2008-05-07cfq-iosched: make io priorities inherit CPU scheduling class as well as niceJens Axboe
We currently set all processes to the best-effort scheduling class, regardless of what CPU scheduling class they belong to. Improve that so that we correctly track idle and rt scheduling classes as well. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-05-07vfs: splice remove_suid() cleanupMiklos Szeredi
generic_file_splice_write() duplicates remove_suid() just because it doesn't hold i_mutex. But it grabs i_mutex inside splice_from_pipe() anyway, so this is rather pointless. Move locking to generic_file_splice_write() and call remove_suid() and __splice_from_pipe() instead. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-05-06x86: fix PAE pmd_bad bootup warningHugh Dickins
Fix warning from pmd_bad() at bootup on a HIGHMEM64G HIGHPTE x86_32. That came from 9fc34113f6880b215cbea4e7017fc818700384c2 x86: debug pmd_bad(); but we understand now that the typecasting was wrong for PAE in the previous version: pagetable pages above 4GB looked bad and stopped Arjan from booting. And revert that cded932b75ab0a5f9181ee3da34a0a488d1a14fd x86: fix pmd_bad and pud_bad to support huge pages. It was the wrong way round: we shouldn't weaken every pmd_bad and pud_bad check to let huge pages slip through - in part they check that we _don't_ have a huge page where it's not expected. Put the x86 pmd_bad() and pud_bad() definitions back to what they have long been: they can be improved (x86_32 should use PTE_MASK, to stop PAE thinking junk in the upper word is good; and x86_64 should follow x86_32's stricter comparison, to stop thinking any subset of required bits is good); but that should be a later patch. Fix Hans' good observation that follow_page() will never find pmd_huge() because that would have already failed the pmd_bad test: test pmd_huge in between the pmd_none and pmd_bad tests. Tighten x86's pmd_huge() check? No, once it's a hugepage entry, it can get quite far from a good pmd: for example, PROT_NONE leaves it with only ACCESSED of the KERN_PGTABLE bits. However... though follow_page() contains this and another test for huge pages, so it's nice to keep it working on them, where does it actually get called on a huge page? get_user_pages() checks is_vm_hugetlb_page(vma) to to call alternative hugetlb processing, as does unmap_vmas() and others.

2008-05-06libata: improve post-reset device ready testTejun Heo
Some controllers (jmb and inic162x) use 0x77 and 0x7f to indicate that the device isn't ready yet. It looks like they use 0xff if device presence is detected but connection isn't established. 0x77 or 0x7f after connection is established and use the value from signature FIS after receiving it. This patch implements ata_check_ready(), which takes TF status value and determines whether the port is ready or not considering the above and other conditions, and use it in @check_ready() functions. This is safe as both 0x77 and 0x7f aren't valid ready status value even though they have BSY bit cleared. This fixes hot plug detection failures which can be triggered with certain drives if they aren't already spun up when the data connector is hot plugged. Tested on sil, sil24, ahci (jmb/ich), piix and inic162x combined with eight drives from all major vendors. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

this replaces the rq->clock stuff (and possibly cpu_clock()). - architectures that have an 'imperfect' hardware clock can set CONFIG_HAVE_UNSTABLE_SCHED_CLOCK - the 'jiffie' window might be superfulous when we update tick_gtod before the __update_sched_clock() call in sched_clock_tick() - cpu_clock() might be implemented as: sched_clock_cpu(smp_processor_id()) if the accuracy proves good enough - how far can TSC drift in a single jiffie when considering the filtering and idle hooks?

Dmitry Adamushko pointed out a logic error in task_wake_up_rt() where we will always evaluate to "true". You can find the thread here: http://lkml.org/lkml/2008/4/22/296 In reality, we only want to try to push tasks away when a wake up request is not going to preempt the current task. So lets fix it. Note: We introduce test_tsk_need_resched() instead of open-coding the flag check so that the merge-conflict with -rt should help remind us that we may need to support NEEDS_RESCHED_DELAYED in the future, too.

2008-05-03unified (weak) sys_pipe implementationUlrich Drepper
This replaces the duplicated arch-specific versions of "sys_pipe()" with one unified implementation. This removes almost 250 lines of duplicated code. It's marked __weak, so that *if* an architecture wants to override the default implementation it can do so by simply having its own replacement version, since many architectures use alternate calling conventions for the 'pipe()' system call for legacy reasons (ie traditional UNIX implementations often return the two file descriptors in registers) I still haven't changed the cris version even though Linus says the BKL isn't needed. The arch maintainer can easily do it if there are really no obstacles. Signed-off-by: Ulrich Drepper <drepper@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-05-03hrtimer: remove duplicate helper functionOliver Hartkopp
The helper function hrtimer_callback_running() is used in kernel/hrtimer.c as well as in the updated net/can/bcm.c which now supports hrtimers. Moving the helper function to hrtimer.h removes the duplicate definition in the C-files.

2008-05-02bridge: forwarding table information for >256 devicesStephen Hemminger
The forwarding table binary interface (my bad choice), only exposes the port number of the first 8 bits. The bridge code was limited to 256 ports at the time, but now the kernel supports up 1024 ports, so the upper bits are lost when doing: brctl showmacs The fix is to squeeze the extra bits into small hole left in data structure, to maintain binary compatiablity.

2008-05-02types: add C99-style constructors to <asm-generic/int-*.h>H. Peter Anvin
Add C99-style constructor macros for fixed types to <asm-generic/int-*.h>. Since Linux uses names like "u64" instead of "uint64_t", the constructor macros are called U64_C() instead of UINT64_C() and so forth. These macros allow specific sizes to be specified as U64_C(0x123456789abcdef), without gcc issuing warnings as it will if one writes (u64)0x123456789abcdef. When used from assembly, these macros pass their argument unchanged. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
