* brk: COMPAT_BRK: fix detection of randomized brkJiri Kosina2011-04-143-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 5520e89 ("brk: fix min_brk lower bound computation for COMPAT_BRK") tried to get the whole logic of brk randomization for legacy (libc5-based) applications finally right. It turns out that the way to detect whether brk has actually been randomized in the end or not introduced by that patch still doesn't work for those binaries, as reported by Geert: : /sbin/init from my old m68k ramdisk exists prematurely. : : Before the patch: : : | brk(0x80005c8e) = 0x80006000 : : After the patch: : : | brk(0x80005c8e) = 0x80005c8e : : Old libc5 considers brk() to have failed if the return value is not : identical to the requested value. I don't like it, but currently see no better option than a bit flag in task_struct to catch the CONFIG_COMPAT_BRK && randomize_va_space == 2 case.

The leds-regulator driver was ignoring the initial status of the regulator; this resulted in rdev->use_count being incremented to 2 after calling regulator_led_set_value() in the .probe method when a regulator was already enabled at insmod time, which made it impossible to ever disable the regulator.

* mm/page_alloc.c: silence build_all_zonelists() section mismatchPaul Mundt2011-04-141-1/+1
| | | | | | | | | | | | | | | | | | | | The memory hotplug case involves calling to build_all_zonelists() which in turns calls in to setup_zone_pageset(). The latter is marked __meminit while build_all_zonelists() itself has no particular annotation. build_all_zonelists() is only handed a non-NULL pointer in the case of memory hotplug through an existing __meminit path, so the setup_zone_pageset() reference is always safe. The options as such are either to flag build_all_zonelists() as __ref (as per __build_all_zonelists()), or to simply discard the __meminit annotation from setup_zone_pageset().

* fs/partitions/ldm.c: fix oops caused by corrupted partition tableTimo Warns2011-04-141-4/+12
| | | | | | | | | | | | | | | | | | The kernel automatically evaluates partition tables of storage devices. The code for evaluating LDM partitions (in fs/partitions/ldm.c) contains a bug that causes a kernel oops on certain corrupted LDM partitions. A kernel subsystem seems to crash, because, after the oops, the kernel no longer recognizes newly connected storage devices. The patch validates the value of vblk_size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | platform_get_irq returns -ENXIO on failure, so !int_irq was probably always true. Better use (int)int_irq <= 0. Note that a return value of zero is still handled as error even though this could mean irq0. This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that changed the return value of platform_get_irq from 0 to -ENXIO on error.

Also, the use of is_global_init() is not correct in the multhreaded case, as Oleg Nesterov explains, "is_global_init() is not right in theory, /sbin/init can be multithreaded. And, this doesn't cover the sub-namespace inits... I'd suggest to check SIGNAL_UNKILLABLE, but looking closer I think you can simply remove this code." It seems this code was copied from arch/powerpc in March 2007 in commit 623b0355d5b1 "[AVR32] Clean up exception handling code" but the code was deleted from arch/powerpc in November 2009 in commit a0592d42fe3e "powerpc: kill the obsolete code under is_global_init()" So catch up with powerpc and delete the bogus code.

| | * | | drm/nv50: use "nv86" tlb flush method on everything except 0x50/0xacBen Skeggs2011-04-053-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been reported that this greatly improves (and possibly fixes completely) the stability of NVA3+ chipsets. In traces of my NVA8, NVIDIA now appear to be doing this too. The most recent traces of 0x50 and 0xac I could find don't show NVIDIA checking PGRAPH status on these flushes, so for now, we won't either. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
