2011-05-26x86/ftrace: Fix compiler warning in ftrace.cRakib Mullick1-6/+6
Due to commit dc326fca2b64 (x86, cpu: Clean up and unify the NOP selection infrastructure), we get the following warning: arch/x86/kernel/ftrace.c: In function ‘ftrace_make_nop’: arch/x86/kernel/ftrace.c:308:6: warning: assignment discards qualifiers from pointer target type arch/x86/kernel/ftrace.c: In function ‘ftrace_make_call’: arch/x86/kernel/ftrace.c:318:6: warning: assignment discards qualifiers from pointer target type ftrace_nop_replace() now returns const unsigned char *, so change its associated function/variable to its compatible type to keep compiler clam.

2011-05-23watchdog: Change the default timeout and configure nmi watchdog period based ↵Mandeep Singh Baines1-2/+2
on watchdog_thresh Before the conversion of the NMI watchdog to perf event, the watchdog timeout was 5 seconds. Now it is 60 seconds. For my particular application, netbooks, 5 seconds was a better timeout. With a short timeout, we catch faults earlier and are able to send back a panic. With a 60 second timeout, the user is unlikely to wait and will instead hit the power button, causing us to lose the panic info. This change configures the NMI period to watchdog_thresh and sets the softlockup_thresh to watchdog_thresh * 2. In addition, watchdog_thresh was reduced to 10 seconds as suggested by Ingo Molnar.

2011-05-20extable, core_kernel_data(): Make sure all archs define _sdataSteven Rostedt6-0/+9
A new utility function (core_kernel_data()) is used to determine if a passed in address is part of core kernel data or not. It may or may not return true for RO data, but this utility must work for RW data. Thus both _sdata and _edata must be defined and continuous, without .init sections that may later be freed and replaced by volatile memory (memory that can be freed). This utility function is used to determine if data is safe from ever being freed. Thus it should return true for all RW global data that is not in a module or has been allocated, or false otherwise. Also change core_kernel_data() back to the more precise _sdata condition and document the function.

2011-05-19m68k: bitops - Never step beyond the end of the bitmapGeert Uytterhoeven1-26/+55
find_next bitops on m68k (find_next_zero_bit, find_next_bit, and find_next_bit_le) may cause out of bounds memory access when the bitmap size in bits % 32 != 0 and offset (the bitnumber to start searching at) is very close to the bitmap size. For example, unsigned long bitmap[2] = { 0, 0 }; find_next_bit(bitmap, 63, 62); 1. find_next_bit() tries to find any set bits in bitmap[1], but no bits set. 2. Then find_first_bit(bimap + 2, -1) 3. Unfortunately find_first_bit() takes unsigned int as the size argument. 4. find_first_bit will access bitmap[2~] until it find any set bits. Add missing tests for stepping beyond the end of the bitmap to all find_{first,next}_*() functions, and make sure they never return a value larger than the bitmap size.

2011-05-19x86: Don't unmask disabled irqs when migrating themTian, Kevin1-1/+2
It doesn't make sense to unconditionally unmask a disabled irq when migrating it from offlined cpu to another. If the irq triggers then it will be disabled in the interrupt handler anyway. So we can just avoid unmasking it.
