.c reference saved_command_line, and can be modular. The boot_command_line is __initdata, yet the dynamic command-line changes add modular exports of that symbol, obviously wrong. Signed-off-by:David S. Miller <davem@davemloft.net>

NF_CT_STAT_INC assumes rcu_read_lock in nf_hook_slow disables preemption as well, making it legal to use __get_cpu_var without disabling preemption manually. The assumption is not correct anymore with preemptable RCU, additionally we need to protect against softirqs when not holding nf_conntrack_lock. Add NF_CT_STAT_INC_ATOMIC macro, which disables local softirqs, and use where necessary. Signed-off-by:
