The Prestigio 157, an old no-name clone laptop uses input keys very similar to the Wistron 1557/MS2141 with the addition of BIOS-controlled wireless radio frequency kill switch. This patch adds support for the RF kill switch control and adds manual identification of the model. The Prestigio does not expose any recognisable identity via dmidecode and so requires manual selection at module init using force=1 keymap=prestigio Signed-off-by: TJ <ubuntu@tjworld.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

Commit 3d5cb60e ("Input: simplify name handling for certain input handles") introduced a regression for the EVIOCGNAME/JSIOCGNAME ioctl. Before this, patch, the platform device's name was given back to userspace which was good to identify devices. After this patch, the device is ("event%d", minor) which is not descriptive at all. This fixes the behaviour by taking dev->name.

This patch adds DMI information to automatically load the correct layout for the Maxdata Pro 7000X/DX notebook models. Such notebooks are clones of Fujitsu Amilo V2000, the hook for the v2000 is being used and I have tested that perfectly works. The immediate result of integrating this patch is that the five special buttons will work on these specific notebook models and that the RF killswitch will not be activated after suspend. This patch definitively obsoletes the fsam7400 module which I was still needing to enable wifi and to fix the RF killswitch suspend problem; in the current 2.6.30 kernel it is necessary to load the wistron_btns module with options 'force=1 keymap=1557/MS2141', which was not anyway a complete workaround.

Serio ports are not being restarted any longer because resume operations after hibernate do nothing, since the device has not been marked as suspended. This happens because suspend is only considering the SUSPEND event but not the FREEZE event. Note that this driver has still to migrate to dev_pm_ops, but this fixes this particular bug now.

Original patch by Marek Vasut, modified by Eric in: 1. use delayed work to simplify the debouncing 2. combine col_polarity/row_polarity into a single active_low field 3. use a generic bit array based XOR algorithm to detect key press/release, which should make the column assertion time shorter and code a bit cleaner 4. remove the ALT_FN handling, which is no way generic, the ALT_FN key should be treated as no different from other keys, and translation will be done by user space by commands like 'loadkeys'. 5. explicitly disable row IRQs and flush potential pending work, and schedule an immediate scan after resuming as suggested by Uli Luckas 6. incorporate review comments from many others Patch tested on Littleton/PXA310 (though PXA310 has a dedicate keypad controller, I have to configure those pins as generic GPIO to use this driver, works quite well, though), and Sharp Zaurus model SL-C7x0 and SL-C1000.

The touchscreen works in two modes, wait trigger mode and auto-semi mode. The device starts in wait trigger mode and waits until pressure is detected, then device sets WT_INT bit and raises an interrupt. The driver should put the device into auto-semi mode and prepare for reading first X and then Y coordinates. When coordinate data is ready the driver sets ADC_INT bit and raises interrupt again.

There's a bug in the mxser kernel module that still appears in the 2.6.29.4 kernel. mxser_get_ISA_conf takes a ioaddress as its first argument, by passing the not of the ioaddr, you're effectively passing 0 which means it won't be able to talk to an ISA card. I have tested this, and removing the ! fixes the problem.

In commit code, we scan buffers attached to a transaction. During this scan, we sometimes have to drop j_list_lock and then we recheck whether the journal buffer head didn't get freed by journal_try_to_free_buffers(). But checking for buffer_jbd(bh) isn't enough because a new journal head could get attached to our buffer head. So add a check whether the journal head remained the same and whether it's still at the same transaction and list. This is a nasty bug and can cause problems like memory corruption (use after free) or trigger various assertions in JBD code (observed).

The recent ->lookup() deadlock correction required the directory inode mutex to be dropped while waiting for expire completion. We were concerned about side effects from this change and one has been identified. I saw several error messages. They cause autofs to become quite confused and don't really point to the actual problem. Things like: handle_packet_missing_direct:1376: can't find map entry for (43,1827932) which is usually totally fatal (although in this case it wouldn't be except that I treat is as such because it normally is). do_mount_direct: direct trigger not valid or already mounted /test/nested/g3c/s1/ss1 which is recoverable, however if this problem is at play it can cause autofs to become quite confused as to the dependencies in the mount tree because mount triggers end up mounted multiple times. It's hard to accurately check for this over mounting case and automount shouldn't need to if the kernel module is doing its job. There was one other message, similar in consequence of this last one but I can't locate a log example just now. When checking if a mount has already completed prior to adding a new mount request to the wait queue we check if the dentry is hashed and, if so, if it is a mount point. But, if a mount successfully completed while we slept on the wait queue mutex the dentry must exist for the mount to have completed so the test is not really needed. Mounts can also be done on top of a global root dentry, so for the above case, where a mount request completes and the wait queue entry has already been removed, the hashed test returning false can cause an incorrect callback to the daemon. Also, d_mountpoint() is not sufficient to check if a mount has completed for the multi-mount case when we don't have a real mount at the base of the tree.

Michael Tokarev reported receiving a large packet could crash a machine with RTL8169 NIC. ( original thread at http://lkml.org/lkml/2009/6/8/192 ) Problem is this driver tells that NIC frames up to 16383 bytes can be received but provides skb to rx ring allocated with smaller sizes (1536 bytes in case standard 1500 bytes MTU is used) When a frame larger than what was allocated by driver is received, dma transfert can occurs past the end of buffer and corrupt kernel memory. Fix is to tell to NIC what is the maximum size a frame can be. This bug is very old, (before git introduction, linux-2.6.10), and should be backported to stable versions.
