Greg Ungerer [Fri, 3 Jun 2005 01:35:20 +0000]
[PATCH] m68knommu: fix scheduling and race problems in idle loop

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.

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" :)

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.

[PATCH] ext3: fix list scanning in __cleanup_transaction

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.

[PATCH] ppc32/ppc64: cleanup /proc/device-tree

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.

[PATCH] ppc64: Fix a device-tree bug on Apple's

Apple's Open Firmware has a funny bug when creating the /cpus nodes
where it leaves a dangling '\0' character in the CPU name which ends up
appearing in the full path of the node. This is bogus and
confuses /proc/device-tree badly.

This patch strips those bogus zero's from the node full path when
reading the device-tree from Open Firmware. The "name" property is not
modified and still contains the spurrious 0 (it basically contains 0
tailing 0 instead of one) but that shouldn't be a problem.

An equivalent patch for ppc32 will follow shortly

Here is my third attempt at a patch to further update the CompactPCI
hotplug driver infrastructure to address the pci_enable_device issue
discussed on the list as well as a few other issues I discovered during
some more testing.  This version addresses a few more issues pointed out
by Prarit Bhargava.  Changes include:
- cpci_enable_device and its recursive calling of pci_enable_device on
  new devices removed.
- Use list_rwsem to avoid slot status change races between disable_slot
  and check_slots.
- Fixed oopsing in cpci_hp_unregister_bus caused by calling list_del on
  a slot after calling pci_hp_deregister.
- Removed kfree calls in cleanup_slots since release_slot will have
  done it already.

[PATCH] USB: add sl811_cs support

This adds support for a CF-card USB Host adapter, the Ratoc REX-CFU1U, by
wrapping a PCMCIA driver around the existing "sl811-hcd" platform driver.

This CF card is especially useful for PDAs, which currently tend to have
no other solution for USB host capability.

[PATCH] USB: sl811-hcd fixes

Various fixes to the sl811-hcd driver:

  * Fix small glitches that crept in during recent evolution of usbcore's hcd
    glue layer, coupling endpoint state records to usbcore and active urbs.
    (As noted by folk whose boards weren't stuck on 2.6.9 kernels...)

  * Cope with various system-specific issues:
      - Some configurations (e.g. a CF-card uses this chip) have iospace
        addresses for the two registers, rather than memory mapped ones.
      - Some configurations do interesting things with IRQs; maybe the
        line is shared, or it doesn't support level triggering.
      - Not all boards can drive the chip reset line in software.

  * Address a potential race during unlinking.

  * Tweak probe/remove section info to handle the case where this segment
    of a platform bus is hotpluggable (e.g. CF card).  (The basic problem
    is that CONFIG_HOTPLUG is global, which is wrong since not all busses
    can hotplug even on hotplug-friendly systems...)  Also export the
    driver, so that the CF driver can depend on it.

Also removed some annoying end-of-line whitespace.

[PATCH] I2C: ALI1563 SMBus driver fix

This patch fixes "grave" bugs in i2c-ali1563 driver. It seems on recent
chipset revisions the HSTS_DONE is set only for block transfers, so we
must detect the end of ordinary transaction other way. Also due to missing
and mask, setting other transfer modes was not possible. Moreover the
continous byte mode transfer uses DAT0 for command rather than CMD command.
All those changes were tested with help of Chunhao Huang from Winbond.

I'm willing to maintain the driver. Second patch adds me as maintainer
if this is neccessary.

The receive queue lock is never taken in IRQs (and should never be) so
we can simply substitute bh for irq.

[NETFILTER]: Fix deadlock with ip_queue and tcp local input path.

When we have ip_queue being used from LOCAL_IN, then we end up with a
situation where the verdicts coming back from userspace traverse the TCP
input path from syscall context.  While this seems to work most of the
time, there's an ugly deadlock:

syscall context is interrupted by the timer interrupt.  When the timer
interrupt leaves, the timer softirq get's scheduled and calls
tcp_delack_timer() and alike.  They themselves do bh_lock_sock(sk),
which is already held from somewhere else -> boom.

I've now tested the suggested solution by Patrick McHardy and Herbert Xu to
simply use local_bh_{en,dis}able().
