Fix http://bugzilla.kernel.org/show_bug.cgi?id=5546 The cpu_khz global is not initialized and remains 0 if you boot with clock=pit, even if the processor does have a TSC. This may have bad ramifications since the variable is used in various places scattered around the kernel, though I didn't check them all to see if they can tolerate cpu_khz = 0. You can observe the problem by doing "cat /proc/cpuinfo"; the cpu MHz line says 0.000. The fix is trivial; call init_cpu_khz() from init_pit(), just as it's called from the timers/timer_foo.c:init_foo() for other values of foo. Cc: john stultz <johnstul@us.ibm.com> Signed-off-by:

The MPC8349 PIBs system has a expansion board with 6 PCI slots. We needed to update the IDSEL interrupt mapping for it to work properly. However, only PCI1 is supported as the first revision of this expansion board doesn't function properly for PCI2. For the time being we have zero'd out the entries for the IDSELs related to PCI2. When a functioning expansion board exists we can fix the table. Signed-off-by:

Enablement patch for the new PowerBooks (late 2005 edition). This enables the ATA controller, Gigabit ethernet and basic AGP setup. Bluetooth works out-of-the box after running hid2hci. Still remaining is to get the touchpad to work, the simple change of just adding the new USB ids isn't enough. Signed-off-by:

The pages_high - pages_low and pages_low - pages_min deltas are the asynch reclaim watermarks. As such, the should be in the same ratios as any other zone for highmem zones. It is the pages_min - 0 delta which is the PF_MEMALLOC reserve, and this is the region that isn't very useful for highmem. This patch ensures highmem systems have similar characteristics as non highmem ones with the same amount of memory, and also that highmem zones get similar reclaim pressures to other zones.

The address based work estimate for unmapping (for lockbreak) is and always was horribly inefficient for sparse mappings. The problem is most simply explained with an example: If we find a pgd is clear, we still have to call into unmap_page_range PGDIR_SIZE / ZAP_BLOCK_SIZE times, each time checking the clear pgd, in order to progress the working address to the next pgd. The fundamental way to solve the problem is to keep track of the end address we've processed and pass it back to the higher layers. From: Nick Piggin <npiggin@suse.de> Modification to completely get away from address based work estimate and instead use an abstract count, with a very small cost for empty entries as opposed to present pages. On 2.6.14-git2, ppc64, and CONFIG_PREEMPT=y, mapping and unmapping 1TB of virtual address space takes 1.69s; with the following patch applied, this operation can be done 1000 times in less than 0.01s From: Andrew Morton <akpm@osdl.org> With CONFIG_HUTETLB_PAGE=n: mm/memory.c: In function `unmap_vmas': mm/memory.c:779: warning: division by zero Due to zap_work -= (end - start) / (HPAGE_SIZE / PAGE_SIZE); So make the dummy HPAGE_SIZE non-zero Signed-off-by:

The file_lock spinlock sits close to mostly read fields of 'struct files_struct' In SMP (and NUMA) environments, each time a thread wants to open or close a file, it has to acquire the spinlock, thus invalidating the cache line containing this spinlock on other CPUS. So other threads doing read()/write()/... calls that use RCU to access the file table are going to ask further memory (possibly NUMA) transactions to read again this memory line. Move the spinlock to another cache line, so that concurrent threads can share the cache line containing 'count' and 'fdt' fields. It's worth up to 9% on a microbenchmark using a 4-thread 2-package x86 machine. See http://marc.theaimsgroup.com/?l=linux-kernel&m=112680448713342&w=2Signed-off-by:

The patch http://linux.bkbits.net:8080/linux-2.6/diffs/fs/locks.c@1.70??nav=index.html introduced a pretty nasty memory leak in the lease code. When freeing the lease, the code in locks_delete_lock() will correctly clean up the fasync queue, but when we return to fcntl_setlease(), the freed fasync entry will be reinstated. This patch ensures that we skip the call to fasync_helper() when we're freeing up the lease. Signed-off-by:
