| * [S390] tod clock: announce clocksource as perfectChristian Borntraeger2007-11-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Time of Day clock is the standard time source for s390. It is - monotonic - allows very fast reading - architecture guarantees at least microsecond stepping - available as part of the architecture We should announce the rate of tod as 400 to be in sync with the description found in clocksource.h: "400-499:Perfect The ideal clocksource. A must-use where available." This change will prefer tod over less reliable clock sources.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Seems that people prefer to have the unit encoded in the attribute name. Also makes parsing easier.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit fae8b22d3e3e3a3d317a7746493997af02a3f35c "[S390] Add per-cpu idle time / idle count sysfs attributes" causes a link error on !CONFIG_SMP. Fix this by adding some #ifdef's. Real fix would be to cleanup the code since we don't register a cpu on !CONFIG_SMP. But that would be quite a big patch.

This same problem exists on older versions of the R2D, with the same workaround having been implemented in 43f4b8c7578b928892b6f01d374346ae14e5eb70 there. Follow that change for the highlander boards. This does not impact R7780MP or SH7785 based Highlander modules. If you're unfortunate enough to be stuck with an R7780RP, this patch is for you!

| * | | sh: Terminate .eh_frame in VDSO with a 4-byte 0.Kaz Kojima2007-11-021-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's assumed that .eh_frame is terminated with 4-byte 0 in shared libraries and executable. It seems to be the case for VDSOs too. Without this terminator, I saw failures when unwinding from VDSO, though I don't know how other architectures handle this issue. For the normal libs, crtendS.o gives this terminator. We can use such terminating objects. Or we can add a 4-byte 0 with modifying the linker script like as the patch below.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While using separate IRQ stacks can cut down on stack consumption, many users can also use 4k stacks directly without the additional need of separate stacks for soft and hardirqs. With this split, we support the same rationale for 4KSTACKS as m68knommu, with the IRQSTACKS abstraction as per ppc64. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CPU_HAS_SR_RB is selected by both CPU_SH3 and CPU_SH4, so having a dependency and default y on those additionally doesn't make much sense. The select also has to be special cased for CPUs that don't support this. This is also something that has been abused too much as a result of being user-visible, hence the addition of the select in the first place. So just kill the user-visibility entirely while we're at it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
