* [AVR32] Don't enable clocks with no usersHaavard Skinnemoen2007-04-27
| | | | | | | | | Bring the code that sets the initial PM clock masks in line with the comment preceding it by only enabling clocks that have users != 0. Fix SM clock definition and avr32_hpt_init() so that the SM and TC0 clocks keep ticking. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Put cpu in sleep 0 when idle.Hans-Christian Egtvedt2007-04-27
| | | | | | | | | This patch puts the CPU in sleep 0 when doing nothing, idle. This will turn of the CPU clock and thus save power. The CPU is waken again when an interrupt occurs. Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Change system timer from count-compare to Timer/Counter 0Hans-Christian Egtvedt2007-04-27
| | | | | | | | | | | | | | | | | | | | Due to limitation of the count-compare system timer (not able to count when CPU is in sleep), the system timer had to be changed to use a peripheral timer/counter. The old COUNT-COMPARE code is still present in time.c as weak functions. The new timer is added to the architecture directory. This patch sets up TC0 as system timer The new timer has been tested on AT32AP7000/ATSTK1000 at 100 Hz, 250 Hz, 300 Hz and 1000 Hz. For more details about the timer/counter see the datasheet for AT32AP700x available at http://www.atmel.com/dyn/products/product_card.asp?part_id=3903 Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

| | | | | | | | | | | | | | | | change_page_attr on x86-64 only flushed the TLB for pages that got reverted. That's not correct: it has to be flushed in all cases. This bug was added in some earlier changes. Just flush all pages for now. This could be done more efficiently, but for this late in the release this seem to be the best fix.

* [PATCH] x86: Remove noreplacement optionAndi Kleen2007-04-24
| | | | | | | | | | | | | | noreplacement is dangerous on modern systems because it will not replace the context switch FNSAVE with SSE aware FXSAVE. But other places in the kernel still assume SSE and do FXSAVE and the CPU will then access FXSAVE information with FNSAVE and cause corruption. Easiest way to avoid this is to remove the option. It was mostly for paranoia reasons anyways and alternative()s have been stable for some time. Thanks to Jeremy F. for reporting and helping debug it. Signed-off-by: Andi Kleen <ak@suse.de>

The RLIMIT_NOFILE resource limit is what sysconf (_SC_OPEN_MAX) actually wants to return. The CHILD_MAX cases weren't actually using anything I want to get rid of, but I noticed that they are there and are wrong too. The CHILD_MAX value is not really unlimited as a -1 return from sysconf indicates. The RLIMIT_NPROC resource limit is what sysconf (_SC_CHILD_MAX) wants to return.

The best workaround is to issue an explicit flush in kmap_atomic_functions case; this is the only way nested PTE updates can happen in the interrupt handler.
