2005-06-18[PATCH] ARM SMP: Add support for startup of secondary processorsRussell King
Create a temporary page table to startup secondary processors. This page table must have a 1:1 virtual/physical mapping for the kernel in addition to the standard mappings to ensure that the secondary CPU can enable its MMU safely. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-06-16[PATCH] ARM: 2714/1: Fix the IB2 definitions for the Versatile platformCatalin Marinas

2005-06-13[IPV4]: Sysctl configurable icmp error source address.J. Simonetti
This patch alows you to change the source address of icmp error messages. It applies cleanly to 2.6.11.11 and retains the default behaviour. In the old (default) behaviour icmp error messages are sent with the ip of the exiting interface. The new behaviour (when the sysctl variable is toggled on), it will send the message with the ip of the interface that received the packet that caused the icmp error. This is the behaviour network administrators will expect from a router. It makes debugging complicated network layouts much easier. Also, all 'vendor routers' I know of have the later behaviour.

2005-06-08[PATCH] ppc64: Fix PER_LINUX32 behaviourPaul Mackerras
This patch fixes some bugs in the ppc64 PER_LINUX32 implementation, noted by Juergen Kreileder: * uname(2) doesn't respect PER_LINUX32, it returns 'ppc64' instead of 'ppc' * Child processes of a PER_LINUX32 process don't inherit PER_LINUX32 Along the way I took the opportunity to move things around so that sys_ppc32.c only has 32-bit syscall emulation functions and to remove the obsolete "fakeppc" command line option.

2005-06-08[PATCH] ia64: fix floating-point preemption problemPeter Chubb
There've been reports of problems with CONFIG_PREEMPT=y and the high floating point partition. This is caused by the possibility of preemption and rescheduling on a different processor while saving or restioirng the high partition. The only places where the FPU state is touched are in ptrace, in switch_to(), and where handling a floating-point exception. In switch_to() preemption is off. So it's only in trap.c and ptrace.c that we need to prevent preemption. Here is a patch that adds commentary to make the conditions clear, and adds appropriate preempt_{en,dis}able() calls to make it so. In trap.c I use preempt_enable_no_resched(), as we're about to return to user space where the preemption flag will be checked anyway.

2005-06-07[PATCH] AGP fix for Xen VMMKeir Fraser
When Linux is running on the Xen virtual machine monitor, physical addresses are virtualised and cannot be directly referenced by the AGP GART. This patch fixes the GART driver for Xen by adding a layer of abstraction between physical addresses and 'GART addresses'. Architecture-specific functions are also defined for allocating and freeing the GATT. Xen requires this to ensure that table really is contiguous from the point of view of the GART. These extra interface functions are defined as 'no-ops' for all existing architectures that use the GART driver.

2005-06-04[PATCH] s390: uml ptrace fixesBodo Stroesser
To make UML build and run on s390, I needed to do these two little changes: 1) UML includes some of the subarch's (s390) headers. I had to change one of them with the following one-liner, to make this compile. AFAICS, this change doesn't break compilation of s390 itself. 2) UML needs to intercept syscalls via ptrace to invalidate the syscall, read syscall's parameters and write the result with the result of UML's syscall processing. Also, UML needs to make sure, that the host does no syscall restart processing. On i386 for example, this can be done by writing -1 to orig_eax on the 2nd syscall interception (orig_eax is the syscall number, which after the interception is used as a "interrupt was a syscall" flag only. Unfortunately, s390 holds syscall number and syscall result in gpr2 and its "interrupt was a syscall" flag (trap) is unreachable via ptrace. So I changed the host to set trap to -1, if the syscall number is changed to an invalid value on the first syscall interception.

Great! FWIW I've briefly tested a modified version of usbatm using the list head in struct urb instead of creating a wrapper struct, and I haven't seen any failures yet.

The iseries has a bar graph on the front panel that shows how busy it is. The operating system sets and clears a bit in the CTRL register to control it.

2005-06-01[PATCH] ppc32/ppc64: cleanup /proc/device-treeBenjamin Herrenschmidt
This cleans up the /proc/device-tree representation of the Open Firmware device-tree on ppc and ppc64. It does the following things: - Workaround an issue in some Apple device-trees where a property may exist with the same name as a child node of the parent. We now simply "drop" the property instead of creating duplicate entries in /proc with random result... - Do not try to chop off the "@0" at the end of a node name whose unit address is 0. This is not useful, inconsistent, and the code was buggy and didn't always work anyway. - Do not create symlinks for the short name and unit address parts of a node. These were never really used, bloated the memory footprint of the device-tree with useless struct proc_dir_entry and their matching dentry and inode cache bloat. This results in smaller code, smaller memory footprint, and a more accurate view of the tree presented to userland.
