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. Signed-off-by:

Revert 7eea4364. 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.

With NO_HZ disabled, the UML idle loop effectively becomes a busy loop, as it will sleep for no time. The cause was forgetting to restart the tick after waking up from sleep. It was disabled before sleeping, and the remaining time used as the interval to sleep. So, the tick needs to be restarted when nanosleep finishes. This is done by introducing after_sleep_interval, which is empty in the NO_HZ case, but which sets the tick starting in the !NO_HZ case. Signed-off-by:

An unprivileged process must be able to kill a setuid root program started by the same user. This is legacy behavior needed for instance for xinit to kill X when the window manager exits. When an unprivileged user runs a setuid root program in !SECURE_NOROOT mode, fP, fI, and fE are set full on, so pP' and pE' are full on. Then cap_task_kill() prevents the user from signaling the setuid root task. This is a change in behavior compared to when !CONFIG_SECURITY_FILE_CAPABILITIES. This patch introduces a special check into cap_task_kill() just to check whether a non-root user is signaling a setuid root program started by the same user. If so, then signal is allowed.

This patch corrects recently changed (and now invalid) Kconfig descriptions for the DMA engine framework: - Non-Intel(R) hardware also has DMA engines; - DMA is used for more than memcpy and RAID offloading. In fact, on most platforms memcpy and RAID aren't factors, and DMA exists so that peripherals can transfer data to/from memory while the CPU does other work. Signed-off-by:

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). Signed-off-by:

People discuss how the namespaces are working/going-to-work together. Ted Ts'o proposed to create some document that describes what problems user may have when he/she creates some new namespace, but keeps others shared. I liked this idea, so here's the initial version of such a document with the problems I currently have in mind and can describe somewhat audibly - the "namespaces compatibility list". The Documentation/namespaces/ directory is about to contain more docs about the namespaces stuff. Thanks to Cedirc for notes and spell checks on the doc, to Daniel for additional info about IPC and User namespaces interaction and to Randy, who alluded me to using a spell checker before sending the documentation :) Signed-off-by:

Commit 7d69a1f4 ("remove CONFIG_UTS_NS and CONFIG_IPC_NS") by Cedric Le Goater accidentally removed the code that prevented the uts->hostname and uts->domainname values from being overwritten from another namespace. In other words, setting hostname/domainname via sysfs (echo xxx > /proc/sys/kernel/(host|domain)name) cased the new value to be set in init UTS namespace only. Return the isolation back.

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? Signed-off-by:

During the initialization of the TPM TIS driver, the necessary locality has to be requested earlier in the init-process. Depending on the used TPM chip, this leads to wrong information. For example: Lenovo X61s with Atmel TPM: tpm_tis 00:0a: 1.2 TPM (device-id 0xFFFF, rev-id 255) But correct is: tpm_tis 00:0c: 1.2 TPM (device-id 0x3203, rev-id 9) This short patch fixes this issue.

Oleg noticed that the call of task_pid_nr_ns() in proc_pid_readdir is racy with respect to tasks exiting. After a bit of examination it also appears that the call itself is completely unnecessary. So to fix the problem this patch modifies next_tgid() to return both a tgid and the task struct in question. A structure is introduced to return these values because it is slightly cleaner and easier to optimize, and the resulting code is a little shorter. Signed-off-by:

proc_kill_inodes() can clear ->i_fop in the middle of vfs_readdir resulting in NULL dereference during "file->f_op->readdir(file, buf, filler)". The solution is to remove proc_kill_inodes() completely: a) we don't have tricky modules implementing their tricky readdir hooks which could keeping this revoke from hell. b) In a situation when module is gone but PDE still alive, standard readdir will return only "." and "..", because pde->next was cleared by remove_proc_entry(). c) the race proc_kill_inode() destined to prevent is not completely fixed, just race window made smaller, because vfs_readdir() is run without sb_lock held and without file_list_lock held. Effectively, ->i_fop is cleared at random moment, which can't fix properly anything.

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. [akpm@linux-foundation.org: fix text and coding-style a bit] Signed-off-by:

_PAGE_PCD maps a page with caching disabled, which is typically used for mapping harware registers. Xen never allows it to be set on a mapping, and unprivileged guests never need it since they can't see the real underlying hardware. However, some uncached mappings are made early when probing the (non-existent) APIC, and its OK to mask off the PCD flag in these cases. This became necessary because Xen started checking for this bit, rather than silently masking it off. Signed-off-by:

Ordinarily the size of a pageblock is determined at compile-time based on the hugepage size. On PPC64, the hugepage size is determined at runtime based on what is supported by the machine. With legacy machines such as iSeries that do not support hugepages, HPAGE_SHIFT is 0. This results in pageblock_order being set to -PAGE_SHIFT and a crash results shortly afterwards. This patch adds a function to select a sensible value for pageblock order by default when HUGETLB_PAGE_SIZE_VARIABLE is set. It checks that HPAGE_SHIFT is a sensible value before using the hugepage size; if it is not MAX_ORDER-1 is used. This is a fix for 2.6.24. Credit goes to Stephen Rothwell for identifying the bug and testing candidate patches. Additional credit goes to Andy Whitcroft for spotting a problem with respects to IA-64 before releasing. Additional credit to David Gibson for testing with the libhugetlbfs test suite. Signed-off-by:

This version brings a new terse output mode as well as many improvements to the unary detection and bare type regcognition. It also brings the usual updates for false positives, though these seem to be slowing markedly now that the unary detector is no longer just putting its finger in the air and guessing. Of note: - new --terse mode producing a single line per report - loosening of the block brace checks - new checks for enum/union/struch brace placements - hugely expanded "bare type" detection - checks for inline usage - better handling of already open comment blocks - handle patches which introduce or remove lines without newlines Andy Whitcroft (19): Version: 0.12 style fixes as spotted by checkpatch add a --terse options of a single line of output per report block brace checks should only apply for single line blocks all new bare type detector check spacing for open braces with enum, union and struct check for LINUX_VERSION_CODE macros definition bracketing checks need to ignore -ve context clean up the mail-back mode, -q et al expand possible type matching to declarations allow const and sparse annotations on possible types handle possible types as regular types everywhere prefer plain inline over __inline__ and __inline all new open comment detection fix up conditional extraction for if assignment checks add const to the possible type matcher unary checks: a for loop is a conditional too possible types: detect function pointer definitions handle missind newlines at end of file, report addition Signed-off-by:Andy Whitcroft <apw@shadowen.org> Acked-by:
