Change some file names and Kconfig settings so that this new module matches the new way of using wl12xx instead of wl1271.

2010-12-15wl12xx: Change TX queue to be per ACJuuso Oikarinen
With the current single-queue implementation traffic priorization is not working correctly - when using multiple BE streams and one, say VI stream, the VI stream will share bandwidth almost equally with the BE streams. To fix the issue, implement per AC queues, which are emptied in priority order to the firmware. To keep it relatively simple, maintain a global buffer count and global queue stop/wake instead of per-AC. With these changes, priorization appears to work just fine.

2010-12-15wl12xx: allow runtime changing of debug_levelEliad Peller
Currently, the debug level is set in compilation time (by the DEBUG_LEVEL const). This method has the advantage of compiling only the relevant messages, while optimizing out the unused ones. In order to allow runtime control over the debug_level, while optimizing out messages when debug messages are not needed, we combine some methods: 1. use dynamic_debug (pr_debug) rather then printk. 2. add debug_level module param in order to set debug level during insmod. 3. add debug_level sysfs file in order to allow dynamic control over the debug level. Since patches for pr_debug_hex_dump() implementation haven't been applied yet, we are still temporarly using print_hex_dump().

2010-12-15wl1271: fixed problem with WPS IEs in probe requestsGuy Eilam
Inclusion of a WPS IE in probe requests caused a problem in the driver due to the maximum size of the probe request template and the max_scan_ie_len values at initialization. Increased the size of probe request template to the maximum size allowed by the firmware. Struct wl12xx_probe_req_template, which was only used for calculating the max size of the probe request template, is no longer used and needed. max_scan_ie_len is used for validating the size of additional IEs in scan requests. Initialized the max_scan_ie_len field to the maximum size of the probe request template minus the ieee80211 header size.

2010-12-15wl12xx: add auto-arp supportEliad Peller

2010-12-15wl1271_sdio_test: Add module for sdio RX/TX testingRoger Quadros
This module enables individually generating RX and TX traffic over the SDIO bus on which the WL1271 chipset is connected. This is required to perform RF interference testing. The module takes 2 module parameters 'rx' and 'tx'. To generate RX traffic: modprobe wl1271_sdio_test rx=1 To generate TX traffic: modprobe wl1271_sdio_test tx=1 To generate both RX & TX traffic, set both rx and tx to 1. You can change the testing configuration at runtime by changing the rx & tx values at /sys/modules/wl1271_sdio_test/ To stop testing simply unload the module.

2010-12-15wl12xx: disable 11a channels when wl->enable_11a is knownLuciano Coelho
Disabling the 11a channels when not supported in the reg_notify function was not working as it should, because when the driver is initiailizing (and registering itself with mac80211), it would get the reg notification too early. At that point the driver wouldn't have received the NVS yet, so it wouldn't know whether 11a was supported. To fix this, we disable 11a channels when we read the NVS instead. Also, it is easier (and still safe) to set n_channels to zero instead of setting the disabled flag on every 11a channel. Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>

2010-12-14Input: define separate EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2Dmitry Torokhov
The desire to keep old names for the EVIOCGKEYCODE/EVIOCSKEYCODE while extending them to support large scancodes was a mistake. While we tried to keep ABI intact (and we succeeded in doing that, programs compiled on older kernels will work on newer ones) there is still a problem with recompiling existing software with newer kernel headers. New kernel headers will supply updated ioctl numbers and kernel will expect that userspace will use struct input_keymap_entry to set and retrieve keymap data. But since the names of ioctls are still the same userspace will happily compile even if not adjusted to make use of the new structure and will start miraculously fail in the field. To avoid this issue let's revert EVIOCGKEYCODE/EVIOCSKEYCODE definitions and add EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2 so that userspace can explicitly select the style of ioctls it wants to employ.

2010-12-13x86, vt-d: Handle previous faults after enabling fault handlingSuresh Siddha
Fault handling is getting enabled after enabling the interrupt-remapping (as the success of interrupt-remapping can affect the apic mode and hence the fault handling mode). Hence there can potentially be some faults between the window of enabling interrupt-remapping in the vt-d and the fault-handling of the vt-d units. Handle any previous faults after enabling the vt-d fault handling. For v2.6.38 cleanup, need to check if we can remove the dmar_fault() in the enable_intr_remapping() and see if we can enable fault handling along with enabling intr-remapping.

2010-12-13x86, vt-d: Quirk for masking vtd spec errors to platform error handling logicSuresh Siddha
On platforms with Intel 7500 chipset, there were some reports of system hang/NMI's during kexec/kdump in the presence of interrupt-remapping enabled. During kdump, there is a window where the devices might be still using old kernel's interrupt information, while the kdump kernel is coming up. This can cause vt-d faults as the interrupt configuration from the old kernel map to null IRTE entries in the new kernel etc. (with out interrupt-remapping enabled, we still have the same issue but in this case we will see benign spurious interrupt hit the new kernel). Based on platform config settings, these platforms seem to generate NMI/SMI when a vt-d fault happens and there were reports that the resulting SMI causes the system to hang. Fix it by masking vt-d spec defined errors to platform error reporting logic. VT-d spec related errors are already handled by the VT-d OS code, so need to report the same error through other channels.

Multiple devices use almost the same .cfg with minor differences. Use macro and remove the duplication. By doing this, reduce the chance for mistake while modify .cfg parameters Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
