* kbuild: check for leaked CONFIG_ symbols to userspaceSam Ravnborg2009-01-02

* headers_check.pl: disallow extern'sMike Frysinger2009-01-02
| | | | | | | | | Since prototypes with "extern" refer to kernel functions, they make no sense in userspace, so reject them automatically. Signed-off-by: Mike Frysinger <vapier@gentoo.org> [sam: made it into a warning] Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kconfig: improve error messages for bad source statementsSam Ravnborg2009-01-02

* m68k: fix recursive dependency in KconfigSam Ravnborg2009-01-02
| | | | | | | | | | | | We had a recursive dependency between MMU_MOTOROLA and MMU_SUN3 Fix it by dropping the unused dependencies on MMU_MOTOROLA. MMU_MOTOROLA is set to y only using select so any dependencies are anyway ignored.

| | | | | | | | | | | | | | | | | | | | | | | | As planed, this removes ide-scsi.

| * ide-floppy: allocate only toplevel packet commandsLinus Torvalds2009-01-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the top-level function just allocate a single pc entry, and then pass it down as a pointer to all the helper functions that also need one of those "struct ide_atapi_pc" things. As far as I can tell, the use of these things never overlaps each other, BUT I DID NOT CHECK VERY CLOSELY! So I'm not guaranteeing this is correct, and I don't have the hardware. It would be good for somebody who knows the code more, and has the hardware, could please test this? With this, ide-floppy still has fairly big stack usage, but instead of idefloppy_ioctl [vmlinux]: 1208 ide_floppy_get_capacity [vmlinux]: 872 idefloppy_release [vmlinux]: 408 idefloppy_open [vmlinux]: 408 where those two first ones are at the very top of the list of stack users for me, it's now ide_floppy_get_capacity [vmlinux]: 404 ide_floppy_ioctl [vmlinux]: 364 ie they are still high, but they are no longer at the top. Borislav: Since ide_floppy_get_capacity is passed as a function pointer to other parts of the kernel (e.g., block layer) we need that ide_atapi_pc to be created on stack. Also, redid stack users numbers above. The two functions missing from Linus' original 'make stackusage' output are due to ide being rewritten/reorganized atm.

While at it: * Don't use HWGROUP() macro in do_ide_request(). * Use __func__ in ide_intr(). This patch reduces IRQ hadling latency for IDE and improves the system-wide handling of shared IRQs (which should result in more timeout resistant and stable IDE systems). It also makes it possible to do some further changes later (i.e. replace some busy-waiting delays with sleeping equivalents). v2: Changes per review from Elias Oltmanns: - fix wrong goto statement in 'if (startstop == ide_stopped)' block - use spin_unlock_irq() - don't use obsolete HWIF() macro Cc: Elias Oltmanns <eo@nebensachen.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Take appropriate action when reservation conflicts are detected. - Correctly identify which reservation wins the conflict. - Protect alien BP reservations. - If an owned reservation loses, resize/move it. - Follow the backoff procedure before requesting additional MAS.
