2007-12-14fb_ddc: fix DDC lines quirkJean Delvare
patch b64d70825abbf706bbe80be1b11b09514b71f45e in mainline. 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?

2007-12-14PNP: increase the maximum number of resourcesZhao Yakui
patch a7839e960675b549f06209d18283d5cee2ce9261 in mainline. On some systems the number of resources(IO,MEM) returnedy by PNP device is greater than the PNP constant, for example motherboard devices. It brings that some resources can't be reserved and resource confilicts. This will cause PCI resources are assigned wrongly in some systems, and cause hang. This is a regression since we deleted ACPI motherboard driver and use PNP system driver.

patch cb43c54ca05c01533c45e4d3abfe8f99b7acf624 in mainline.

patch 0967b7bf1c22b55777aba46ff616547feed0b141 in mainline.

commit 5d0360ee96a5ef953dbea45873c2a8c87e77d59b upstream. We have seen ramdisk based install systems, where some pages of mapped libraries and programs were suddendly zeroed under memory pressure. This should not happen, as the ramdisk avoids freeing its pages by keeping them dirty all the time. It turns out that there is a case, where the VM makes a ramdisk page clean, without telling the ramdisk driver. On memory pressure shrink_zone runs and it starts to run shrink_active_list. There is a check for buffer_heads_over_limit, and if true, pagevec_strip is called. pagevec_strip calls try_to_release_page. If the mapping has no releasepage callback, try_to_free_buffers is called. try_to_free_buffers has now a special logic for some file systems to make a dirty page clean, if all buffers are clean. Thats what happened in our test case. The simplest solution is to provide a noop-releasepage callback for the ramdisk driver. This avoids try_to_free_buffers for ramdisk pages.

patch 0b5316769774d1dc2fdd702e095f9e6992af269a in mainline. ipw2200 makes extensive use of background scanning when unassociated or down. Unfortunately, the firmware sends scan completed events many times per second, which the driver pushes directly up to userspace. This needlessly wakes up processes listening for wireless events many times per second. Batch together scan completed events for non-user-requested scans and send them up to userspace every 4 seconds. Scan completed events resulting from an SIOCSIWSCAN call are pushed up without delay.

2007-11-26i2c/eeprom: Hide Sony Vaio serial numbersJean Delvare
patch 0f2cbd38aa377e30df3b7602abed69464d1970aa in mainline. The sysfs interface to DMI data takes care to not make the system serial number and UUID world-readable, presumably due to privacy concerns. For consistency, we should not let the eeprom driver export these same strings to the world on Sony Vaio laptops. Instead, only make them readable by root, as we already do for BIOS passwords.

2007-11-26i2c/eeprom: Recognize VGN as a valid Sony Vaio name prefixJean Delvare
patch 8b925a3dd8a4d7451092cb9aa11da727ba69e0f0 in mainline. Recent (i.e. 2005 and later) Sony Vaio laptops have names beginning with VGN rather than PCG. Update the eeprom driver so that it recognizes these. Why this matters: the eeprom driver hides private data from the EEPROMs it recognizes as Vaio EEPROMs (passwords, serial number...) so if the driver fails to recognize a Vaio EEPROM as such, the private data is exposed to the world.

patch be8a1f7cd4501c3b4b32543577a33aee6d2193ac in mainline. Turns out we don't actually check the status to see if there was a device out there to talk to, just if we had a timeout when doing so. Add the proper check, so we don't falsly think there are devices on the bus that are not there, etc. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-11-16libata: backport ATA_FLAG_NO_SRST and ATA_FLAG_ASSUME_ATA, part 2Tejun Heo
Differs from mainline, but the functionality is already there. P5W-DH Deluxe has ICH7R which doesn't have PMP support but SIMG 4726 hardwired to the second port of AHCI controller at PCI device 1f.2. The 4726 doesn't work as PMP but as a storage processor which can do hardware RAID on downstream ports. When no device is attached to the downstream port of the 4726, pseudo ATA device for configuration appears. Unfortunately, ATA emulation on the device is very lousy and causes long hang during boot. This patch implements workaround for the board. If the mainboard is P5W-DH Deluxe (matched using DMI), only hardreset is used on the second port of AHCI controller @ 1f.2 and the hardreset doesn't depend on receiving the first FIS and just proceed to IDENTIFY. This workaround fixes bugzilla #8923. http://bugzilla.kernel.org/show_bug.cgi?id=8923 Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Jeff Garzik <jeff@garzik.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Differs from mainline, but the functionality is already there. Backport ATA_FLAG_NO_SRST and ATA_FLAG_ASSUME_ATA. These are originally link flags (ATA_LFLAG_*) but link abstraction doesn't exist on 2.6.23, so make it port flags. This is for the following workaround for ASUS P5W DH Deluxe. These new flags don't introduce any behavior change unless set and nobody sets them yet.
