2011-09-29staging: nvec: Add a udelay(100) to nvec_interruptJulian Andres Klode
As the comment indicates, adding that udelay seems to improve the stability of the communication, although it is not known why this is the case. Signed-off-by: Julian Andres Klode <jak@jak-linux.org> Acked-by: Marc Dietrich <marvin24@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-09-29staging: nvec: Add battery quirk to ignore incomplete responsesJulian Andres Klode
The nvec_power system polls nvec for battery information. In some cases, that part seems to be overloaded and unable to respond fast in which case it sends an incomplete response. We need to mark the transfer as completed, though, in order to prevent endless retries which can kill nvec.

2011-09-29staging: nvec: ps2: Always sample 4 bytes instead of just 1Julian Andres Klode
Get 4 bytes of data from nvec at once instead of just a single byte. This makes the driver more similar to nvidias and might improve reliability. Signed-off-by: Julian Andres Klode <jak@jak-linux.org> Acked-by: Marc Dietrich <marvin24@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-09-29staging: nvec: Handle filled up RX buffersJulian Andres Klode
If no RX buffer is available in state 1, jump to state 0 again. This will produce an incredible amount of warnings, but it is not supposed to happen anyway.

2011-09-29staging: nvec: Allow TX buffers only in the upper 75% of the poolJulian Andres Klode
Allow TX buffers to be allocated only in the upper 75% of the pool to avoid a completely filled buffer preventing the driver from processing responses. This also improves performance, as RX allocations do not require checking buffers allocated for TX unless there are more than 16 incoming messages -- which is highly unlikely. An earlier version used the lower 75% for TX messages, but that was considered to be not that effective due to the overlaps of RX and TX buffers mentioned above.

Rewrite the interrupt handler to use a state machine similar to that found in the various kernels for the Advent Vega.

2011-09-29Staging: bcm: Alter LOC for readability/understandability purposesKevin McKinney
This patch alters a line of code to make it more readable and easier to understand. The purpose of the original line of code was to compute the amount of memory to request from kmalloc. This mulit-step algorithm was being done in one line of code, thus making it more difficult to understand. Therefore, I split this algorithm into three logical steps.

2011-09-29Staging: bcm: Add min/max restrictions for IOCTL_BCM_REGISTER_READ_PRIVATEKevin McKinney
This patch fixes two issues within bcm/Bcmchar.c. The first condition in the or statement checks if variable IoBuffer.OutputLength, defined from user space, is greater than the maximum value allowed for an unsigned short. IoBuffer.OutputLength is then used in a kmalloc call to return a pointer to memory. If this size is greater than an unsigned short, it becomes useless. The second condition in the or statement checks if the same variable, IoBuffer.OutputLength is equal to zero before invoking the kmalloc call. In this case, if a zero size is sent to kmalloc, a valid pointer to memory is returned instead of the expected NULL.

2011-09-29bna: Add Callback to Fix RXQ StopRasesh Mody
Change details: - Add a callback in the BNA, which is called before sending FW command to stop RxQs. After this callback is called, driver should not post anymore Rx buffers to the RxQ. This addresses a small window where driver posts Rx buffers while FW is stopping/has stopped the RxQ. - Registering callback function, rx_stall_cbfn, during bna_rx_create. Invoking callback function, rx_stall_cbfn, before sending rx_cfg_clr command to FW - Bnad_cb_rx_stall implementation - set a flag in the Rxq to mark buffer posting disabled state. While posting buffers check for the above flag. Signed-off-by: Gurunatha Karaje <gkaraje@brocade.com> Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S.

2011-09-29TTY: snyclinkmp: forever loop in tx_load_dma_buffer()Dan Carpenter
My main concern here was the line that said: copy_count = min_t(unsigned short,count,SCABUFSIZE); "count" is an unsigned int here so the cast to unsigned short truncates the upper bits. So if count is 0x10000 then copy_count is 0 and the loop never exits. "count" comes from skb->len in hdlcdev_xmit(). The other min_t() changes are just cleanups.

2011-09-29user namespace: usb: make usb urbs user namespace aware (v2)Serge Hallyn
Add to the dev_state and alloc_async structures the user namespace corresponding to the uid and euid. Pass these to kill_pid_info_as_uid(), which can then implement a proper, user-namespace-aware uid check. Changelog: Sep 20: Per Oleg's suggestion: Instead of caching and passing user namespace, uid, and euid each separately, pass a struct cred. Sep 26: Address Alan Stern's comments: don't define a struct cred at usbdev_open(), and take and put a cred at async_completed() to ensure it lasts for the duration of kill_pid_info_as_cred().

2011-09-29xen: allow balloon driver to use more than one memory regionDavid Vrabel
Allow the xen balloon driver to populate its list of extra pages from more than one region of memory. This will allow platforms to provide (for example) a region of low memory and a region of high memory. The maximum possible number of extra regions is 128 (== E820MAX) which is quite large so xen_extra_mem is placed in __initdata. This is safe as both xen_memory_setup() and balloon_init() are in __init. The balloon regions themselves are not altered (i.e., there is still only the one region).
