Kconfig: introduce ARCH_DEFCONFIG to DEFCONFIG_LIST

2008-05-25T21:03:18+00:00

init/Kconfig contains a list of configs that are searched for if 'make *config' are used with no .config present. Extend this list to look at the config identified by ARCH_DEFCONFIG. With this change we now try the defconfig targets last. This fixes a regression reported by: Linus Torvalds Signed-off-by: Sam Ravnborg Cc: Linus Torvalds Cc: Thomas Gleixner Cc: Ingo Molnar Cc: "H.

initcalls: Fix m68k build and possible buffer overflow

2008-05-16T01:20:06+00:00

This patch fixes a build bug on m68k - gcc decides to emit a call to the strlen library function, which we don't implement. More importantly - my previous patch "init: don't lose initcall return values" (commit e662e1cfd434aa234b72fbc781f1d70211cb785b) had introduced potential buffer overflow by wrong calculation of string accumulator size. Use strlcat() instead, fixing both bugs. Many thanks Andreas Schwab and Geert Uytterhoeven for helping to catch and fix the bug.

Split up 'do_initcalls()' into two simpler functions

2008-05-16T01:14:01+00:00

One function to just loop over the entries, one function to actually do the call and the associated debugging code. Signed-off-by: Linus Torvalds

Clean up 'print_fn_descriptor_symbol()' types

2008-05-16T00:50:37+00:00

Everybody wants to pass it a function pointer, and in fact, that is what you _must_ pass it for it to make sense (since it knows that ia64 and ppc64 use descriptors for function pointers and fetches the actual address from there). So don't make the argument be a 'unsigned long' and force everybody to add a cast. Signed-off-by: Linus Torvalds

block: do_mounts - accept root=

2008-05-14T17:37:57+00:00

Some devices, like md, may create partitions only at first access, so allow root= to be set to a valid non-existant partition of an existing disk. This applies only to non-initramfs root mounting. This fixes a regression from 2.6.24 which did allow this to happen and broke some users machines :( Acked-by: Neil Brown Tested-by: Joao Luis Meloni Assirati Cc: stable Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman

init: don't lose initcall return values

2008-05-13T15:02:25+00:00

There is an ability to lose an initcall return value if it happened with irq disabled or imbalanced preemption (and if we debug initcall). Signed-off-by: Cyrill Gorcunov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

module: don't ignore vermagic string if module doesn't have modversions

2008-05-09T14:45:18+00:00

Linus found a logic bug: we ignore the version number in a module's vermagic string if we have CONFIG_MODVERSIONS set, but modversions also lets through a module with no __versions section for modprobe --force (with tainting, but still). We should only ignore the start of the vermagic string if the module actually *has* crcs to check. Rather than (say) having an entertaining hissy fit and creating a config option to work around the buggy code. Signed-off-by: Rusty Russell Signed-off-by: Linus Torvalds

pcspkr: fix dependancies

sched: default to n for GROUP_SCHED and FAIR_GROUP_SCHED

2008-05-05T21:56:18+00:00

GROUP_SCHED is confirmed to cause unacceptable latencies, see: http://lkml.org/lkml/2008/5/2/370. Mark it EXPERIMENTAL and default to no for now. Signed-off-by: Parag Warudkar Signed-off-by: Ingo Molnar
