2007-11-05[S390] tod clock: announce clocksource as perfectChristian Borntraeger
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.

2007-11-05[S390] Rename "idle_time" attribute to "idle_time_us".Heiko Carstens
Seems that people prefer to have the unit encoded in the attribute name. Also makes parsing easier. Now we have: # cat /sys/devices/system/cpu/cpu0/idle_time_us 131473592 instead of # cat /sys/devices/system/cpu/cpu0/idle_time 131473592 us Cc: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2007-11-05[S390] Fix memory detection.Heiko Carstens
Yet another patch in the countless series of memory detection fixes: if the last area of the reported storage size is a hole the detection loop will loop forever. Just break chunk detection loop if its end is going to be larger than reported storage size.

2007-11-05[S390] Fix compile on !CONFIG_SMP.Heiko Carstens
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. For the time being this is good enough. arch/s390/kernel/built-in.o: In function `do_monitor_call': (.text+0x50d4): undefined reference to `per_cpu__s390_idle' arch/s390/kernel/built-in.o: In function `cpu_idle': (.text+0x518c): undefined reference to `per_cpu__s390_idle' make: *** [.tmp_vmlinux1] Error 1 Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2007-11-02Use i8253.c lock for PC speaker on MIPS, too.Ralf Baechle
The Jazz machines have to use the PIT timer for dyntick and highresolution kernels. This may break because currently just like i386 used to do MIPS uses two separate spinlocks in the actual PIT code and the PC speaker code. So switch to do it the same that x86 currently does PIT locking. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-11-02sh: Fix up r7780rp highlander CF access size.Paul Mundt
R7780RP can't do byte-sized accesses to CF, so needs to do word sized access with low-byte masking. 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!

2007-11-02sh: Terminate .eh_frame in VDSO with a 4-byte 0.Kaz Kojima
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.

2007-11-02sh: Decouple 4k and soft/hardirq stacks.Paul Mundt
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>

2007-10-31[SPARC64]: Fix build failure when CONFIG_BUG is disabled.David S. Miller
When CONFIG_BUG is turned off, the standard trick of: switch (x) { case X: ... case Y: ... default: BUG(); }; to mark impossible cases does not work because BUG() evalutes to nothing and thus GCC just sees a fallthrough code path. Add an explicit KERN_ERR log message and a do_exit() to trap this case. Signed-off-by: David S. Miller <davem@davemloft.net>
