This patch is preparation for further patches (pci probing) to allow allocated structures to be private data in pci_dev structure. Union two different structures used in the driver (hw_conf and port/board descriptor) to another 2: port and board not to initialize 2 different things and to have ports contained in board structure.

Change cloned experimental driver according to original 1.9.1 moxa driver. Some int->ulong conversions, outb ~UART_IER_THRI constant. Remove commented stuff. I also added printk line with info, if somebody wants to test it, he may contact me as I can potentially debug the driver with him or just to confirm it works properly. Signed-off-by:

Fix the locking of signal->tty. Use ->sighand->siglock to protect ->signal->tty; this lock is already used by most other members of ->signal/->sighand. And unless we are 'current' or the tasklist_lock is held we need ->siglock to access ->signal anyway. (NOTE: sys_unshare() is broken wrt ->sighand locking rules) Note that tty_mutex is held over tty destruction, so while holding tty_mutex any tty pointer remains valid. Otherwise the lifetime of ttys are governed by their open file handles. This leaves some holes for tty access from signal->tty (or any other non file related tty access). It solves the tty SLAB scribbles we were seeing. (NOTE: the change from group_send_sig_info to __group_send_sig_info needs to be examined by someone familiar with the security framework, I think it is safe given the SEND_SIG_PRIV from other __group_send_sig_info invocations) [schwidefsky@de.ibm.com: 3270 fix] [akpm@osdl.org: various post-viro fixes] Signed-off-by:Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by:

The IPMI BT subdriver has been patched to survive "long busy" timeouts seen during firmware upgrades and resets. The patch never returns the HOSED state, synthesizes response messages with meaningful completion codes, and recovers gracefully when the hardware finishes the long busy. The subdriver now issues a "Get BT Capabilities" command and properly uses those results. More informative completion codes are returned on error from transaction starts; this logic was propogated to the KCS and SMIC subdrivers. Finally, indent and other style quirks were normalized.

Make sure to delay a little in the IPMI poll routine so we can pass in a timeout time and thus time things out. Signed-off-by:
-
Corey Minyard authored
When the IPMI message handler requested that the interface look for events, the ipmi_si driver would request flags, see if the event buffer full flag was set, then request events. It's better to just send the request for events, as it cuts one message out of the transaction if there happens to be events, and it will fetch events even if the event buffer was not full.

Some commands and operations on a BMC can cause the BMC to "go away" for a while. This can cause the automatic flag processing and other things of that nature to timeout and generate annoying logs, or possibly cause other bad things to happen when in firmware update mode. Add detection of those commands (cold reset, warm reset, and any firmware command) and turns off automatic processing for 30 seconds. It also add a manual override either way. Signed-off-by:

This modifies the IPMI driver so that a lower-level interface can be dynamically removed while in use so it can support hot-removal of hardware. It also adds the ability to specify and dynamically change the IPMI interface the watchdog timer and the poweroff code use. Signed-off-by:

Add the product id to the driver model platform device name, in addition to the device id. The IPMI spec does not require that individual BMCs in a system have unique devices IDs, but it does require that the product id/device id combination be unique. This also removes a redundant check and cleans up error handling when the sysfs registration fails. Signed-off-by:

Fix compile errors on mismatch between generic HDLC and synclink drivers. Notes: generic HDLC support for synclink drivers is *optional* so you can't just use depend on in Kconfig This solution is deemed the best after 7 months of review and criticism by many developers including AKPM.

This a set of fixes mostly to make the driver actually work: 1. Actually select the line for setting parameters and receiver disable/enable. 2. Select the line for receive and transmit interrupt handling correctly. 3. Report the transmitter empty state correctly. 4. Set the I/O type of ports correctly. 5. Perform polled transmission correctly. 6. Don't fix the console line at ttyS3. 7. Magic SysRq support. 8. Various small bits here and there. Tested with a DECstation 2100 (thanks Flo for making this possible). [akpm@osdl.org: fix typo] Signed-off-by:

Clean up several code points in which the return code from misc_register is not handled properly. Several modules failed to deregister various hooks when misc_register fails, and this patch cleans them up. Also there are a few modules that legitimately don't care about the failure status of misc register. These drivers however unilaterally call misc_deregister on module unload. Since misc_register doesn't initialize the list_head in the init_routine if it fails, the deregister operation is at risk for oopsing when list_del is called. The initial solution was to manually init the list in the miscdev structure in each of those modules, but the consensus in this thread was to consolodate and do that universally inside misc_register.
