2007-12-01net: smc911x: only enable for mpr2 on sh.Paul Mundt
The smc911x.h is a bit of a mess, not supporting any sort of generic configuration. For the moment only ARCH_PXA and SH_MAGIC_PANEL_R2 have suitable definitions, so we reflect this in the Kconfig also. While there are other SH boards that will likely turn this on in the 2.6.25 time frame, it's not worth trying to stub around at the moment. Fixes up the allmodconfig build, as noted by akpm.

2007-12-01sky2: don't use AER routinesStephen Hemminger
Using PCIE advanced error recovery stuff creates more user problems than it's worth. The AER stuff depends on MMCONFIG and in many configurations it just doesn't work. Plus it doesn't add any real functionality to the driver. The sky2 driver handles its own errors fine as is.

2007-11-29ACPI: avoid references to impossible processors.Christoph Lameter
ACPI uses NR_CPUS in various loops and in some it accesses per cpu data of processors that are not present(!) and that will never be present. The pointers to per cpu data are typically not initialized for processors that are not present. So we seem to be reading something here from offset 0 in memory. Make ACPI use nr_cpu_ids instead. That stops at the end of the possible processors. Convert one loop to NR_CPUS to use the cpu_possible map instead. That way ranges of processor that can never be brought online are skipped during the loop.

2007-11-29x86_64 EFI boot support: EFI frame buffer driverHuang, Ying
This patch adds Graphics Output Protocol support to the kernel. UEFI2.0 spec deprecates Universal Graphics Adapter (UGA) protocol and only Graphics Output Protocol (GOP) is produced. Therefore, the boot loader needs to query the UEFI firmware with appropriate Output Protocol and pass the video information to the kernel. As a result of GOP protocol, an EFI framebuffer driver is needed for displaying console messages. The patch adds a EFI framebuffer driver. The EFI frame buffer driver in this patch is based on the Intel Mac framebuffer driver. The ELILO bootloader takes care of passing the video information as appropriate for EFI firmware. The framebuffer driver has been tested in i386 kernel and x86_64 kernel on EFI platform.

2007-11-29revert "keyspan: init termios properly"Andrew Morton
Revert 7eea436433b7b18045f272562e256976f593f7c0. Lucy said: This patch will work with the 19HS but WILL BREAK all other Keyspan adapters. It will take me a few days to get to looking at a correct fix but that keyspan_send_setup(port, 1) (and the '1' is the important part) must happen once when the port is first opened. The cflag can just be set to whatever the normal default is for your serial environment. So revert this again pending the proper fix.

This patch adds an additional loop, that delays turning off the DMA until the LCDC core has been turned off. This prevents the picture to be shifted some random length when the kernel re-initializes the LCDC. Without this patch, the LCDC keeps running for some small time after the PWRCON:LCD_PWR has been cleared ; the FIFO suffers an underrun and on re-starting the LCDC the FIFO data stays shifted. This behavior has been seen and fixed on AT91SAM9261-EK and two custom AT91SAM9261 boards, all of them having different LCD panels. Thanks a lot to Anti Sullin for submitting this patch (long time ago).

2007-11-29drivers/pnp/resource.c: Add missing pci_dev_putJulia Lawall
There should be a pci_dev_put when breaking out of a loop that iterates over calls to pci_get_device and similar functions. This was fixed using the following semantic patch. // <smpl> @@ identifier d; type T; expression e; iterator for_each_pci_dev; @@ T *d; ... for_each_pci_dev(d) {... when != pci_dev_put(d) when != e = d ( return d; | + pci_dev_put(d); ? return ...; ) ...} // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Greg KH <greg@kroah.com> Cc: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-11-29fb_ddc: fix DDC lines quirkJean Delvare
The code in fb_ddc_read() is said to be based on the implementation of the radeon driver: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=fc5891c8a3ba284f13994d7bc1f1bfa8283982de However, comparing the old radeon driver code with the new fb_ddc code reveals some differences. Most notably, the I2C bus lines are held at the end of the function, while the original code was releasing them (as the comment above correctly says.) There are a few other differences, which appear to be responsible for read failures on my system. While tracing low-level I2C code in i2c-algo-bit, I noticed that the initial attempt to read the EDID always failed. It takes one retry for the read to succeed. As we are about to remove this automatic retry property from i2c-algo-bit, reading the EDID would really fail. As a summary, the I2C lines quirk which is supposedly needed to read EDID on some older monitors is currently breaking the (first) read on all other monitors (and might not even work with older ones - did anyone try since October 2006?) After applying the patch below, which makes the code in fb_ddc_read() really similar to what the radeon driver used to have, the first EDID read succeeds again. On top of that, as it appears that this code has been broken for one year now and nobody seems to have complained, I'm curious if it makes sense to keep this quirk in place. It makes the code more complex and slower just for the sake of monitors which I guess nobody uses anymore. Can't we just get rid of it?
