SHWT value is used as address valid to -CSx assertion and -CSx to -DIOx assertion setup time, and contrarywise, -DIOx to -CSx release and -CSx release to address invalid hold time, so it actualy applies 4 times and so constitutes -DIOx recovery time. Check requirement of the recovery time and cycle time. Also check SHWT maximum value. Suggested-by:

e5318b53 ("ide: use the dma safe check for REQ_TYPE_ATA_PC") introduced a regression which caused some ATAPI drives to turn off DMA for REQ_TYPE_BLOCK_PC commands while burning and thus degrading performance and ultimately causing an excessive amount of underruns. The issue is documented also in: http://bugzilla.kernel.org/show_bug.cgi?id=11742. Signed-off-by:

There is a problem discovered in recent versions of ATI Mach64 driver in X.org on sparc64 architecture. In short, the driver fails to mmap MMIO aperture (PCI resource #2). I've found that kernel's __pci_mmap_make_offset() returns EINVAL. It checks whether user attempts to mmap more than the resource length, which is 0x1000 bytes in our case. But PAGE_SIZE on SPARC64 is 0x2000 and this is what actually is being mmaped. So __pci_mmap_make_offset() failed for this PCI resource. Signed-off-by:

We broke O_NONBLOCK handling in OSS dmasound_core in 2.3.11-pre3 - the original code copied f_flags to open_mode and then checked for O_NONBLOCK in there, but that got changed to copying f_mode and O_NONBLOCK has not reached that field in any kernel version. Since we do not care for any other bits, the fix is obvious... Signed-off-by:

Removed duplicated #include <linux/delay.h> in init/do_mounts_md.c. The same compile error ("error: implicit declaration of function 'msleep'") got fixed twice: - f8b77d39 ("init/do_mounts_md.c: msleep compile fix") - 73b4a24f ("init/do_mounts_md.c must #include <linux/delay.h>") by people adding the <linux/delay.h> include in two slightly different places. Andrew's quilt scripts happily ignore the fuzz, and will re-apply the patch even though they had conflicts. Signed-off-by:

This makes the late e820 resources use 'insert_resource_expand_to_fit()' instead of doing a 'reserve_region_with_split()', and also avoids marking them as IORESOURCE_BUSY. This results in us being perfectly happy to use pre-existing PCI resources even if they were marked as being in a reserved region, while still avoiding any _new_ allocations in the reserved regions. It also makes for a simpler and more accurate resource tree. Example resource allocation from Jonathan Corbet, who has firmware that has an e820 reserved entry that covered a big range (e0000000-fed003ff), and that had various PCI resources in it set up by firmware. With old kernels, the reserved range would force us to re-allocate all pre-existing PCI resources, and his reserved range would end up looking like this: e0000000-fed003ff : reserved fec00000-fec00fff : IOAPIC 0 fed00000-fed003ff : HPET 0 where only the pre-allocated special regions (IOAPIC and HPET) were kept around. With 2.6.28-rc2, which uses 'reserve_region_with_split()', Jonathan's resource tree looked like this: e0000000-fe7fffff : reserved fe800000-fe8fffff : PCI Bus 0000:01 fe800000-fe8fffff : reserved fe900000-fe9d9aff : reserved fe9d9b00-fe9d9bff : 0000:00:1f.3 fe9d9b00-fe9d9bff : reserved fe9d9c00-fe9d9fff : 0000:00:1a.7 fe9d9c00-fe9d9fff : reserved fe9da000-fe9dafff : 0000:00:03.3 fe9da000-fe9dafff : reserved fe9db000-fe9dbfff : 0000:00:19.0 fe9db000-fe9dbfff : reserved fe9dc000-fe9dffff : 0000:00:1b.0 fe9dc000-fe9dffff : reserved fe9e0000-fe9fffff : 0000:00:19.0 fe9e0000-fe9fffff : reserved fea00000-fea7ffff : 0000:00:02.0 fea00000-fea7ffff : reserved fea80000-feafffff : 0000:00:02.1 fea80000-feafffff : reserved feb00000-febfffff : 0000:00:02.0 feb00000-febfffff : reserved fec00000-fed003ff : reserved fec00000-fec00fff : IOAPIC 0 fed00000-fed003ff : HPET 0 and because the reserved entry had been split and moved into the individual resources, and because it used the IORESOURCE_BUSY flag, the drivers that actually wanted to _use_ those resources couldn't actually attach to them: e1000e 0000:00:19.0: BAR 0: can't reserve mem region [0xfe9e0000-0xfe9fffff] HDA Intel 0000:00:1b.0: BAR 0: can't reserve mem region [0xfe9dc000-0xfe9dffff] with this patch, the resource tree instead becomes e0000000-fed003ff : reserved fe800000-fe8fffff : PCI Bus 0000:01 fe9d9b00-fe9d9bff : 0000:00:1f.3 fe9d9c00-fe9d9fff : 0000:00:1a.7 fe9d9c00-fe9d9fff : ehci_hcd fe9da000-fe9dafff : 0000:00:03.3 fe9db000-fe9dbfff : 0000:00:19.0 fe9db000-fe9dbfff : e1000e fe9dc000-fe9dffff : 0000:00:1b.0 fe9dc000-fe9dffff : ICH HD audio fe9e0000-fe9fffff : 0000:00:19.0 fe9e0000-fe9fffff : e1000e fea00000-fea7ffff : 0000:00:02.0 fea80000-feafffff : 0000:00:02.1 feb00000-febfffff : 0000:00:02.0 fec00000-fec00fff : IOAPIC 0 fed00000-fed003ff : HPET 0 ie the one reserved region now ends up surrounding all the PCI resources that were allocated inside of it by firmware, and because it is not marked BUSY, drivers have no problem attaching to the pre-allocated resources.

This one apparently doesn't generate any warnings, because the function is only used during system bootup, when the warnings are disabled. But it's still very wrong. The __reserve_region_with_split() function is called with the resource_lock held for writing, so it must only ever do GFP_ATOMIC allocations. Signed-off-by:

As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore. Signed-off-by:

While Linux doesn't honor setuid on scripts. However, it mistakenly behaves differently for file capabilities. This patch fixes that behavior by making sure that get_file_caps() begins with empty bprm->caps_*. That way when a script is loaded, its bprm->caps_* may be filled when binfmt_misc calls prepare_binprm(), but they will be cleared again when binfmt_elf calls prepare_binprm() next to read the interpreter's file capabilities.

SELinux has wrongly (since 2004) had an incorrect test for an empty tty->tty_files list. With an empty list selinux would be pointing to part of the tty struct itself and would then proceed to dereference that value and again dereference that result. An F10 change to plymouth on a ppc64 system is actually currently triggering this bug. This patch uses list_empty() to handle empty lists rather than looking at a meaningless location.

Remove the links to architecture and machine dependent directories (boot, lib, drivers, arch, mach) The links were created and used mostly from the arch/cris/Makefile, so why not dispense with them altogether? Changed $(ARCH) to "cris" in Makefile, it is easier to read this way. The CRISv32 head.S common files for the kernel and compressed images needed to be modified to use ifdefs instead of using the now removed mach link. Since there are only two versions, this is not a huge loss in readability. The link to vmlinux.lds.S is also replaced with a merged version which uses ifdefs to select the correct layout. System.map before and after are identical. Signed-off-by:
