Available from: ftp://ftp.kernel.org/pub/linux/kernel/people/wli/kernels/2.5.71/linux-2.5.71-bk2-wli-1.bz2
applies incrementally atop the bk2 snapshot.
So, where does one get a fanbase, anyway? NFI. Here's at least an attempt to acquire one, with desktop-oriented goodies to speed up top(1), apparently to the point where top(1) barely even registers on its own cpu usage reports even with 1s refreshes (900MHz P-III). It might also vaguely help people instrument heavy multitasking loads.
For what it's worth, the O(1) proc_pid_statm() patch also restores some of the old 2.4.x fields whose support was removed from 2.5.x.
Merged: - flow.c compilefix Well, I didn't really do any of the work, but at least I don't have to carry it around anymore.
Changes since 2.5.71-wli-1:
+ O(1) proc_pid_readdir() originally due to Manfred Spraul; figures out its position from a small pid hashtable rearrangement
+ O(1) proc_pid_statm() originally due to Ben LaHaise (I think); keeps count of the various proc_pid_statm() counters whenever twiddling ptes.
+ non-i386 highpmd fixes write stubs for non-i386 pmd twiddling functions
+ highpmd fixes a few mm/memory.c functions forgot to pass pmd pointers by reference
+ O(1) buffered_rmqueue() fixes correct small typo in CONFIG_SOFTWARE_SUSPEND code touched by it
+ i386 pagetable cache fixes Correct failure to reset tlb->freed, which resulted in wildly wrong mm->rss counts. Also define FREE_PTE_NR so CONFIG_PREEMPT compiles.
All 12 patches:
O(1) rmqueue_bulk() Implement deferred coalescing with list-of-lists -structured order 0 deferred queues so buffered_rmqueue() in O(1) expected time.
lowmem_page_address() microoptimization use page_to_pfn() to inherit its arch-specific microoptimizations
highpmd shove pmd's into highmem, by brute force
trivial /proc/ BKL removals Kill off some blatantly unnecessary BKL-grabbing in /proc/
i386 pagetable cache Resurrect the i386 pagetable cache
pgd_ctor Use slab ctors for i386 pgd's, and be safe with AGP and highpmd
O(1) proc_pid_readdir() originally due to Manfred Spraul; figures out its position from a small pid hashtable rearrangement
O(1) proc_pid_statm() originally due to Ben LaHaise (I think); keeps count of the various proc_pid_statm() counters whenever twiddling ptes.
