2009-03-30cpumask: use set_cpu_active in init/main.cRusty Russell
cpu_active_map is deprecated in favor of cpu_active_mask, which is const for safety: we use accessors now (set_cpu_active) is we really want to make a change. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-03-30cpumask: remove dangerous CPU_MASK_ALL_PTR, &CPU_MASK_ALLRusty Russell
Impact: cleanup (Thanks to Al Viro for reminding me of this, via Ingo) CPU_MASK_ALL is the (deprecated) "all bits set" cpumask, defined as so: #define CPU_MASK_ALL (cpumask_t) { { ... } } Taking the address of such a temporary is questionable at best, unfortunately 321a8e9d (cpumask: add CPU_MASK_ALL_PTR macro) added CPU_MASK_ALL_PTR: #define CPU_MASK_ALL_PTR (&CPU_MASK_ALL) Which formalizes this practice. One day gcc could bite us over this usage (though we seem to have gotten away with it so far). So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR with the modern "cpu_all_mask" (a real const struct cpumask *).

2009-03-28fastboot: remove duplicate unpack_to_rootfs()Li, Shaohua
we check if initrd is initramfs first and then do the real unpack. The check isn't required, we can directly do unpack. If the initrd isn't an initramfs, we can remove the garbage. In my laptop, this saves 0.1s boot time. This patch penalizes non-initramfs initrd case, but nowadays, initramfs is the most widely used method for initrds.

This reverts commit 155b25bcc28631a5b5230191aa3f56c40dfffa3f, which was totally wrong - the "embedded" options still exists (very much so) even on non-embedded platforms. It's just that we don't bother with actually asking about them when we're not embedded, we just take their default values (which is usually 'y' - the options add features that may not be worth it in a constrained environment).

2009-02-26rcu: Teach RCU that idle task is not quiscent state at bootPaul E. McKenney
This patch fixes a bug located by Vegard Nossum with the aid of kmemcheck, updated based on review comments from Nick Piggin, Ingo Molnar, and Andrew Morton. And cleans up the variable-name and function-name language. ;-) The boot CPU runs in the context of its idle thread during boot-up. During this time, idle_cpu(0) will always return nonzero, which will fool Classic and Hierarchical RCU into deciding that a large chunk of the boot-up sequence is a big long quiescent state. This in turn causes RCU to prematurely end grace periods during this time. This patch changes the rcutree.c and rcuclassic.c rcu_check_callbacks() function to ignore the idle task as a quiescent state until the system has started up the scheduler in rest_init(), introducing a new non-API function rcu_idle_now_means_idle() to inform RCU of this transition. RCU maintains an internal rcu_idle_cpu_truthful variable to track this state, which is then used by rcu_check_callback() to determine if it should believe idle_cpu(). Because this patch has the effect of disallowing RCU grace periods during long stretches of the boot-up sequence, this patch also introduces Josh Triplett's UP-only optimization that makes synchronize_rcu() be a no-op if num_online_cpus() returns 1. This allows boot-time code that calls synchronize_rcu() to proceed normally. Note, however, that RCU callbacks registered by call_rcu() will likely queue up until later in the boot sequence. Although rcuclassic and rcutree can also use this same optimization after boot completes, rcupreempt must restrict its use of this optimization to the portion of the boot sequence before the scheduler starts up, given that an rcupreempt RCU read-side critical section may be preeempted. In addition, this patch takes Nick Piggin's suggestion to make the system_state global variable be __read_mostly. Changes since v4: o Changes the name of the introduced function and variable to be less emotional. ;-) Changes since v3: o WARN_ON(nr_context_switches() > 0) to verify that RCU switches out of boot-time mode before the first context switch, as suggested by Nick Piggin. Changes since v2: o Created rcu_blocking_is_gp() internal-to-RCU API that determines whether a call to synchronize_rcu() is itself a grace period. o The definition of rcu_blocking_is_gp() for rcuclassic and rcutree checks to see if but a single CPU is online. o The definition of rcu_blocking_is_gp() for rcupreempt checks to see both if but a single CPU is online and if the system is still in early boot. This allows rcupreempt to again work correctly if running on a single CPU after booting is complete. o Added check to rcupreempt's synchronize_sched() for there being but one online CPU. Tested all three variants both SMP and !SMP, booted fine, passed a short rcutorture test on both x86 and Power.

2009-01-14init: make initrd/initramfs decompression failure a KERN_EMERG eventH. Peter Anvin
Impact: More consistent behaviour, avoid policy in the kernel Upgrade/downgrade initrd/initramfs decompression failure from inconsistently a panic or a KERN_ALERT message to a KERN_EMERG event. It is, however, possible do design a system which can recover from this (using the kernel builtin code and/or the internal initramfs), which means this is policy, not a technical necessity. A good way to handle this would be to have a panic-level=X option, to force a panic on a printk above a certain level. That is a separate patch, however. Signed-off-by: H.

2009-01-08NOMMU: Support XIP on initramfsDavid Howells
Support XIP on files unpacked from the initramfs image on NOMMU systems. This simply requires the length of the file to be preset so that the ramfs fs can attempt to garner sufficient contiguous storage to store the file (NOMMU mmap can only map contiguous RAM). All the other bits to do XIP on initramfs files are present: (1) ramfs's truncate attempts to allocate a contiguous run of pages when a file is truncated upwards from nothing. (2) ramfs sets BDI on its files to indicate direct mapping is possible, and that its files can be mapped for read, write and exec. (3) NOMMU mmap() will use the above bits to determine that it can do XIP. Possibly this needs better controls, because it will _always_ try and do XIP. One disadvantage of this very simplistic approach is that sufficient space will be allocated to store the whole file, and not just the bit that would be XIP'd. To deal with this, though, the initramfs unpacker would have to be able to parse the file contents. Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Paul Mundt <lethal@linux-sh.org>

2009-01-07async: Asynchronous function calls to speed up kernel bootArjan van de Ven
Right now, most of the kernel boot is strictly synchronous, such that various hardware delays are done sequentially. In order to make the kernel boot faster, this patch introduces infrastructure to allow doing some of the initialization steps asynchronously, which will hide significant portions of the hardware delays in practice. In order to not change device order and other similar observables, this patch does NOT do full parallel initialization. Rather, it operates more in the way an out of order CPU does; the work may be done out of order and asynchronous, but the observable effects (instruction retiring for the CPU) are still done in the original sequence.

It also removes a couple of warnings which occur when no ramdisk compression at all is chosen. It also restores the select ZLIB_INFLATE in drivers/block/Kconfig which somehow came missing.

2009-01-06do_mounts: add device info to mount messageMarton Balint
In the past, I used the root=... command line parameter to specify the root filesystem to the kernel. Now it seems that specifying it is not necessary. The kernel detects the root filesystem even if the kernel command line is empty. My root fs is on a raid1 device by the way, and I am not using initrd for the boot process. If the kernel detects the root filesystem somehow, I think it should print out the result of this detection, otherwise I will not know which device has the root filesystem. Or is there an easy way to get this information on a running system? I had a quick look at the /proc and /sys filesystems, but haven't found anything useful there.

2009-01-06init: properly placing noinline keywordRakib Mullick
checkpatch warns about 'static void noinline'. It wants `static noinline void'. Both are permissible, but the kernel consistently uses `static inline' and `static noinline', and consistency is good. Hence let's keep the checkpatch warning and fix up this code site. [akpm@linux-foundation.org: rewrote changelog] Signed-off-by: Md.Rakib H.
