2010-11-15i2c: Delete unused adapter IDsJean Delvare
Delete unused I2C adapter IDs. Special cases are: * I2C_HW_B_RIVA was still set in driver rivafb, however no other driver is ever looking for this value, so we can safely remove it. * I2C_HW_B_HDPVR is used in staging driver lirc_zilog, however no adapter ID is ever set to this value, so the code in question never runs. As the code additionally expects that I2C_HW_B_HDPVR may not be defined, we can delete it now and let the lirc_zilog driver maintainer rewrite this piece of code.

2010-11-15Fix gcc 4.5.1 miscompiling drivers/char/i8k.c (again)Jim Bos
The fix in commit 6b4e81db2552 ("i8k: Tell gcc that *regs gets clobbered") to work around the gcc miscompiling i8k.c to add "+m (*regs)" caused register pressure problems and a build failure. Changing the 'asm' statement to 'asm volatile' instead should prevent that and works around the gcc bug as well, so we can remove the "+m". [ Background on the gcc bug: a memory clobber fails to mark the function the asm resides in as non-pure (aka "__attribute__((const))"), so if the function does nothing else that triggers the non-pure logic, gcc will think that that function has no side effects at all. As a result, callers will be mis-compiled. Adding the "+m" made gcc see that it's not a pure function, and so does "asm volatile". The problem was never really the need to mark "*regs" as changed, since the memory clobber did that part - the problem was just a bug in the gcc "pure" function analysis - Linus ] Signed-off-by: Jim Bos <jim876@xs4all.nl> Acked-by: Jakub Jelinek <jakub@redhat.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: Andreas Schwab <schwab@linux-m68k.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-11-13i8k: Tell gcc that *regs gets clobberedJim Bos
More recent GCC caused the i8k driver to stop working, on Slackware compiler was upgraded from gcc-4.4.4 to gcc-4.5.1 after which it didn't work anymore, meaning the driver didn't load or gave total nonsensical output. As it turned out the asm(..) statement forgot to mention it modifies the *regs variable. Credits to Andi Kleen and Andreas Schwab for providing the fix.

2010-11-12ixgbe: Look inside vlan when determining offload protocol.Hao Zheng
Currently the skb->protocol field is used to setup various offloading parameters on transmit for the correct protocol. However, if vlan offloading is disabled or otherwise not used, the protocol field will be ETH_P_8021Q, not the actual protocol. This will cause the offloading to be not performed correctly, even though the hardware is capable of looking inside vlan tags. Instead, look inside the header if necessary to determine the correct protocol type. To some extent this fixes a regression from 2.6.36 because it was previously not possible to disable vlan offloading and this error case was not exposed.

2010-11-12PCI: fix pci_bus_alloc_resource() hang, prefer positive decodeBjorn Helgaas
When a PCI bus has two resources with the same start/end, e.g., pci_bus 0000:04: resource 2 [mem 0xd0000000-0xd7ffffff pref] pci_bus 0000:04: resource 7 [mem 0xd0000000-0xd7ffffff] the previous pci_bus_find_resource_prev() implementation would alternate between them forever: pci_bus_find_resource_prev(... [mem 0xd0000000-0xd7ffffff pref]) returns [mem 0xd0000000-0xd7ffffff] pci_bus_find_resource_prev(... [mem 0xd0000000-0xd7ffffff]) returns [mem 0xd0000000-0xd7ffffff pref] pci_bus_find_resource_prev(... [mem 0xd0000000-0xd7ffffff pref]) returns [mem 0xd0000000-0xd7ffffff] ... This happened because there was no ordering between two resources with the same start and end. A resource that had the same start and end as the cursor, but was not itself the cursor, was considered to be before the cursor. This patch fixes the hang by making a fixed ordering between any two resources. In addition, it tries to allocate from positively decoded regions before using any subtractively decoded resources. This means we will use a positive decode region before a subtractive decode one, even if it means using a smaller address.

2010-11-12drivers/video/backlight/adp8860_bl.c: fix ambient light zone overwrite handlingMichael Hennerich
This affects the get/set of the current Ambient Light Zone. Reading should return an integer between 1..3 (1 = Daylight, 2 = office, 3 = dark). Writing a value between 1..3 forces the backlight controller to enter the corresponding Ambient Light Zone. Writing 0 returns to normal operation. Fix valid range checking so we don't write invalid values to the controller, and make sure we subtract 1, since this is what the register definition (CFGR:BLV) requires. Otherwise the values written don't work correctly.

2010-11-12backlight: add low threshold to pwm backlightArun Murthy
The intensity of the backlight can be varied from a range of max_brightness to zero. Though most, if not all the pwm based backlight devices start flickering at lower brightness value. And also for each device there exists a brightness value below which the backlight appears to be turned off though the value is not equal to zero. If the range of brightness for a device is from zero to max_brightness. A graph is plotted for brightness Vs intensity for the pwm based backlight device has to be a linear graph. intensity | / | / | / |/ --------- 0 max_brightness But pratically on measuring the above we note that the intensity of backlight goes to zero(OFF) when the value in not zero almost nearing to zero(some x%). so the graph looks like intensity | / | / | / | | ------------ 0 x max_brightness In order to overcome this drawback knowing this x% i.e nothing but the low threshold beyond which the backlight is off and will have no effect, the brightness value is being offset by the low threshold value(retaining the linearity of the graph). Now the graph becomes intensity | / | / | / | / ------------- 0 max_brightness With this for each and every digit increment in the brightness from zero there is a change in the intensity of backlight. Devices having this behaviour can set the low threshold brightness(lth_brightness) and pass the same as platform data else can have it as zero.
