      s390: remove driver_data direct access of struct device · dff59b64
      由 Greg Kroah-Hartman 提交于 
      In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

Thanks to Sebastian Ott <sebott@linux.vnet.ibm.com> for fixing a few
typos in my original version of this patch.

      [PATCH] s390: minor s390 network driver fixes · 4c7ae6ea
      由 Frank Pavlic 提交于 
      Hi Jeff,
this is a RESEND of the nine s390 network driver patches.
I finally found  that my kmail corrupted almost every patch
I sent the last time. Please apply these 9 patches and forget
about my first attempt! Sorry for the delay, I had some fights
with sendmail, IMAP and mutt configuration.

Frank

[RESEND PATCH 1/9] s390: minor s390 network driver fixes

From: Frank Pavlic <fpavlic@de.ibm.com>
	- iucv driver:
          use do { } while (0) constructs
	  instead of empty defines to avoid compile bugs.
        - ctc driver:
          missing lock initialization added
        - lcs driver:
          BUG_ON usage was removed accidently
	  with the last lcs patch.
          Put them back in place.

      [PATCH] s390: lcs driver bug fixes and improvements [1/2] · 27eb5ac8
      由 Klaus Wacker 提交于 
      	Several problems occured with lcs device driver:
	 - device not operational anymore after cable pull/plug-in.
       	 - unpredictable results occured, e.g. kernel panic
	   using cards of type QD8F.
	 - STOPLAN and delete multicast address command
           were not proper recognized by OSA card under heavy network workload.
       	 - channel/device error checks missing in interrupt handler.
	To fix all problems at once recovery of lcs devices has been improved.
	missing error checks in lcs interrupt handler has been added.
	Once a hardware problem occurs lcs will recover the device now properly.

      由 Frank Pavlic 提交于 
      [patch 1/2] s390: lcs performance enhancements

From: Klaus Wacker <kdwacker@de.ibm.com>
	- When flood pinging (with large packet size) an LCS device,
	  about 90 % of all packets are dropped by driver.
	- increased number of lcs IO buffers to 32.
	- use netif_stop_queue/netif_wake_queue in lcs_start_xmit routine
	- don't lock the whole xmit routine but just the piece of code where
	  tx_buffer is touched.

      [PATCH] s390: debug feature changes · 66a464db
      由 Michael Holzheu 提交于 
      This patch changes the memory allocation method for the s390 debug feature.
Trace buffers had been allocated using the get_free_pages() function before.
Therefore it was not possible to get big memory areas in a running system due
to memory fragmentation.  Now the trace buffers are subdivided into several
subbuffers with pagesize.  Therefore it is now possible to allocate more
memory for the trace buffers and more trace records can be written.

In addition to that, dynamic specification of the size of the trace buffers is
implemented.  It is now possible to change the size of a trace buffer using a
new debugfs file instance.  When writing a number into this file, the trace
buffer size is changed to 'number * pagesize'.

In the past all the traces could be obtained from userspace by accessing files
in the "proc" filesystem.  Now with debugfs we have a new filesystem which
should be used for debugging purposes.  This patch moves the debug feature
from procfs to debugfs.

Since the interface of debug_register() changed, all device drivers, which use
the debug feature had to be adjusted.

      [PATCH] s390: set online race in the lcs driver · b5f9d55b
      由 Frank Pavlic 提交于 
      [patch 3/10] s390: set online race in the lcs driver.

From: Michael Holzheu <holzheu@de.ibm.com>

There is a race between lcs_stopcard() and lcs_open_device() which
can lead to the error 'lcs: Error in starting channel, rc=-16'.
lcs_open_device() is invoked when 'ifconfig up' is called due to a
hotplug event, which is caused by register_netdev(). In parallel
lcs_stopcard() is executed. Both functions are sending lcs commands.
The second invocation fails with -EBUSY (-16) as return value.
Move invocation of register_netdev() after invocation of lcs_stopcard
to avoid the race.

      [patch 2/10] s390: multicast address registration in lcs.

From: Michael Holzheu <holzheu@de.ibm.com>

When setting lcs devices online you can run into an endless loop,
because the code that registers the multicast addresses uses
list_for_each_entry instead of list_for_each_entry_safe.

      Linux-2.6.12-rc2 · 1da177e4
      由 Linus Torvalds 提交于 
      Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
