2006-02-06[IA64-SGI] Shub2 BTE address fixRuss Anderson
After converting the cpu physical address to shub2 physical addressing, the address was run through TO_PHYS() which clobbered a high node offset bit causing the BTE to fail on shub2 nodes with large memory. This fix corrects that problem. Signed-off-by: Russ Anderson (rja@sgi.com) Signed-off-by: Tony Luck <tony.luck@intel.com>

2006-02-03[PATCH] Export cpu topology in sysfsZhang, Yanmin
The patch implements cpu topology exportation by sysfs. Items (attributes) are similar to /proc/cpuinfo. 1) /sys/devices/system/cpu/cpuX/topology/physical_package_id: represent the physical package id of cpu X; 2) /sys/devices/system/cpu/cpuX/topology/core_id: represent the cpu core id to cpu X; 3) /sys/devices/system/cpu/cpuX/topology/thread_siblings: represent the thread siblings to cpu X in the same core; 4) /sys/devices/system/cpu/cpuX/topology/core_siblings: represent the thread siblings to cpu X in the same physical package; To implement it in an architecture-neutral way, a new source file, driver/base/topology.c, is to export the 5 attributes. If one architecture wants to support this feature, it just needs to implement 4 defines, typically in file include/asm-XXX/topology.h. The 4 defines are: #define topology_physical_package_id(cpu) #define topology_core_id(cpu) #define topology_thread_siblings(cpu) #define topology_core_siblings(cpu) The type of **_id is int. The type of siblings is cpumask_t. To be consistent on all architectures, the 4 attributes should have deafult values if their values are unavailable. Below is the rule. 1) physical_package_id: If cpu has no physical package id, -1 is the default value. 2) core_id: If cpu doesn't support multi-core, its core id is 0. 3) thread_siblings: Just include itself, if the cpu doesn't support HT/multi-thread. 4) core_siblings: Just include itself, if the cpu doesn't support multi-core and HT/Multi-thread. So be careful when declaring the 4 defines in include/asm-XXX/topology.h. If an attribute isn't defined on an architecture, it won't be exported. Thank Nathan, Greg, Andi, Paul and Venki. The patch provides defines for i386/x86_64/ia64.

2006-02-02[IA64] avoid broken SAL_CACHE_FLUSH implementationsBjorn Helgaas
If SAL_CACHE_FLUSH drops interrupts, complain about it and fall back to using PAL_CACHE_FLUSH instead. This is to work around a defect in HP rx5670 firmware: when an interrupt occurs during SAL_CACHE_FLUSH, SAL drops the interrupt but leaves it marked "in-service", which leaves the interrupt (and others of equal or lower priority) masked.

2006-01-26[IA64-SGI] Recursive flags do not work for selective buildsKeith Owens
arch/ia64/sn/Makefile sets CPPFLAGS, expecting that setting to propogate to all the subdirectories. For a normal build with its recursive descent it does work, but doing a selective build like 'make arch/ia64/sn/kernel/io_init.i' does not do a recursive descent, it goes directly to arch/ia64/sn/kernel/Makefile so the flags do not get set.

Add hotplug cpu support to salinfo.c. The cpu_event field is a cpumask so use the cpu_* macros consistently, replacing the existing mixture of cpu_* and *_bit macros. Instead of counting the number of outstanding events in a semaphore and trying to track that count over user space context, interrupt context, non-maskable interrupt context and cpu hotplug, replace the semaphore with a test for "any bits set" combined with a mutex.

2006-01-13[IA64-SGI] Fix sn_flush_device_kernel & spinlock initializationPrarit Bhargava
This patch separates the sn_flush_device_list struct into kernel and common (both kernel and PROM accessible) structures. As it was, if the size of a spinlock_t changed (due to additional CONFIG options, etc.) the sal call which populated the sn_flush_device_list structs would erroneously write data (and cause memory corruption and/or a panic). This patch does the following: 1. Removes sn_flush_device_list and adds sn_flush_device_common and sn_flush_device_kernel. 2. Adds a new SAL call to populate a sn_flush_device_common struct per device, not per widget as previously done. 3. Correctly initializes each device's sn_flush_device_kernel spinlock_t struct (before it was only doing each widget's first device).

2006-01-13[IA64] Hole in IA64 TLB flushing from system threadsJack Steiner
I originally thought this was an bug only in the SN code, but I think I also see a hole in the generic IA64 tlb code. (Separate patch was sent for the SN problem). It looks like there is a bug in the TLB flushing code. During context switch, kernel threads (kswapd, for example) inherit the mm of the task that was previously running on the cpu. Normally, this is ok because the previous context is still loaded into the RR registers. However, if the owner of the mm migrates to another cpu, changes it's context number, and references a page before kswapd issues a tlb_purge for that same page, the purge will be done with a stale context number (& RR registers).
