This is a reimplemention of commit 0119509c from Matthew Garrett <mjg59@srcf.ucam.org> This patch got removed because of a regression: ThinkPads with a Intel graphics card and an Integrated Graphics Device BIOS implementation stopped working. In fact, they only worked because the ACPI device of the discrete, the wrong one, got used (via int10). So ACPI functions were poking on the wrong hardware used which is a sever bug. The next patch provides support for above ThinkPads to be able to switch brightness via the legacy thinkpad_acpi driver and automatically detect when to use it. Original commit message from Matthew Garrett: Vendors often ship machines with a choice of integrated or discrete graphics, and use the same DSDT for both. As a result, the ACPI video module will locate devices that may not exist on this specific platform. Attempt to determine whether the device exists or not, and abort the device creation if it doesn't. http://bugzilla.kernel.org/show_bug.cgi?id=9614Signed-off-by: NThomas Renninger <trenn@suse.de> Acked-by: NZhang Rui <rui.zhang@intel.com> Signed-off-by: NAndi Kleen <ak@linux.intel.com> Signed-off-by: NLen Brown <len.brown@intel.com>

IA64 kdump kernel failed to initialize /proc/vmcore in 2.6.28-rc2. A bug was introduced in this patch commit: d9a9855d always reserve elfcore header memory in crash kernel The problem was that the call to reserve_elfcorehdr() should be placed in CONFIG_CRASH_DUMP rather than in CONFIG_CRASH_KERNEL, which does not exist.

When initializing an uninitialized block group in ext4_new_inode(), its block group checksum must be re-calculated. This fixes a race when several threads try to allocate a new inode in an UNINIT'd group. There is some question whether we need to be initializing the block bitmap in ext4_new_inode() at all, but for now, if we are going to init the block group, let's eliminate the race.

Xen requires that all mappings of pagetable pages are read-only, so that they can't be updated illegally. As a result, if a page is being turned into a pagetable page, we need to make sure all its mappings are RO. If the page had been used for ioremap or vmalloc, it may still have left over mappings as a result of not having been lazily unmapped. This change makes sure we explicitly mop them all up before pinning the page. Unlike aliases created by kmap, the there can be vmalloc aliases even for non-high pages, so we must do the flush unconditionally.

__scm_destroy() walks the list of file descriptors in the scm_fp_list pointed to by the scm_cookie argument. Those, in turn, can close sockets and invoke __scm_destroy() again. There is nothing which limits how deeply this can occur. The idea for how to fix this is from Linus. Basically, we do all of the fput()s at the top level by collecting all of the scm_fp_list objects hit by an fput(). Inside of the initial __scm_destroy() we keep running the list until it is empty.

Fix the hrtimer_add_expires_ns() function. It should take a 'u64 ns' argument, but rather takes an 'unsigned long ns' argument - which might only be 32-bits. On FRV, this results in the kernel locking up because hrtimer_forward() passes the result of a 64-bit multiplication to this function, for which the compiler discards the top 32-bits - something that didn't happen when ktime_add_ns() was called directly.

FAT has the ATTR_RO (read-only) attribute. But on Windows, the ATTR_RO of the directory will be just ignored actually, and is used by only applications as flag. E.g. it's setted for the customized folder by Explorer. http://msdn2.microsoft.com/en-us/library/aa969337.aspx This adds "rodir" option. If user specified it, ATTR_RO is used as read-only flag even if it's the directory. Otherwise, inode->i_mode is not used to hold ATTR_RO (i.e. fat_mode_can_save_ro() returns 0).

If inode->i_mode doesn't have S_WUGO, current code assumes it means ATTR_RO. However, if (~[ufd]mask & S_WUGO) == 0, inode->i_mode can't hold S_WUGO. Therefore the updated directory entry will always have ATTR_RO. This adds fat_mode_can_hold_ro() to check it. And if inode->i_mode can't hold, uses -i_attrs to hold ATTR_RO instead. With this, we don't set ATTR_RO unless users change it via ioctl() if (~[ufd]mask & S_WUGO) == 0. And on FAT_IOCTL_GET_ATTRIBUTES path, this adds ->i_mutex to it for not returning the partially updated attributes by FAT_IOCTL_SET_ATTRIBUTES to userland.
