2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

2011-01-13kernel: clean up USE_GENERIC_SMP_HELPERSAmerigo Wang
For arch which needs USE_GENERIC_SMP_HELPERS, it has to select USE_GENERIC_SMP_HELPERS, rather than leaving a choice to user, since they don't provide their own implementions. Also, move on_each_cpu() to kernel/smp.c, it is strange to put it in kernel/softirq.c. For arch which doesn't use USE_GENERIC_SMP_HELPERS, e.g. blackfin, only on_each_cpu() is compiled.

2011-01-13set_rtc_mmss: show warning message only onceStephen Hemminger
Occasionally the system gets into a state where the CMOS clock has gotten slightly ahead of current time and the periodic update of RTC fails. The message is a nuisance and repeats spamming the log. See: http://www.ntp.org/ntpfaq/NTP-s-trbl-spec.htm#Q-LINUX-SET-RTC-MMSS Rather than just removing the message, make it show only once and reduce severity since it indicates a normal and non urgent condition.

2010-10-27mm: fix race in kunmap_atomic()Peter Zijlstra
Christoph reported a nice splat which illustrated a race in the new stack based kmap_atomic implementation. The problem is that we pop our stack slot before we're completely done resetting its state -- in particular clearing the PTE (sometimes that's CONFIG_DEBUG_HIGHMEM). If an interrupt happens before we actually clear the PTE used for the last slot, that interrupt can reuse the slot in a dirty state, which triggers a BUG in kmap_atomic(). Fix this by introducing kmap_atomic_idx() which reports the current slot index without actually releasing it and use that to find the PTE and delay the _pop() until after we're completely done.

2010-10-27MN10300: Map userspace atomic op regs as a vmalloc pageMark Salter
The AM34 processor has an atomic operation that's the equivalent of LL/SC on other architectures. However, rather than being done through a pair of instructions, it's driven by writing to a pair of memory-mapped CPU control registers. One set of these registers (AARU/ADRU/ASRU) is available for use by userspace, but for userspace to access them a PTE must be set up to cover the region. This is done by dedicating the first vmalloc region page to this purpose, setting the permissions on its PTE such that userspace can access the page. glibc is hardcoded to expect the registers to be there. The way atomic ops are done through these registers is straightforward: (1) Write the address of the word you wish to access into AARU. This causes the CPU to go and fetch that word and load it into ADRU. The status bits are also cleared in ASRU. (2) The current data value is read from the ADRU register and modified. (3) To alter the data in RAM, the revised data is written back to the ADRU register, which causes the CPU to attempt to write it back. (4) The ASRU.RW flag (ASRU read watch), ASRU.LW flag (bus lock watch), ASRU.IW (interrupt watch) and the ASRU.BW (bus error watch) flags then must be checked to confirm that the operation wasn't aborted. If any of the watches have been set to true, the operation was aborted. Signed-off-by: Mark Salter <msalter@redhat.com> Signed-off-by: David Howells <dhowells@redhat.com>
