2006-12-08[PATCH] LOG2: Implement a general integer log2 facility in the kernelDavid Howells
This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. 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.

2006-12-06sh: sh775x/titan fixes for irq header changes.Jamie Lenehan
The following moves the creation of IPR interupts into setup-7750.c and updates a few other things to make it all work after the "Drop CPU subtype IRQ headers" commit. It boots and runs fine on my titan board. - adds an ipr_idx to the ipr_data and uses a function in the subtype code to calculate the address of the IPR registers - adds a function to enable individual interrupt mode for externals in the subtype code and calls that from the titan board code instead of doing it directly. - I changed the shift in the ipr_data to be the actual # of bits to shift, instead of the numnber / 4 - made it easier to match with the manual.

2006-12-06sh: generic push-switch framework.Paul Mundt
This adds support for a generic push switch framework. Adaptable for various switches, including GPIO switches and the push switches commonly found on Renesas debug boards. This allows switch states to be trivially reported through sysfs. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: Explicit endian selection support.Paul Mundt
Previously big endian was simply assumed if little endian was not set, which led to some cflags ordering issues. There's not much point to not having a big endian option, so shove one in a choice and wire it up in the Makefile. This lets us clean up some of the cflags ordering while we're at it.

2006-10-06sh: First step at generic timeofday support.Paul Mundt
At the moment we wrap GENERIC_TIME around our existing timer API. As boards start providing their own clocksources, they're able to select GENERIC_TIME accordingly and optimize out most of the timer API. Once the current timers have been reworked as proper clocksource drivers, the rest of the place holders for the timer API can go away and we can flip on GENERIC_TIME unconditionally.

2006-04-11[PATCH] Configurable NODES_SHIFTYasunori Goto
Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.

Currently the CPU subtype options are cluttering up arch/sh/Kconfig somewhat. Given that, this moves all of that in to its own arch/sh/mm/Kconfig. Things like cache configuration are also moved to this new location. This also adds support for strict CPU tuning on newer cores, which requires the addition of as-option.

2005-11-07[PATCH] sh: Drop hp690 discontig supportPaul Mundt
There was only one board using this (hp690 specifically), and it just so happens that it's only physically discontiguous at the "normal" P1 offset. If we bump up the P1 offset, it's possible to hit a shadowed region of memory where we suddenly become magically contiguous. As people have been using this shadowed region workaround for quite some time (and without any adverse effects), it's time to drop the left over discontig bits that no longer have any practical use (it was always very much hp690-centric to begin with).

2005-09-07[PATCH] Kconfig fix (BLK_DEV_FD dependencies)viro@ZenIV.linux.org.uk
Sanitized and fixed floppy dependencies: split the messy dependencies for BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making BLK_DEV_FD depend on that one and taking declarations of ARCH_MAY_HAVE_PC_FDC to arch/*/Kconfig. While we are at it, fixed several obvious cases when BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h are *not* going to have floppy.c compile, let alone work). If you can come up with better name for that ("this architecture might have working PC-compatible floppy disk controller"), you are more than welcome - just s/ARCH_MAY_HAVE_PC_FDC/your_prefered_name/g in the patch below...

2005-07-11[NET]: add a top-level Networking menu to *configSam Ravnborg
Create a new top-level menu named "Networking" thus moving net related options and protocol selection way from the drivers menu and up on the top-level where they belong. To implement this all architectures has to source "net/Kconfig" before drivers/*/Kconfig in their Kconfig file. This change has been implemented for all architectures. Device drivers for ordinary NIC's are still to be found in the Device Drivers section, but Bluetooth, IrDA and ax25 are located with their corresponding menu entries under the new networking menu item.

2005-06-23[PATCH] make each arch use mm/KconfigDave Hansen
For all architectures, this just means that you'll see a "Memory Model" choice in your architecture menu. For those that implement DISCONTIGMEM, you may eventually want to make your ARCH_DISCONTIGMEM_ENABLE a "def_bool y" and make your users select DISCONTIGMEM right out of the new choice menu. The only disadvantage might be if you have some specific things that you need in your help option to explain something about DISCONTIGMEM.

2005-05-04[PATCH] ISA DMA Kconfig fixes - part 1Al Viro
A bunch of drivers use ISA DMA helpers or their equivalents for platforms that have ISA with different DMA controller (a lot of ARM boxen). Currently there is no way to put such dependency in Kconfig - CONFIG_ISA is not it (e.g. it is not set on platforms that have no ISA slots, but have on-board devices that pretend to be ISA ones). New symbol added - ISA_DMA_API. Set when we have functional enable_dma()/set_dma_mode()/etc. set of helpers. Next patches in the series will add missing dependencies for drivers that need them. I'm very carefully staying the hell out of the recurring flamefest on what exactly CONFIG_ISA would mean in ideal world - added symbol has a well-defined meaning and for now I really want to treat it as completely independent from the mess around CONFIG_ISA.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
