2011-08-24firmware loader: allow builtin firmware load even if usermodehelper is disabledLinus Torvalds
In commit a144c6a6c924 ("PM: Print a warning if firmware is requested when tasks are frozen") we not only printed a warning if somebody tried to load the firmware when tasks are frozen - we also failed the load. But that check was done before the check for built-in firmware, and then when we disallowed usermode helpers during bootup (commit 288d5abec831: "Boot up with usermodehelper disabled"), that actually means that built-in modules can no longer load their firmware even if the firmware is built in too. Which used to work, and some people depended on it for the R100 driver. So move the test for usermodehelper_is_disabled() down, to after checking the built-in firmware. This should fix: https://bugzilla.kernel.org/show_bug.cgi?id=40952 Reported-by: James Cloos <cloos@hjcloos.com> Bisected-by: Elimar Riesebieter <riesebie@lxtec.de> Cc: Michel Dänzer <michel@daenzer.net> Cc: Rafael Wysocki <rjw@sisk.pl> Cc: Greg Kroah-Hartman <gregkh@suse.de> Cc: Valdis Kletnieks <valdis.kletnieks@vt.edu> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-08-23staging: zcache: fix crash on high memory swapSeth Jennings
zcache_put_page() was modified to pass page_address(page) instead of the actual page structure. In combination with the function signature changes to tmem_put() and zcache_pampd_create(), zcache_pampd_create() tries to (re)derive the page structure from the virtual address. However, if the original page is a high memory page (or any unmapped page), this virt_to_page() fails because the page_address() in zcache_put_page() returned NULL. This patch changes zcache_put_page() and zcache_get_page() to pass the page structure instead of the page's virtual address, which may or may not exist.

2011-08-23TTY: serial, document ignoring of uart->ops->startup errorJiri Slaby
When a user has SYS_ADMIN capabilities and uart->ops->startup returns an error in uart_startup, we silently drop the error. We then return 0 and behave as if it didn't fail. (Not quite, since we set TTY_IO_ERROR bit and leave ASYNC_INITIALIZED bit cleared.) This all is to allow setserial to work with improperly configured or unconfigured ports. User can thus set port properties and reconfigure properly. This patch only documents this behavior.

2011-08-23TTY: pty, fix pty countingJiri Slaby
tty_operations->remove is normally called like: queue_release_one_tty ->tty_shutdown ->tty_driver_remove_tty ->tty_operations->remove However tty_shutdown() is called from queue_release_one_tty() only if tty_operations->shutdown is NULL. But for pty, it is not. pty_unix98_shutdown() is used there as ->shutdown. So tty_operations->remove of pty (i.e. pty_unix98_remove()) is never called. This results in invalid pty_count. I.e. what can be seen in /proc/sys/kernel/pty/nr. I see this was already reported at: https://lkml.org/lkml/2009/11/5/370 But it was not fixed since then. This patch is kind of a hackish way. The problem lies in ->install. We allocate there another tty (so-called tty->link). So ->install is called once, but ->remove twice, for both tty and tty->link. The fix here is to count both tty and tty->link and divide the count by 2 for user. And to have ->remove called, let's make tty_driver_remove_tty() global and call that from pty_unix98_shutdown() (tty_operations->shutdown). While at it, let's document that when ->shutdown is defined, tty_shutdown() is not called. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: Alan Cox <alan@linux.intel.com> Cc: "H.

2011-08-238250: Fix race condition in serial8250_backup_timeout().Al Cooper
This is to fix an issue where output will suddenly become very slow. The problem occurs on 8250 UARTS with the hardware bug UART_BUG_THRE. BACKGROUND For normal UARTs (without UART_BUG_THRE): When the serial core layer gets new transmit data and the transmitter is idle, it buffers the data and calls the 8250s' serial8250_start_tx() routine which will simply enable the TX interrupt in the IER register and return. This should immediately fire a THRE interrupt and begin transmitting the data. For buggy UARTs (with UART_BUG_THRE): merely enabling the TX interrupt in IER does not necessarily generate a new THRE interrupt. Therefore, a background timer periodically checks to see if there is pending data, and starts transmission if that is the case. The bug happens on SMP systems when the system has nothing to transmit, the transmit interrupt is disabled and the following sequence occurs: - CPU0: The background timer routine serial8250_backup_timeout() starts and saves the state of the interrupt enable register (IER) and then disables all interrupts in IER. NOTE: The transmit interrupt (TI) bit is saved as disabled. - CPU1: The serial core gets data to transmit, grabs the port lock and calls serial8250_start_tx() which enables the TI in IER. - CPU0: serial8250_backup_timeout() waits for the port lock. - CPU1: finishes (with TI enabled) and releases the port lock. - CPU0: serial8250_backup_timeout() calls the interrupt routine which will transmit the next fifo's worth of data and then restores the IER from the previously saved value (TI disabled). At this point, as long as the serial core has more transmit data buffered, it will not call serial8250_start_tx() again and the background timer routine will slowly transmit the data. The fix is to have serial8250_start_tx() get the port lock before it saves the IER state and release it after restoring IER. This will prevent serial8250_start_tx() from running in parallel.

When the line discipline install fails for reasons such as missing user-space UIM or broken communication between UIM and ST driver, then the ST attempts/retries to request for ldisc installation again.

2011-08-22drivers:misc: ti-st: reinit completion before sendPavan Savoy
download firmware behaves differently at different times, when logs are enabled and the system is loaded, the wait_for_completion is able to wait for every send, However during other times the wait does not happen. So, for reliability reinitializing the completion before every send, makes sure the wait happens for every send.

2011-08-22drivers:misc: ti-st: fail-safe on wrong pkt typeVijay Badawadagi
Texas Instrument's shared transport driver interpret incoming data from the UART based on the various protocol drivers registered to the driver such as btwilink driver or FM or GPS driver which provide logical channel IDs. In case of bad-behavior from chip such as HCI Event response for a GPS command or a HCI Event (h/w error event) for a FM response & In case of bad-behavior from UART driver such as dropping data bytes a fail-safe is required to avoid kernel panic.

2011-08-22drivers:misc: ti-st: reinit completion on ver readPavan Savoy
After the version information has been read, the completion which assists in wait_for_completion during the firmware send/wait sequence is being re-used and hence this needs to be re-initialised for fool proof firmware download retries.
