kernel patch. This patch makes it work again. The MCA path is similarly broken. Patch will follow later.

Delete references to arch/ia64/tools; use standard sed script to generate offsets.h. This gets the dependencies right for offsets.h

run faster than break-based syscall stubs, even if there is no light-weight syscall handler. Adds a new boot command-line option "nolwsys" which can be used to turn off light-weight system call handlers. Good for performance measurement and (potentially) for debugging.

fix bit rot in signal debug printk.

Instead of using break, this one bubbles down into the kernel directly. This code works, but isn't performance optimal yet.

didn't preserve b6 and r11 anymore. Unfortunately, preserving them costs a few cycles (~5 cycles in the cached case). The uncached case is hopefully mostly unaffected because the number of cache-lines touched is the same (without preserving b6 and r11, the entry-patch _almost_ got away with touching a single 128-byte cacheline, but not quite, because r8 also had to be initialized).

Fix setting of current->thread.on_ustack flag in optimized syscall exit path. Tune break_fault for syscall execution. Break ia32_execve: the ia64_execve() hack that was there is too ugly for words; surely we can do better...

Here's another sn2 update. It includes a bunch of misc. bits: o a bunch of cleanup from hch o addition of DMA routine wrappers o update of other PCI routines o topology.h prototype addition.

This should get the CONFIG_PREEMPT to work again. We were trashing r20 by accident.

fails: shmctl(shmid, IPC_STAT, &shmid_ds) The patch corrects the definition of the ipc_perm32 structure.

This one is similar to msgctl. We should be calling sys_shmctl with struct shmid64_ds. In the absence of this patch: shmctl(shmid, IPC_SET, &shmid_ds) will fail.

IA-32 programs executing: msgctl(id, IPC_SET, &buf) currently fail with EPERM due to this bug.

Patch by Rohit Seth, Fengua Yu, and Arun Sharma: Please find attached a patch for kernel entry exit optimization. This is based on 2.5.69 kernel. The main items covered by this patch are: 1) Support for 16 bytes instructions as per SDM2.1 (CSD/SSD in pt_regs) 2) f10-f11 are added as additional scratch registers for kernel's use. 3) Re-arrange pt_regs to access less cache lines in system call. Reduce scratch register saving/restoring in system call path. 4) A few instruction reorg in low-level code.

This patch moves the kernel text and data into region 5 (0xa00...) by using a translation register to pin the entire area (i.e., no TLB faults). The 1st-order goal is to be able to boot a kernel even when there is no usable memory in the 64-128MB range. It is also a step towards enabling text-replication on NUMA.

This patch allows users to set the PMC to their default value, even though the value might conflict with the type of monitoring session. This is fine because default values ensure the monitor is not active.
