Enable the reservation code by default. So reservations default to "on". They can be disabled by mounting with the "noreservation" mount option. Signed-off-by:

rbtree implementation and other changes From: Stephen Tweedie <sct@redhat.com> contributions From: Badari Pulavarty <pbadari@us.ibm.com> and probably me. This is the ext3 block reservation patch. It improves the layout of ext3 files by establishing, for each inode, reserved areas of the disk in which only that file can allocate blocks. Those reserved areas are managed in an rbtree, via the in-core inode. It's a bit like ext2 preallocation only stronger in that it can span already-allocated blocks, including the per-blockgroup inode tables and bitmaps. The patch fixes ext3's worst performance problem: disastrous layout when multiple files are being concurrently grown. It increases the size of the inode by rather a lot. A todo item is to dynamically allocate the `struct reserve_window_node', so we don't need to carry this storage for inodes which aren't opened for writing. The feature is enabled by mounting with the "reservation" mount option. Reservations default to "off". Signed-off-by:

While changing the TTY layer, an API parameter was removed, so it was removed by almost all calls, changing their prototype. But one use of one such function was not updated, breaking UML compilation. This is the fix. Signed-off-by:

This patch fixes a typo of arch/m32r/lib/delay.c. It is required to fix a compile error for non-CONFIG_ISA_DUAL_ISSUE configuration. NOTE: The m32r has a kind of ISA (instruction set architecture) like a 2-way VLIW. Originally the m32r has two types of 16-bit/32-bit instructions. Only 16-bit instruction pair can be executed in parallel on a m32r chip with dual issuing support (e.g. M32700). According to the insturction dual issuing of the m32r, a programmer/compiler can explicitly put two 16-bit instructions into an instruction word, which are to be executed in parallel. ex. Assembly coding style of two 16-bit instruncions; insn A and B: 1) insn A insn B ; sequential execution (implicit) 2) insn A -> insn B ; sequential execution (explicit) 3) insn A || insn B ; parallel execution Signed-off-by:Hirokazu Takata <takata@linux-m32r.org> Signed-off-by:

genapic broke early safe_smp_processor_id(), especially when you got a WARN_ON or oops early it would loops forever in show_trace. The reason was that the x86_cpu_to_apicid array wasn't correctly initialized. This patch fixes this by just testing for this case.

Nathan Lynch pointed this out: The CPU sibling map is never initialized on iSeries. This makes the scheduler very unhappy if CONFIG_SCHED_SMT is enabled, causing an oops in find_busiest_group during boot. Below patch adds the expected init. Signed-off-by:

Tom's recent irq patch broke PowerMac (and possibly others). I think he forgot that PReP, CHRP and PowerMac are all built together in a single kernel image, thus all of those arch_initcall's will end up beeing called, even on the wrong machine... Signed-off-by:

The data structures which are set up by key_init() are used by exec(). And we're using exec() super-early via the hotplug events from do_basic_setup():driver_init().

This merges two files (iSeries_IoMmTable.[ch]) into iSeries_pci.c. This allowed quite a few more things to become declared static. It then does some fairly mechanical cleanups in iSeries_pci.c (replacing studly caps, removing the last of the PCIFR() macros and removing a couple of empty or unused routines). There are no semantic changes. Signed-off-by:

The "Synchronize Arbitration IDs with APIC IDs" IPI does not make sense on Pentium 4 and Xeon because they don't have an APIC bus where arbitration IDs would be needed. The Intel Developers manual (Vol. 3, Ch. 8.6.1) says this IPI is unsupported on P4/Xeon. Using it may, according to Intel, lead to unpredictable results. Signed-off-by:

Early calls to userspace can invoke an execve() before any binfmt handlers are registered. Properly return an error in this case rather than 0. On at least one arch (x86_64) without this patch, the system will double fault on early attempts to call_usermodehelper. Signed-off-by:

There are two issues with online io scheduler switching that this patch addresses. The first is pretty simple - it concerns racing with scheduler removal on switch. elevator_find() does not grab a reference to the io scheduler, so before elevator_attach() is run it could go away. Add elevator_get() to solve that. Second issue is the flushing out of requests that is needed before switching can be problematic with requests that aren't allocated in the block layer (such as requests on the stack of a process). The problem is that we don't know when they will have finished, and most io schedulers need to access the elevator structures on io completion. This can be fixed by adding an intermedia step that switches to noop, since it doesn't need to touch anything but the request_queue. The queue drain can then safely be split into two operations - one that waits for file system requests, and one that waits for the queue to completely empty. Requests arriving after the first drain will get stuck in a seperate queue list. Signed-off-by:

register_sysctl_table() fails if sysctl support is not compiled into the kernel. The POSIX message queue subsystem aborted it's initialization if register_sysctl_table() fails, and that causes an oops in sys_mq_open().
