Re-work the m68knommu specific idle code according to suggestions from Nick Piggin <nickpiggin@yahoo.com.au>. A couple of rules that we need to follow: 1. Preempt should now disabled over idle routines. Should only be enabled to call schedule() then disabled again. 3. When cpu_idle finds (need_resched() == 'true'), it should call schedule(). It should not call schedule() otherwise. Also fix interrupt locking around the need_resched() and cpu stop state so that there is no race condition. Signed-off-by:

This "obvious" one-liner is needed to recognize Zaurus SL 6000; it just checks two GUIDs not just one. OSDL bugids #4512 and #4545 seem to be duplicates of this report. From: Gerald Skerbitz <gsker@tcfreenet.org> Signed-off-by:

Great! FWIW I've briefly tested a modified version of usbatm using the list head in struct urb instead of creating a wrapper struct, and I haven't seen any failures yet. So I tend to believe that your "should be" actually means "is" :) > > If it is, can it be guaranteed in future, e.g. > > by moving the list head into the public section of struct urb? > > In fact I'm not sure why it ever got called "private" to usbcore/hcds. > I thought the idea was that it should be like urb->status, reserved for > whoever controls the URB. OK then how about the following (essentially documentation) patch? Signed-off-by:Roman Kagan <rkagan@mail.ru> Acked-by:

This patch makes the code to provide modalias in sysfs for usb devices 56 bytes smaller in i386, while making it clear that the first part of the modalias string is the same no matter what the device class is. Signed-Off-By:

This patch adds a new driver for "Option" cards. This is a GSM data card, controlled by three "serial ports" which are connected via an OHCI adapter, all located on an oversized PC-Card. It's sold by several GSM service providers. Traditionally, this card has been accessed via the standard serial driver and appropriate vendor= and product= options. However, testing has revealed several problems with this approach, including hung data transfers and lost data blocks when receiving. Therefore, I've written a separate driver. Signed-off-by:

o use a semaphore instead of an opencoded and racy lock o move locking out of shaper_kick and into the callers - most just released the lock before calling shaper_kick o remove in_interrupt() tests. from ->close we can always block, from ->hard_start_xmit and timer context never Signed-off-by:

Now that we have HZ=1000 there is much less of a need for decr_overclock. Remove it. Leave spread_lpevents but move it into iSeries_setup.c. We should look at making event spreading the default some day. Signed-off-by:

The iseries has a bar graph on the front panel that shows how busy it is. The operating system sets and clears a bit in the CTRL register to control it. Instead of going to the complexity of using a thread info bit, just set and clear it in the idle loop. Also create two helper functions, ppc64_runlatch_on and ppc64_runlatch_off. Finally don't use the short form of the SPR defines. Signed-off-by:

Fix a bug in list scanning that can cause us to skip the last buffer on the checkpoint list (and hence fail to do any progress under some rather unfavorable conditions). The problem is we first do jh=next_jh and then test } while (jh!=last_jh); Hence we skip the last buffer on the list (if it was not the only buffer on the list). As we already do jh=next_jh; in the beginning of the loop we are safe to just remove the assignment in the end. It can happen that 'jh' will be freed at the point we test jh != last_jh but that does not matter as we never *dereference* the pointer. Signed-off-by:

Fix possible false assertion failure in log_do_checkpoint(). We might fail to detect that we actually made a progress when cleaning up the checkpoint lists if we don't retry after writing something to disk. The patch was confirmed to fix observed assertion failures for several users. When we flushed some buffers we need to retry scanning the list. Otherwise we can fail to detect our progress.

This cleans up the /proc/device-tree representation of the Open Firmware device-tree on ppc and ppc64. It does the following things: - Workaround an issue in some Apple device-trees where a property may exist with the same name as a child node of the parent. We now simply "drop" the property instead of creating duplicate entries in /proc with random result... - Do not try to chop off the "@0" at the end of a node name whose unit address is 0. This is not useful, inconsistent, and the code was buggy and didn't always work anyway. - Do not create symlinks for the short name and unit address parts of a node. These were never really used, bloated the memory footprint of the device-tree with useless struct proc_dir_entry and their matching dentry and inode cache bloat. This results in smaller code, smaller memory footprint, and a more accurate view of the tree presented to userland. Signed-off-by:
