2011-10-21tcp: add const qualifiers where possibleEric Dumazet
Adding const qualifiers to pointers can ease code review, and spot some bugs. It might allow compiler to optimize code further. For example, is it legal to temporary write a null cksum into tcphdr in tcp_md5_hash_header() ? I am afraid a sniffer could catch the temporary null value...

2011-10-21HID: hid-magicmouse: Magic Trackpad has 1 button, not 2Daniel van Vugt
hid-magicmouse was advertising the Apple Magic Trackpad as having 2 buttons (left and right) when it actually only has 1 button. Advertising multiple buttons makes Xorg disable all button 2 and 3 emulation (using multi-finger clicks). So Xorg users don't get working right/middle-click emulation out of the box. This patch makes hid-magicmouse correctly only report one real button for Magic Trackpad, which in turn makes Xorg enable multi-finger click support to emulate right/middle buttons.

2011-10-21macvtap: Fix the minor device number allocationEric W. Biederman
On systems that create and delete lots of dynamic devices the 31bit linux ifindex fails to fit in the 16bit macvtap minor, resulting in unusable macvtap devices. I have systems running automated tests that that hit this condition in just a few days. Use a linux idr allocator to track which mavtap minor numbers are available and and to track the association between macvtap minor numbers and macvtap network devices. Remove the unnecessary unneccessary check to see if the network device we have found is indeed a macvtap device. With macvtap specific data structures it is impossible to find any other kind of networking device. Increase the macvtap minor range from 65536 to the full 20 bits that is supported by linux device numbers. It doesn't solve the original problem but there is no penalty for a larger minor device range. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S.

2011-10-20drm/i915/panel: Always record the backlight level again (but cleverly)Takashi Iwai
The commit 47356eb67285014527a5ab87543ba1fae3d1e10a introduced a mechanism to record the backlight level only at disabling time, but it also introduced a regression. Since intel_lvds_enable() may be called without disabling (e.g. intel_lvds_commit() calls it unconditionally), the backlight gets back to the last recorded value. For example, this happens when you dim the backlight, close the lid and open the lid, then the backlight suddenly goes to the brightest. This patch fixes the bug by recording the backlight level always when changed via intel_panel_set_backlight(). And, intel_panel_{enable|disable}_backlight() call the internal function not to update the recorded level wrongly.

2011-10-20drm/i915: add PLL sharing support to handle 3 pipesJesse Barnes
Add two new fields to the intel_crtc struct for 3 pipe support: no_pll and use_pll_a. The no_pll field is only set on the 3rd pipe to indicate that it doesn't have a PLL of its own and so shouldn't try to write the main PLL regs. The use_pll_a field controls which PLL pipe 3 will share, A or B. The core code will try to share PLLs with whichever pipe has the same timings, rejecting the mode set if none is found. This means that pipe 3 must always be set after one of the other pipes has been configured with real PLL settings.
