2007-12-19[IA64] Fix Altix BTE error return statusRuss Anderson
The Altix shub2 BTE error detail bits are in a different location than on shub1. The current code does not take this into account resulting in all shub2 BTE failures mapping to "unknown". This patch reads the error detail bits from the proper location, so the correct BTE failure reason is returned for both shub1 and shub2.

2007-12-19[IA64] set_thread_area fails in IA32 chrootIan Wienand
I tried to upgrade an IA32 chroot on my IA64 to a new glibc with TLS. It kept dying because set_thread_area was returning -ESRCH (bugs.debian.org/451939). I instrumented arch/ia64/ia32/sys_ia32.c:get_free_idx() and ended up seeing output like [pid] idx desc->a desc->b ----------------------------- [2710] 0 -> c6b0ffff 40dff31b [2710] 1 -> 0 0 [2710] 2 -> 0 0 [2710] 0 -> c6b0ffff 40dff31b [2710] 1 -> c6b0ffff 40dff31b [2710] 2 -> 0 0 [2711] 0 -> c6b0ffff 40dff31b [2711] 1 -> c6b0ffff 40dff31b [2711] 2 -> 48c0ffff 40dff317 which suggested to me that TLS pointers were surviving exec() calls, leading to GDT pointers filling up and the eventual failure of get_free_idx().

2007-12-18[IA64] Avoid unnecessary TLB flushes when allocating memoryde Dinechin, Christophe (Integrity VM)
Improve performance of memory allocations on ia64 by avoiding a global TLB purge to purge a single page from the file cache. This happens whenever we evict a page from the buffer cache to make room for some other allocation. Test case: Run 'find /usr -type f | xargs cat > /dev/null' in the background to fill the buffer cache, then run something that uses memory, e.g. 'gmake -j50 install'. Instrumentation showed that the number of global TLB purges went from a few millions down to about 170 over a 12 hours run of the above. The performance impact is particularly noticeable under virtualization, because a virtual TLB is generally both larger and slower to purge than a physical one.

While it's not strictly necessary to have the BSS in the resource tree (the actual collision detection is done in the reserve_bootmem() function before), the usage of the BSS resource should be presented to the user in /proc/iomem just as Kernel data and Kernel code.
