ia64: Make brl-branches to ia64_spinlock_contention work from modules.
Since these branches use a special calling-convention, we don't want to go through the PLT stubs normally used for cross-module calls. Also fix a 1-bit bug in the plt_reloc() function which got triggered now that the core code lives below the module code (due to the virtual mapping of the core).

[PATCH] ia64: work around race conditions in ia32 support code
This is an old problem, first reported in December 2001. The test case is a multithreaded application doing a large number of malloc()/free().
When running on a 16k page size kernel, the current algorithm creates a temporary page, copies data to that page, does a new mmap and copies back subpages from the temporary page. This leaves a window of opportunity open for another thread to unmap or change the data in such a way that the new page has stale data.
A patch was proposed which tries to do away with copying if the old page was writable. The patch was rejected because it could corrupt data in the MAP_SHARED case.

Since we found that most of the apps which ran into this problem were dealing with pages where the old data and new data are both anonymous, I reworked the above patch in such a way that we don't optimize for the MAP_SHARED case. Infact, the only case that we optimize is the case where the old and new mapping are both anonymous.

ia64: Still more gate DSO tuning. Turns out a linker bug prevented
us from building the gate DSO in a way that makes it fit in <= 1 page. If a fixed linker is available, we do it in this space-saving way now. Otherwise, we'll do it the old way (the gate DSO will then take up about 18KB instead of just ~3KB). Thanks to Roland McGrath for making this all work.

[PATCH] ia64: minor perfmon fixes
- remove extra include of asm/perfmon.h
- fix a bug if PFM_LOAD_CONTEXT by which it would not return an error if the task already had a context attached.

<[email protected]> (03/06/12 1.1063.9.93)
ia64: Split ia32-only definitions into separate ia32int.h header file.
This avoids polluting ia64 code with definitions that are correct for ia32 only (for example, the ELF-related definitions would otherwise collide with ia64 ELF definitions).

[PATCH] ia64: fix NULL pointer dereferences in perfmon
This patch fixes some NULL pointer
problems in perfmon.
- fixes NULL pointer derefence in perfmon_mckinley.h when context is not loaded
- fixes typo in pfm_write_pmcs()

[PATCH] ia64: Define ia64_max_iommu_merge_mask unconditionally
Define ia64_max_iommu_merge_mask even without CONFIG_PCI, so that the simulator can link.

[PATCH] ia64: Include lib/Kconfig for HPSIM
I found the attached patch necessary to allow compressed file systems to be used under the simulator. lib/Kconfig is needed to configure in the zlib routines.

ia64: Add back lost change for PCI_DMA_BUS_IS_PHYS.
<[email protected]> (03/06/10 1.1063.9.88)
ia64: No early printk for GENERIC.
Here is a patch to the ia64 Kconfig file that disables the EARLY_PRINTK menu option if a GENERIC kernel is selected.
As we discussed last week, EARLY_PRINTK doesn't work for GENERIC kernels because readb/readl are machvecs.
<[email protected]> (03/06/10 1.1063.9.87)

smpboot.c, acpi.c:
ia64: NR_CPUS and number of CPUs
While building a kernel for our 4-way Lion box, I made the mistake of setting NR_CPUS to 4. Little did I know that the Lion ACPI tables always list 8 CPUs (with only the first N enabled), and so the resulting kernel overflowed the smp_boot_data.cpu_phys_id array, crashed and burned.
<[email protected]> (03/06/10 1.1063.9.84)
handle_fpu_swa() doesn't scale well if multiple CPUs need concurrent fp assist. The problem lies with concurrent, potentially frequent updates of fpu_swa_count, which serves as the throttle for doing the printk(). A frenzy of concurrent updates will produce a frenzy of cacheline ping-ponging.
The fix is simple:
Only increment fpu_swa_count when the printk() is about to happen, which limits the increment to no more than four times every five seconds.

[PATCH] ia64: switch to perfmon2
This patch contains a major rewrite of the perfmon subsystem to bring it to version 2.0. This version is NOT compatible with the existing perfmon-1.x version which was in 2.5 and still is in 2.4 kernels. This new codebase brings a lot of new features including the ability to attach to already running tasks, the ability the follow clone2, the ability to write your own sampling buffer format via kernel modules. It is also much more robust than its 1.x counter-part. This version supports the Itanium, McKinley and Madison PMUs. This is beta quality code and extensions to the interface are planned.

[PATCH] ia64: max user stack size of main thread configurable via RLIMIT_STACK
Make the size of the user stack based on the stack rlimit. The stack hard stack size now defaults to 2GB, but can be increased
with ulimit up to 1/2 of the max mappable space in a region.
For 16k pages, this makes the max stack size 8TB.

[PATCH] ia64: compile fix for HP Sim serial/console
I was getting annoyed at having to mess around with the HP Simulator stuff when trying to compile generic kernels. Here's the fix that I came up with. It basically makes the HP Sim console another config option that depends on the HP sim serial code.
It also sticks a couple of run-time checks in the init functions to only setup and run the code on hpsim machines.
<[email protected]> (03/06/05 1.1063.9.76)
[PATCH] ia64: runtime platform detection for 2.5
This is a 2.5 version of the patch that I juggled around a couple of weeks ago. It's just a simple macro that allows one to check if the kernel is running on a specific ia64 platform.
<[email protected]> (03/06/05 1.1063.9.75)
ia64: Remove no longer needed show_trace_task().
<[email protected]> (03/06/04 1.1063.9.74)
ia64: Misc small fixe: adjust for 2-argument version of show_stack(), remove
left-over bits from the old task-creation/destruction hacks. Fix typo in comment for pgprot_noncached().

ia64: Fix unwinder bug which caused it to allocate more memory than strictly
necessary.
<[email protected]> (03/06/02 1.1063.9.70)
[PATCH] ia64: fix SAVE_RESET so OS INIT handler works again
The syscall optimization patches broke the OS INIT handler because SAVE_RESET was addressing relative to r12, which contains the virtual address of the stack pointer. Fixed by addressing relative to r2/r3 instead.
<[email protected]> (03/06/02 1.1063.9.69)
[PATCH] ia64: performance-tweak syscall exit path some more
Please find the attached patch that:
1. Moves user stack flag memory access before srlz.i;
2. Moves mov b6=r22 as late as possible.
3. Changes (pSys) to (pLvSys) in skip_rbs_switch: section. IA32 syscall set pSys=1 but pLvSys=0. It's not necessary to clear bank1 r16-r19 registers for IA32 syscall.
The number for leave_syscall is 268 cycles with this patch. The number is 295 cycles w/o this patch. It was 245 cycles with the original kee patched kernel. The 23 cycles come from restoring b6 operation which didn't exist in the orignal kee patch.

[PATCH] ia64: fix unwinder to call get_scratch_regs() only when really needed
Only call get_scratch_regs() when pt is really needed. The extraneous calls to get_scratch_regs() can otherwise pick up the wrong address for pt. For example, calling unw_access_ar(&info, UNW_AR_BSPSTORE,...) before pt_regs had been reached could trigger this bug.
<[email protected]> (03/05/30 1.1063.9.67)
[PATCH] ia64: IA-32 emulation patch: ptrace get_FPREGS bug fix
A bug-fix in IA-32 emulation ptrace code. The bug originally got introduced with the addition of FPXREGS support in ptrace.
The bug is in ptrace get/set FPREGS routine. gdb by default will not use FPREGS routines when FPXREGS routines are supported. So we may not see this bug during normal gdb operations. But, if gdb (or any other app) directly tries to get/set FPREGS (probably an old version of gdb), it will end with an segmentation fault due to this bug.
Attached patch fixes the issue. The patch is taken against 2.5.69. But it applies to 2.4 tree as well.
<[email protected]> (03/05/30 1.1063.9.66)
[PATCH] ia64: two small fixes (perfmon & GENERIC build)
the first patch moves some definitions
out of perfmon.c to perfmon.h (similar to what is in 2.4).
The second patch contains a fix for the generic built. I did it that way to avoid other problems such as SIMSCSI depends on SCSI. so simply hardcoding this in the MAkefile could cause other problems. Anyway, SIMSCI is not defaulting to y when HP_SIM is defined so it is not so different.

[PATCH] ia64: small patch for arch/ia64/lib/Makefile for xor.o
I was building 2.5 and noticed that if you have raid5 configured as a module, then the arch/ia64/lib/xor.S would not get built (gets a make error since c file not there).
Attached patch fixes that so xor.S gets built if raid5 is built-in or a module.
<[email protected]> (03/05/30 1.1063.9.62)
[PATCH] ia64: provide a more generic vtop patching infrastructure
We need sometimes to load the physical address of a kernel object. Often we can convert the virtual address to physical at execution time, but sometimes (either for performance reasons or during error recovery) we cannot to this. Patch the marked bundles to load the physical address.
<[email protected]> (03/05/30 1.1063.9.61)

<[email protected]> (03/05/30 1.1063.9.58)
ia64: Finish the fsyscall support (finally!). Now fsyscall stubs will
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.

ia64: Implement a first cut of a streamlined fsys_fallback_syscall.
Instead of using break, this one bubbles down into the kernel directly. This code works, but isn't performance optimal yet.
<[email protected]> (03/05/28 1.1063.9.53)
ia64: Make fsyscalls work again. They broke because the streamlined syscall path
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).

ia64: Lots of formatting fixes for the optimized syscall paths.
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...

ia64: Restructure pt_regs and optimize syscall path.
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.

[PATCH] ia64: put kernel into virtually mapped area
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.
