2005-11-06[PATCH] ppc64: support 64k pagesBenjamin Herrenschmidt
Adds a new CONFIG_PPC_64K_PAGES which, when enabled, changes the kernel base page size to 64K. The resulting kernel still boots on any hardware. On current machines with 4K pages support only, the kernel will maintain 16 "subpages" for each 64K page transparently. Note that while real 64K capable HW has been tested, the current patch will not enable it yet as such hardware is not released yet, and I'm still verifying with the firmware architects the proper to get the information from the newer hypervisors.

2005-11-06[ARM] Fix /proc/cpuinfo format for ARM SMPRussell King
glibc expects to count lines beginning with "processor" to determine the number of processors, not lines beginning with "Processor". So, give glibc the format it expects. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-11-06[ARM] Don't call dump_cpu_info unless we're bootingRussell King
We don't want to call dump_cpu_info() from cpu_init() after boot since it produces a lot of unnecessary noise - since cpu_init() gets called on resume and hotplug cpu insertion events. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-11-06[ARM] 3113/1: PXA: Allow machines to override (and also reuse) pxa pm functionsRichard Purdie
Patch from Richard Purdie Update the PXA pm.c file to allow machines (such as the Sharp Zaurus) to override the standard pm functions but reuse/wrap them where needed. The init call is made slightly earlier to give machine code an init level to override them in removing any race.

2005-11-06[ARM] 3115/1: small optimizations to exception vector entry codeNicolas Pitre

2005-11-06[ARM] 3089/1: ixp4xx AHB/PCI endianness fixAlessandro Zummo
Patch from Alessandro Zummo This patch fixes AHB/PCI endianness problems when the processor is in little-endian mode. The patch configures the CSR register closely following the directives in [1], paragraph 4.1, page 19. According to the considerations in [1], page 11, while the AHB bus supports both endian modes, on the IXP4XX it always uses big-endian. The PCI bus is connected to the South AHB. A wrong setting in the CSR register will thus cause a malfunctional PCI bus. A schematic diagram of the bus interconnections on the IXP4XX can be found in [1], page 18. The patch has been verified to work on the NSLU2 in both LE and BE modes. The author is Peter Korsgaard.

2005-11-05[PATCH] reset tss->io_bitmap_owner in sys_ioperm()Bart Oldeman
my patch "x86: initialise tss->io_bitmap_owner to something" (commit ID d5cd4aadd3d220afac8e3e6d922e333592551f7d) introduced a problem with a program (DOSEMU) that called ioperm after already doing some port i/o. The problem is that a process switch return causes tss->io_bitmap_base to be set to IO_BITMAP_OFFSET so that the fault (that *really* sets the io bitmap) never triggers. This fixes that regression.

2005-11-05powerpc: Fix vmlinux.lds.S for 32-bitPaul Mackerras
We can't currently use asm-ppc/page.h in vmlinux.lds.S, so until we have a merged page.h, define PAGE_SIZE and KERNELBASE locally. Also gets rid of some dynamic executable cruft that we had for 32-bit. With -Ttext=$(KERNELBASE) this didn't cause any problem, but when we changed to putting . = KERNELBASE in the vmlinux.lds.S this cruft caused the text to get linked at 0xa0 instead of 0xc0000000. Oops. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-05powerpc: Merge smp.c and smp.hPaul Mackerras

2005-11-04[ARM] 3097/1: change library link orderingNicolas Pitre
Patch from Nicolas Pitre We have an optimized sha1 routine (arch/arm/lib/sha1.S) meant to override the generic one in lib/sha1.c. Unfortunately lib/lib.a is listed _before_ arch/arm/lib/lib.a in the link argument list and therefore the architecture specific lib functions are not picked up before the generic versions. This patch is a quick fix to change that ordering for ARM. Here's what the kbuild maintainer had to say about it (was also CC'd on lkml): On Wed, 2 Nov 2005, Sam Ravnborg wrote: > This looks like an obvious way to achive correct ordering. > We could change it so arch defines always took precedence but > the above is so simple that it is not worth the effort.

Patch from Todd Poynor Add platform devices for flash to Lubbock and Mainstone board files. Once in place, the two existing mtd map drivers for the boards will be converted to use a single pxa2xx map driver in the linux-mtd tree.

2005-11-04[ARM] 3086/1: ixp2xxx error irq handlingDave Jiang
Patch from Dave Jiang This provides support for IXP2xxx error interrupt handling. Previously there was a patch to remove this (although the original stuff was broken). Well, now the error bits are needed again. These are used extensively by the micro-engine drivers according to Deepak and also we will need it for the new EDAC code that Alan Cox is trying to push into the main kernel. Re-submit of 3072/1, generated against git tree pulled today. AFAICT, this git tree pulled in all the ARM changes that's in arm.diff. Please let me know if there are additional changes. Thx!

2005-11-03powerpc: Cleanup vpa codeMichael Ellerman
register_vpa() doesn't actually do a VPA register call it just uses the flags you pass it, so rename it to vpa_call() to be clearer. We can then define register_vpa() and unregister_vpa() which are both simple wrappers around vpa_call(). (we'll need unregister_vpa() for kexec soon) We can then cleanup vpa_init(), and because vpa_init() is only called from platforms/pseries we remove the definition in asm-ppc64/smp.h.

2005-11-03powerpc: Set entry point and text address in linker scriptMichael Ellerman
Currently we set the kernel entry point and the address of the text section in the Makefile, using CONFIG_KERNEL_START. But we've already got <asm/page.h> in the linker script, so we can just use KERNELBASE directly. That means if we ever change KERNELBASE there's one less place to change it. And we can set the entry point with ENTRY(). There are zero differences from "readelf -a vmlinux" with or without this patch. Signed-off-by: Michael Ellerman <michael@ellerman.id.au>
