2006-01-15powerpc/32: Restore previous version of 32-bit PCI codePaul Mackerras
When I removed the powermac support from arch/ppc/kernel/pci.c, I overlooked the fact that that file is used in 32-bit ARCH=powerpc builds. To prevent problems in future, restore the original version of that file as arch/powerpc/kernel/pci_32.c, and use that. Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-15[PATCH] ppc: Remove powermac support from ARCH=ppcPaul Mackerras
This makes it possible to build kernels for PReP and/or CHRP with ARCH=ppc by removing the (non-building) powermac support. It's now also possible to select PReP and CHRP independently. Powermac users should now build with ARCH=powerpc instead of ARCH=ppc. (This does mean that it is no longer possible to build a 32-bit kernel for a G5.)

2006-01-14[PATCH] enable unit-at-a-time optimisations for gcc4Ingo Molnar
Allow gcc4 compilers to optimize unit-at-a-time. This flag enables gcc to "see" the entire C file before making optimisation decisions such as inline, which results in gcc making better decisions. One of the immediate effects of this is that static functions that are used only once now get inlined. gcc 3.4 has this flag as well, however gcc 3.x have a problem with inlining and stacks and as a result, enabling this flag there would cause excessive and unacceptable stack use. This problem is fixed in the gcc 4.x series. The x86-64 architecture already enables this feature so it's well tested already.

2006-01-14[PATCH] gx1fb: (try to) play nicer with various BIOSesDavid Vrabel
Seems that the CS5530A chip used in Geode GX1 systems has some crazy feature that causes SMI traps when accessing the PCI configuration space of the video device. Various GX1 BIOSes seem to use this 'feature' to hide the real BARs of the device. This patch disables these traps (in an early PCI fixup) so that Linux sees the real, physical BARs and not the virtual ones provided by the BIOS. This should allow the GX1 framebuffer driver to work on more systems that have different BIOSes as the driver no longer guesses at what the virtual BARs mean. I'm not entirely sure it the correct solution as I can neither test regular VGA console nor the X's 'cyrix' video driver so there might be some breakage there -- probably best to get some more testers before applying it.

2006-01-14[PATCH] s390: show_task oopsHeiko Carstens
The show_task function walks the kernel stack backchain of processes assuming that the processes are not running. Since this assumption is not correct walking the backchain can lead to an addressing exception and therefore to a kernel hang. So prevent the kernel hang (you still get incorrect results) verity that all read accesses are within the bounds of the kernel stack before performing them.

2006-01-14[ARM] 3105/4: ARM EABI: new syscall entry conventionNicolas Pitre
Patch from Nicolas Pitre For a while we wanted to change the way syscalls were called on ARM. Instead of encoding the syscall number in the swi instruction which requires reading back the instruction from memory to extract that number and polluting the data cache, it was decided that simply storing the syscall number into r7 would be more efficient. Since this represents an ABI change then making that change at the same time as EABI support is the right thing to do. It is now expected that EABI user space binaries put the syscall number into r7 and use "swi 0" to call the kernel. Syscall register argument are also expected to have "EABI arrangement" i.e. 64-bit arguments should be put in a pair of registers from an even register number. Example with long ftruncate64(unsigned int fd, loff_t length): legacy ABI: - put fd into r0 - put length into r1-r2 - use "swi #(0x900000 + 194)" to call the kernel new ARM EABI: - put fd into r0 - put length into r2-r3 (skipping over r1) - put 194 into r7 - use "swi 0" to call the kernel Note that it is important to use 0 for the swi argument as backward compatibility with legacy ABI user space relies on this. The syscall macros in asm-arm/unistd.h were also updated to support both ABIs and implement the right call method automatically.

2006-01-14[ARM] 3102/1: ARM EABI: stack pointer must be 64-bit aligned after a CPU ↵Nicolas Pitre
exception Patch from Nicolas Pitre The ARM EABI says that the stack pointer has to be 64-bit aligned for reasons already mentioned in patch #3101 when calling C functions. We therefore must verify and adjust sp accordingly when taking an exception from kernel mode since sp might not necessarily be 64-bit aligned if the exception occurs in the middle of a kernel function. If the exception occurs while in user mode then no sp fixup is needed as long as sizeof(struct pt_regs) as well as any additional syscall data stack space remain multiples of 8.

2006-01-14[PATCH] powerpc: Recognize /chaos bridge on old pmacs as PCIPaul Mackerras
The first generation of PCI powermacs had a host bridge called /chaos which was for all intents and purposes a PCI host bridge, but has a device_type of "vci" in the device tree (presumably it's not really PCI at the hardware level or something). The OF parsing stuff in arch/powerpc/kernel/prom_parse.c currently doesn't recognize it as a PCI bridge, which means that controlfb.c can't get its device addresses. This makes prom_parse.c recognize a device_type of "vci" as indicating a PCI host bridge. With this, controlfb works again.

2006-01-14powerpc: Avoid unaligned loads and stores in boot memcpy codePaul Mackerras
The 601 processor will generate an alignment exception for accesses which cross a page boundary. In the boot wrapper code, OF is still handling all exceptions, and it doesn't have an alignment exception handler that emulates the instruction and continues. This changes the memcpy and memmove routines in the boot wrapper to avoid doing unaligned accesses. If the source and destination are misaligned with respect to each other, we just copy one byte at a time. Signed-off-by: Paul Mackerras <paulus@samba.org>
