Remove is_in_rom() function. It doesn't actually serve the purpose it was intended to. If you look at the use of it _access_ok() (which is the only use of it) then it is obvious that most of memory is marked as access_ok. No point having is_in_rom() then, so remove it.

The fix to that race in alloc_fresh_huge_page() which could give an illegal node ID did not need nid_lock at all: the fix was to replace static int nid by static int prev_nid and do the work on local int nid. nid_lock did make sure that racers strictly roundrobin the nodes, but that's not something we need to enforce strictly.

I've noticed lots of failures of vmalloc_32 on machines where it shouldn't have failed unless it was doing an atomic operation. Looking closely, I noticed that: #if defined(CONFIG_64BIT) && defined(CONFIG_ZONE_DMA32) #define GFP_VMALLOC32 GFP_DMA32 #elif defined(CONFIG_64BIT) && defined(CONFIG_ZONE_DMA) #define GFP_VMALLOC32 GFP_DMA #else #define GFP_VMALLOC32 GFP_KERNEL #endif Which seems to be incorrect, it should always -or- in the DMA flags on top of GFP_KERNEL, thus this patch.

Work around a possible bug in the FRV compiler. What appears to be happening is that gcc resolves the __builtin_constant_p() in kmalloc() to true, but then fails to reduce the therefore constant conditions in the if-statements it guards to constant results. When compiling with -O2 or -Os, one single spurious error crops up in cpuup_callback() in mm/slab.c. This can be avoided by making the memsize variable const.

__acquire | lock _____ | \ | __contended | | | wait | _______/ |/ | __acquired | __release | unlock We measure acquisition and contention bouncing. This is done by recording a cpu stamp in each lock instance. Contention bouncing requires the cpu stamp to be set on acquisition. Hence we move __acquired into the generic path. __acquired is then used to measure acquisition bouncing by comparing the current cpu with the old stamp before replacing it. __contended is used to measure contention bouncing (only useful for preemptable locks) [akpm@linux-foundation.org: cleanups] Signed-off-by: NPeter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: NIngo Molnar <mingo@elte.hu> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Introduce the core lock statistics code. Lock statistics provides lock wait-time and hold-time (as well as the count of corresponding contention and acquisitions events). Also, the first few call-sites that encounter contention are tracked. Lock wait-time is the time spent waiting on the lock. This provides insight into the locking scheme, that is, a heavily contended lock is indicative of a too coarse locking scheme. Lock hold-time is the duration the lock was held, this provides a reference for the wait-time numbers, so they can be put into perspective. 1) lock 2) ... do stuff .. unlock 3) The time between 1 and 2 is the wait-time. The time between 2 and 3 is the hold-time. The lockdep held-lock tracking code is reused, because it already collects locks into meaningful groups (classes), and because it is an existing infrastructure for lock instrumentation. Currently lockdep tracks lock acquisition with two hooks: lock() lock_acquire() _lock() ... code protected by lock ... unlock() lock_release() _unlock() We need to extend this with two more hooks, in order to measure contention. lock_contended() - used to measure contention events lock_acquired() - completion of the contention These are then placed the following way: lock() lock_acquire() if (!_try_lock()) lock_contended() _lock() lock_acquired() ... do locked stuff ... unlock() lock_release() _unlock() (Note: the try_lock() 'trick' is used to avoid instrumenting all platform dependent lock primitive implementations.) It is also possible to toggle the two lockdep features at runtime using: /proc/sys/kernel/prove_locking /proc/sys/kernel/lock_stat (esp. turning off the O(n^2) prove_locking functionaliy can help) [akpm@linux-foundation.org: build fixes] [akpm@linux-foundation.org: nuke unneeded ifdefs] Signed-off-by: NPeter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: NIngo Molnar <mingo@elte.hu> Acked-by: NJason Baron <jbaron@redhat.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Use the lockdep infrastructure to track lock contention and other lock statistics. It tracks lock contention events, and the first four unique call-sites that encountered contention. It also measures lock wait-time and hold-time in nanoseconds. The minimum and maximum times are tracked, as well as a total (which together with the number of event can give the avg). All statistics are done per lock class, per write (exclusive state) and per read (shared state). The statistics are collected per-cpu, so that the collection overhead is minimized via having no global cachemisses. This new lock statistics feature is independent of the lock dependency checking traditionally done by lockdep; it just shares the lock tracking code. It is also possible to enable both and runtime disabled either component - thereby avoiding the O(n^2) lock chain walks for instance. This patch: raw_spinlock_t should not use lockdep (and doesn't) since lockdep itself relies on it.

This change passes the --build-id when linking the kernel and when linking modules, if ld supports it. This is a new GNU ld option that synthesizes an ELF note section inside the read-only data. The note in this section contains unique identifying bits called the "build ID", which are generated so as to be different for any two linked ELF files that aren't identical. The build ID can be recovered from stripped files, memory dumps, etc. and used to look up the original program built, locate debuginfo or other details or history associated with it. For normal program linking, the compiler passes --build-id to ld by default, but the option is needed when using ld directly as we do.
