* [POWERPC] Fix unbalanced of_node_{get,put} in efika-setup.cSylvain Munaut2007-02-131-7/+6

* [POWERPC] Use common 52xx of_platform probe code for EFIKASylvain Munaut2007-02-131-46/+18
| | | | | | | | | | | | 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).

* [POWERPC] Restore 'proper' link order in platformSylvain Munaut2007-02-131-1/+1
| | | | | | | | | | | 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: Sylvain Munaut <tnt@246tNt.com> Acked-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Add device tree fixups for the EFIKASylvain Munaut2007-02-131-0/+81
| | | | | | | | | | | 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.

* [POWERPC] mpc5200 device tree bindings refinementGrant Likely2007-02-132-112/+158
| | | | | | | | | | | | | | | | | | 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: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] Fix vDSO page count calculationBenjamin Herrenschmidt2007-02-132-14/+23
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linkstation systems capable of running mainline kernels use u-boot as a bootloader, so, specifying a suitable kernel command is not a problem. Don't guess. Also extend linkstation_defconfig to support the linkstation HS model with a IT8212 IDE controller and kuroboxHD/HD-HLAN linkstation models with a tulip ethernet chip. The latter also require a slightly different .dts file, which is also included with this patch.

So let's remove a whole whack of code for fun and profit. Cribbed compat_sys_sysinfo from x86_64's implementation, since I figured it would be the best tested. This patch incorporates Arnd's suggestion of not using set_fs/get_fs, but instead extracting out the common code from sys_sysinfo.

* | | [PATCH] disable init/initramfs.c: architecturesJean-Paul Saman2007-02-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update all arch/*/kernel/vmlinux.lds.S to not include space for initramfs when CONFIG_BLK_DEV_INITRAMFS is not selected. This saves another 4 kbytes on most platfoms (some reserve PAGE_SIZE for initramfs).

* | | [PATCH] Set CONFIG_ZONE_DMA for arches with GENERIC_ISA_DMAChristoph Lameter2007-02-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Andi pointed out: CONFIG_GENERIC_ISA_DMA only disables the ISA DMA channel management. Other functionality may still expect GFP_DMA to provide memory below 16M. So we need to make sure that CONFIG_ZONE_DMA is set independent of CONFIG_GENERIC_ISA_DMA. Undo the modifications to mm/Kconfig where we made ZONE_DMA dependent on GENERIC_ISA_DMA and set theses explicitly in each arches Kconfig. Reviews must occur for each arch in order to determine if ZONE_DMA can be switched off. It can only be switched off if we know that all devices supported by a platform are capable of performing DMA transfers to all of memory (Some arches already support this: uml, avr32, sh sh64, parisc and IA64/Altix). In order to switch ZONE_DMA off conditionally, one would have to establish a scheme by which one can assure that no drivers are enabled that are only capable of doing I/O to a part of memory, or one needs to provide an alternate means of performing an allocation from a specific range of memory (like provided by alloc_pages_range()) and insure that all drivers use that call. In that case the arches alloc_dma_coherent() may need to be modified to call alloc_pages_range() instead of relying on GFP_DMA.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we do full FP emulation its possible that we need to post a SIGFPE based on the results of the emulation. The previous code ignored this case completely. Additionally, the Soft_emulate_8xx case had two issues. One, we should never generate a SIGFPE since the code only does data movement. Second, we were interpreting the return codes incorrectly, it returns 0 on success, 1 on illop and -EFAULT on a data access error. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
