* [PATCH] NTP: ntp-helper functionsjohn stultz2005-09-07
| | | | | | | | | | | | | | | | This patch cleans up a commonly repeated set of changes to the NTP state variables by adding two helper inline functions: ntp_clear(): Clears the ntp state variables ntp_synced(): Returns 1 if the system is synced with a time server. This was compile tested for alpha, arm, i386, x86-64, ppc64, s390, sparc, sparc64.

* [PATCH] convert signal handling of NODEFER to act like other Unix boxes.Steven Rostedt2005-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been reported that the way Linux handles NODEFER for signals is not consistent with the way other Unix boxes handle it. I've written a program to test the behavior of how this flag affects signals and had several reports from people who ran this on various Unix boxes, confirming that Linux seems to be unique on the way this is handled. The way NODEFER affects signals on other Unix boxes is as follows: 1) If NODEFER is set, other signals in sa_mask are still blocked. 2) If NODEFER is set and the signal is in sa_mask, then the signal is still blocked. (Note: this is the behavior of all tested but Linux _and_ NetBSD 2.0 *). The way NODEFER affects signals on Linux: 1) If NODEFER is set, other signals are _not_ blocked regardless of sa_mask (Even NetBSD doesn't do this). 2) If NODEFER is set and the signal is in sa_mask, then the signal being handled is not blocked. The patch converts signal handling in all current Linux architectures to the way most Unix boxes work. Unix boxes that were tested: DU4, AIX 5.2, Irix 6.5, NetBSD 2.0, SFU 3.5 on WinXP, AIX 5.3, Mac OSX, and of course Linux 2.6.13-rcX. * NetBSD was the only other Unix to behave like Linux on point #2. The main concern was brought up by point #1 which even NetBSD isn't like Linux. So with this patch, we leave NetBSD as the lonely one that behaves differently here with #2.

* [PATCH] m32r: Fix local-timer event handlingHirokazu Takata2005-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a scheduling problem of the m32r SMP kernel; A process rarely stopped and gave no responding but the other process have been handled by the other CPU still lives, then if we did something in the other terminal or something like that, the stopped process came back to life and continued its operation... (ex. LMbench: lat_sig) In the m32r SMP kernel, a local-timer event is delivered by using an IPI(inter processor interrupts); LOCAL_TIMER_IPI. And a function smp_send_timer() is prepared to send the LOCAL_TIMER_IPI from the current CPU to the other CPUs. The funtion smp_send_timer() was placed and used in do_IRQ() in former times (before 2.6.10-rc3-mm1 kernel), however, it was unintentionally removed when arch/m32r/kernel/irq.c was modified to employ the generic hardirq framework (CONFIG_GENERIC_HARDIRQ) in my previous patch. [PATCH 2.6.10-rc3-mm1] m32r: Use generic hardirq framework http://www.ussg.iu.edu/hypermail/linux/kernel/0412.2/0358.html The following patch fixes the above problem.

* [PATCH] Don't export machine_restart, machine_halt, or machine_power_off.Eric W. Biederman2005-07-26
| | | | | | | | | | | | machine_restart, machine_halt and machine_power_off are machine specific hooks deep into the reboot logic, that modules have no business messing with. Usually code should be calling kernel_restart, kernel_halt, kernel_power_off, or emergency_restart. So don't export machine_restart, machine_halt, and machine_power_off so we can catch buggy users.

* [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.

* [PATCH] m32r: framebuffer device supportHirokazu Takata2005-07-07
| | | | | | | | | | | | | | | | | | This patch is for supporting Epson s1d13xxx framebuffer device for m32r. # Sorry, a little bigger. The Epson s1d13806 is already supported by 2.6.12 kernel, and its driver is placed as drivers/video/s1d13xxxfb.c. For the m32r, a header file include/asm-m32r/s1d13806.h was prepared for several m32r target platforms. It was originally generated by an Epson tool S1D13806CFG.EXE, and modified manually for the m32r platforms.

* [PATCH] Cleanup patch for process freezingChristoph Lameter2005-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Establish a simple API for process freezing defined in linux/include/sched.h: frozen(process) Check for frozen process freezing(process) Check if a process is being frozen freeze(process) Tell a process to freeze (go to refrigerator) thaw_process(process) Restart process frozen_process(process) Process is frozen now 2. Remove all references to PF_FREEZE and PF_FROZEN from all kernel sources except sched.h 3. Fix numerous locations where try_to_freeze is manually done by a driver 4. Remove the argument that is no longer necessary from two function calls. 5. Some whitespace cleanup 6. Clear potential race in refrigerator (provides an open window of PF_FREEZE cleared before setting PF_FROZEN, recalc_sigpending does not check PF_FROZEN). This patch does not address the problem of freeze_processes() violating the rule that a task may only modify its own flags by setting PF_FREEZE. This is not clean in an SMP environment. freeze(process) is therefore not SMP safe! Signed-off-by: Christoph Lameter <christoph@lameter.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [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] remove non-DISCONTIG use of pgdat->node_mem_mapDave Hansen2005-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch effectively eliminates direct use of pgdat->node_mem_map outside of the DISCONTIG code. On a flat memory system, these fields aren't currently used, neither are they on a sparsemem system. There was also a node_mem_map(nid) macro on many architectures. Its use along with the use of ->node_mem_map itself was not consistent. It has been removed in favor of two new, more explicit, arch-independent macros: pgdat_page_nr(pgdat, pagenr) nid_page_nr(nid, pagenr) I called them "pgdat" and "nid" because we overload the term "node" to mean "NUMA node", "DISCONTIG node" or "pg_data_t" in very confusing ways. I believe the newer names are much clearer. These macros can be overridden in the sparsemem case with a theoretically slower operation using node_start_pfn and pfn_to_page(), instead. We could make this the only behavior if people want, but I don't want to change too much at once. One thing at a time. This patch removes more code than it adds. Compile tested on alpha, alpha discontig, arm, arm-discontig, i386, i386 generic, NUMAQ, Summit, ppc64, ppc64 discontig, and x86_64.

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!
