From: William Lee Irwin III <wli@holomorphy.com> start_jiffies was not respected by set_timeout(), which reread jiffies instead of respecting what read_events() passed it. This difference can be significant, particularly if the calling process slept during the copy_to_user() operation in read_events(). To correct this, this patch teaches it to respect its argument, with the additional bonus of converting it to use timespec_to_jiffies() instead of open-coding it. Signed-off-by:

From: William Lee Irwin III <wli@holomorphy.com> The time conversion functions may have const args, which is in fact useful for when they are passed const variables as arguments so as to avoid discarding qualifiers from pointer types warnings. This is a preparatory cleanup for a minor aio bugfix. Signed-off-by:

From: Russell King <rmk+lkml@arm.linux.org.uk> It appears the loop driver has had one flush_dcache_page() call added for the case where it writes to the backing device page cache pages. However, it seems to be missing the call where it writes to its own page cache pages. Signed-off-by:

From: Jack Steiner <steiner@sgi.com> It looks like the call to sched_balance_exec() from do_execve() is in the wrong spot. The code calls sched_balance_exec() before determining whether "filename" actually exists. In many cases, users have several entries in $PATH. If a full path name is not specified on the 'exec" call, the library code iterates thru the files in the PATH list until it finds the program. This can result is numerous migrations of the parent process before the program is actually found. Signed-off-by:

`make buildcheck' only checks for calls to linker discarded sections, reference_init checks for calls to sections discarded at run time, init was cloned from discarded. They are separate because the linker detects the discarded case and I did not want to confuse users with messages about init text/data while they were fixing the linker errors. Signed-off-by:

From: Andries Brouwer <Andries.Brouwer@cwi.nl> The patch examines a putative partition table, and if that doesnt look like a valid partition table it goes away again. Some devices have partition tables (and there are many styles of such), some don't. Traditionally fixed disks have one, floppies don't. Nobody knows what happens with ZIP disks, USB sticks and other such things. Both the DOS-type partition table, and the "big floppy" whole disk FAT filesystem are common. It is undesirable for the kernel to detect partitions where there are none. This leads to great confusion, sometimes to kernel crashes. In the particular case of DOS-type partition tables a partition entry has a 1-byte field boot_ind that traditionally is 0x80 for the boot partition and 0 for the other three primary partitions. Linux does not use this field, and one sometimes sees tables with all four entries zero. The patch tells the kernel not to think that something is a valid DOS-type partition table when a value other than 0 or 0x80 is encountered. I think it is a fairly safe change: I do not know of any fdisk-type program that will write other values there. Signed-off-by:

From: Nathan Lynch <nathanl@austin.ibm.com> On some systems it can take a hotplugged cpu much longer to come up than it would at boot. If the cpu comes up after we've given up on it, it tends to die in its first attempt to kmem_cache_alloc (uninitialized percpu data, I imagine). In my experimentation I haven't seen a processor take more than one second to become available; the patch waits five seconds just to be safe. Signed-off-by:

From: Olaf Hering <olh@suse.de> /proc/iSeries/config contains now the number of configured virtual ethernet adapters. AVAILABLE_VETH should only indicate if there is at least one interface available, iseries_veth must be loaded in this case. Printing the entire map will give installers some hints about what interface numbers will appear and how the MAC address may look like. Signed-off-by:

From: Matt Porter <mporter@kernel.crashing.org> DCR number is encoded in mfdcr/mtdcr command itself and this prevents easy DCR access when register number is not known on compile time. This patch adds __mfdcr & __mtdcr helpers which use pre-generated mfdcr/mtdcr sequences for all possible DCR numbers. We also use GCC extension __builtin_constant_p to optimize cases when DCR number is in fact known during compilation. Signed-off-by:

- Off-by-one in balance_pgdat means that we're not scanning the zones all the way down to priority=0. - Always set zone->temp_priority in shrink_caches(). I'm not sure why I had the `if (zone->free_pages < zone->pages_high)' test in there, but it's preventing us from setting ->prev_priority correctly on the try_to_free_pages() path. - Set zone->prev_priority to the current priority if it's currently a "lower" priority. This allows us to build up the pressure on mapped pages on the first scanning pass rather than only on successive passes. Signed-off-by:

Writing to ramfs files with O_SYNC dereferences null in mpage_writepages(), due to null a_ops->writepage. The call path is generic_file_aio_write_nolock ->generic_osync_inode ->write_inode_now ->__writeback_single_inode ->__sync_single_inode ->do_writepages ->mpage_writepages The best fix for this is to visit all ram-backed filesystems and give them a no-op a_ops.writepages. But baling out if the file is memory-backed is a sufficient coverall and is how we handle this in __filemap_fdatawrite(). Signed-off-by:

When taskfile delivery is improved, we will actually perform this command, instead of no-oping it. For now, this is cosmetic except for removing an annoying message that some users see.

Jeff Garzik authored
The ->tf_load and ->exec_command driver hooks were changed to assume that PIO was the only type of taskfile ever delivered to these functions. This will be true... in the future, but not today. In other drivers this change was not needed, but Promise executes commands differently due to its "ATA packet" hardware features, so the Promise drivers need this change reverted.

The attached patch updates generic HDLC: - fixed some carrier-related problems (Cisco HDLC and FR links could report valid link when no carrier was detected at startup). - fixed kbuild problems with wanxl firmware (building kernel in separate tree). $(src)/wanxlfw.inc is now wanxlfw.inc_shipped.

Revert CONFIG_NET_GIGE change. The proper fix is _not_ NET_ETHERNET or default twiddling, but better overall organization of the ethernet driver selection, which would include not only CONFIG_NET_GIGE but other options as well. Reverted back to old behavior until a full and complete solution appears (and people like it, of course).
