* [SPARC64]: Move over to GENERIC_HARDIRQS.David S. Miller2006-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | This is the long overdue conversion of sparc64 over to the generic IRQ layer. The kernel image is slightly larger, but the BSS is ~60K smaller due to the reduced size of struct ino_bucket. A lot of IRQ implementation details, including ino_bucket, were moved out of asm-sparc64/irq.h and are now private to arch/sparc64/kernel/irq.c, and most of the code in irq.c totally disappeared. One thing that's different at the moment is IRQ distribution, we do it at enable_irq() time. If the cpu mask is ALL then we round-robin using a global rotating cpu counter, else we pick the first cpu in the mask to support single cpu targetting. This is similar to what powerpc's XICS IRQ support code does. This works fine on my UP SB1000, and the SMP build goes fine and runs on that machine, but lots of testing on different setups is needed.

| | | | | | | | | | | | The mapping is a simple "(cpuid >> 2) == core" for now. Later we'll add more sophisticated code that will walk the sun4v machine description and figure this out from there.

* Make Kprobes depend on modulesLinus Torvalds2006-02-26
| | | | | | | | | Commit 9ec4b1f356b3bad928ae8e2aa9caebfa737d52df made kprobes not compile without module support, so just make that clear in the Kconfig file. Also, since it's marked EXPERIMENTAL, make that dependency explicit too. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [SPARC64] arch/sparc64/Kconfig: fix HUGETLB_PAGE_SIZE_64K dependenciesAdrian Bunk2006-01-11
| | | | | | | | | | | | This patch fixes a typo in the dependencies of HUGETLB_PAGE_SIZE_64K. It might be more logical to rename the HUGETLB_PAGE_SIZE_*K dependencies to HUGETLB_PAGE_SIZE_*KB, but let's fix this bug first. This bug was reported by Jean-Luc Leger <reiga@dspnet.fr.eu.org>.

* [PATCH] Move Kprobes and Oprofile to "Instrumentation Support" menuPrasanna S Panchamukhi2005-11-07
| | | | | | | | | | | | | | | Andrew Morton suggested to move kprobes from kernel hacking menu, since kernel hacking menu is in-appropriate for the Kprobes. This patch moves Kprobes and Oprofile under instrumentation menu.

* [PATCH] Kconfig fix (BLK_DEV_FD dependencies)viro@ZenIV.linux.org.uk2005-09-07
| | | | | | | | | | | | | | | | | 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...

* | [NET]: add a top-level Networking menu to *configSam Ravnborg2005-07-12
|/ | | | | | | | | | | | | | | | | | 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.

* [SPARC64/COMPAT]: Add some compat ioctl for ppdevRaphael Assenat2005-07-04
| | | | | | | | | | | | | | | | | | | | | | | | | | The following patch adds some ioctls to include/linux/compat_ioctl.h to allow using ppdev from the 32 bit user space on sparc64. This patch also adds the PPDEV option in the sparc64 menu, near Parallel printer support in the 'General machine setup' submenu. All those ioctls seem to be compatible, since (correct me if I'm wrong) they dont use the 'long' type. See include/linux/ppdev.h. The application I used to test the new ioctls only used the following: PPEXCL PPCLAIM PPNEGOT PPGETMODES PPRCONTROL PPWCONTROL PPDATADIR PPWDATA PPRDATA But I beleive that the other ioctls will work fine.

* [PATCH] make each arch use mm/KconfigDave Hansen2005-06-23
| | | | | | | | | | | | | | 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.

* [PATCH] missing dependency on sparc64Al Viro2005-04-24
| | | | | | | | | | | | CONFIG_HW_CONSOLE selects vt.c; without the stuff pulled by CONFIG_VT it will not build. Normally we get both in drivers/char/Kconfig and there HW_CONSOLE depends on VT. sparc64 does not pull drivers/char/Kconfig and has that sutff in arch/sparc64/Kconfig instead. However, it forgets to add the same dependency. As the result, turning VT off [which is possible] will end up with broken build. For no good reason...

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
