| | | | | | | | | | | | | | | | | | | | This is mandatory for 64-bit processes, and doing it also for 32-bit processes saves a conditional in the compat case. This fixes the glibc/nptl/tst-stdio1 test case, as well as many others, on 64-bit. Signed-off-by: David S. Miller <davem@davemloft.net>

* sparc64: Fix IRQ ->set_affinity() methods.David S. Miller2010-01-201-9/+28
| | | | | | | | | | As noted by Benjamin Herrenschmidt, the generic IRQ layer only sets irq_desc[irq].affinity after ->set_affinity() succeeds. So we have to use the passed in cpumask. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | pcibus_to_node can return -1 if we cannot determine which node a pci bus is on. If passed -1, cpumask_of_node will negatively index the lookup array and pull in random data: # cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus 00000000,00000003,00000000,00000000 # cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist 64-65 Change cpumask_of_node to check for -1 and return cpu_all_mask in this case: # cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus ffffffff,ffffffff,ffffffff,ffffffff # cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist 0-127 Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: David S.

* sparc: convert to arch_gettimeoffset()John Stultz2010-01-154-179/+46
| | | | | | | | | | | | | | | | | | | This patch converts sparc (specifically sparc32) to use GENERIC_TIME via the arch_getoffset() infrastructure, reducing the amount of arch specific code we need to maintain. The sparc architecture is one of the last 3 arches that need to be converted. This patch applies on top of Linus' current -git tree I've taken my best swing at converting this, but I'm not 100% confident I got it right. My cross-compiler is now out of date (gcc4.2) so I wasn't able to check if it compiled. Any assistance from arch maintainers or testers to get this merged would be great.

| | | | | | | | | | | | It doesn't account for phys_base like it should, fix by using page_to_pfn(). While we're here, make virt_to_page() use pfn_to_page() as well, so we consistently use the asm/memory-model.h abstractions instead of open-coding memory model assumptions.

| | | | | | | | | | | | | Make sure compiler won't do weird things with limits. E.g. fetching them twice may return 2 different values after writable limits are implemented.

| | | | | | | | | | | | | | From: Heiko Carstens <heiko.carstens@de.ibm.com> Callers of copy_from_user() expect it to return the number of bytes it could not copy. In no case it is supposed to return -EFAULT. In case of a detected buffer overflow just return the requested length. In addition one could think of a memset that would clear the size of the target object. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

First, the softirq range check forgets to subtract STACK_BIAS before comparing with %sp. Next, on failure the wrong label is jumped to, resulting in a bogus stack being loaded.
