* [POWERPC] 8xx: generic 8xx code arch/powerpc portVitaly Bordug2007-02-072-443/+0
| | | | | | | | | | | | | | | | | Including support for non-coherent cache, some mm-related things + relevant field in Kconfig and Makefiles. Also included rheap.o compilation if 8xx is defined. Non-coherent mapping were refined and renamed according to Cristoph Hellwig. Orphaned functions were cleaned up. [Also removed arch/ppc/kernel/dma-mapping.c, because otherwise compiling with ARCH=ppc for a non DMA-cache-coherent platform ends up with two copies of __dma_alloc_coherent etc. -- paulus.] Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | * [POWERPC] Fix mmap of PCI resource with hack for XBenjamin Herrenschmidt2006-12-081-9/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The powerpc version of pci_resource_to_user() and associated hooks used by /proc/bus/pci and /sys/bus/pci mmap have been broken for some time on machines that don't have a 1:1 mapping of devices (basically on non-PowerMacs) and have PCI devices above 32 bits. This attempts to fix it as well as possible. The rule is supposed to be that pci_resource_to_user() always converts the resources back into a BAR values since that's what the /proc interface was supposed to deal with. However, for X to work on platforms where PCI MMIO is not mapped 1:1, it became a habit of platforms like powerpc to pass "fixed up" values there since X expects to be able to use values from /proc/bus/pci/devices as offsets to mmap of /dev/mem... So we keep that contraption here, causing also /sys/*/resource to expose fully absolute MMIO addresses instead of BAR values, which is ugly, but should still work as long as those are only used to calculate alignment within a page. X is still broken when built 32 bits on machines where PCI MMIO can be above 32-bit space unfortunately.

| * | [PATCH] LOG2: Implement a general integer log2 facility in the kernelDavid Howells2006-12-081-0/+8

They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds code to look at the properties firmware puts in the device tree to determine what compatibility mode the partition is in on POWER6 machines, and set the ELF aux vector AT_HWCAP and AT_PLATFORM entries appropriately. Specifically, we look at the cpu-version property in the cpu node(s). If that contains a "logical" PVR value (of the form 0x0f00000x), we call identify_cpu again with this PVR value. A value of 0x0f000001 indicates the partition is in POWER5+ compatibility mode, and a value of 0x0f000002 indicates "POWER6 architected" mode, with various extensions disabled. We also look for various other properties: ibm,dfp, ibm,purr and ibm,spurr. Signed-off-by: Paul Mackerras <paulus@samba.org>

The main issue was that the construct: .long label (or .llong on 64 bits) will not work in the case of a shared library like the vdso. It will generate an empty placeholder in the fixup table along with a reloc, which is not something we can deal with in the vdso. The idea here (thanks Alan Modra !) is to instead use something like: 1: .long label - 1b That is, the feature fixup tables no longer contain addresses of bits of code to patch, but offsets of such code from the fixup table entry itself. That is properly resolved by ld when building the .so's. I've modified the fixup mecanism generically to use that method for the rest of the kernel as well. Another trick is that the 32 bits vDSO included in the 64 bits kernel need to have a table in the 64 bits format. However, gas does not support 32 bits code with a statement of the form: .llong label - 1b (Or even just .llong label) That is, it cannot emit the right fixup/relocation for the linker to use to assign a 32 bits address to an .llong field. Thus, in the specific case of the 32 bits vdso built as part of the 64 bits kernel, we are using a modified macro that generates: .long 0xffffffff .llong label - 1b Note that is assumes that the value is negative which is enforced by the .lds (those offsets are always negative as the .text is always before the fixup table and gas doesn't support emiting the reloc the other way around).

* [PATCH] mm: use symbolic names instead of indices for zone initialisationMel Gorman2006-10-111-3/+4
| | | | | | | | | | | | | | | | | | | | | | | Arch-independent zone-sizing is using indices instead of symbolic names to offset within an array related to zones (max_zone_pfns). The unintended impact is that ZONE_DMA and ZONE_NORMAL is initialised on powerpc instead of ZONE_DMA and ZONE_HIGHMEM when CONFIG_HIGHMEM is set. As a result, the the machine fails to boot but will boot with CONFIG_HIGHMEM turned off. The following patch properly initialises the max_zone_pfns[] array and uses symbolic names instead of indices in each architecture using arch-independent zone-sizing. Two users have successfully booted their powerpcs with it (one an ibook G4). It has also been boot tested on x86, x86_64, ppc64 and ia64. Please merge for 2.6.19-rc2.

| | | | | | | | | The patch below corrects multiple occurances of "the the" typos across several files, both in source comments and KConfig files. There is no actual code changed, only text. Note this only affects the /arch directory, and I believe I could find many more elsewhere. :) Signed-off-by: Adrian Bunk <bunk@stusta.de>

The implementation uses code from the _syscall3 macros provided in the unistd.h header file. I don't have cross-compilers for any of these architectures, so the patch is untested with the exception of i386. Most architectures can probably implement this in a nicer way in assembly or by combining it with the sys_execve implementation itself, but this should do it for now.

* | | [PATCH] const struct tty_operationsJeff Dike2006-10-021-1/+1

One of these structures was a struct tty_operations. In order to const it in UML without introducing compiler complaints, the declaration of tty_set_operations needs to be changed, and then all of its callers need to be fixed. This patch declares all struct tty_operations in the tree as const. In all cases, they are static and used only as input to tty_set_operations. As an extra check, I ran an i386 allyesconfig build which produced no extra warnings. 53 drivers are affected. I checked the history of a bunch of them, and in most cases, there have been only a handful of maintenance changes in the last six months. serial_core.c was the busiest one that I looked at.

So we can kill wall_jiffies completely. This is just a cleanup and logically should not change any real behavior except for one thing: RTC updating code in (old) ppc and xtensa use a condition "jiffies - wall_jiffies == 1". This condition is never met so I suppose it is just a bug. I just remove that condition only instead of kill the whole "if" block.
