sh: kexec: Add PHYSICAL_START

2011-10-28T06:03:43+00:00

Add PHYSICAL_START kernel configuration parameter to set the address at
which the kernel should be loaded.

It has been observed on an sh7757lcr that simply modifying MEMORY_START
does not achieve this goal for 32bit sh. This is due to MEMORY_OFFSET in
arch/sh/kernel/vmlinux.lds.S bot being based on MEMORY_START on such
systems.

perf: Remove the nmi parameter from the swevent and overflow interface

2011-07-01T09:06:35+00:00

The nmi parameter indicated if we could do wakeups from the current
context, if not, we would set some state and self-IPI and let the
resulting interrupt do the wakeup.

For the various event classes:

  - hardware: nmi=0; PMI is in fact an NMI or we run irq_work_run from
    the PMI-tail (ARM etc.)
  - tracepoint: nmi=0; since tracepoint could be from NMI context.
  - software: nmi=[0,1]; some, like the schedule thing cannot
    perform wakeups, and hence need 0.

As one can see, there is very little nmi=1 usage, and the down-side of
not using it is that on some platforms some software events can have a
jiffy delay in wakeup (when arch_irq_work_raise isn't implemented).

The up-side however is that we can remove the nmi parameter and save a
bunch of conditionals in fast paths.

sh: use printk_ratelimited instead of printk_ratelimit

Follows the powerpc change, for much the same rationale.

sh: fix wrong icache/dcache address-array start addr in cache-debugfs.

2011-06-06T03:30:02+00:00

This patch fixes a icache/dcache address-array start address while
dumping its entires in debugfs. Perviously the code was attempting to
remember the address in static variable, which is no more required
for debugfs, as the function can be executed in one pass.

Without this patch the start address ends up in wrong place and the
/sys/kernel/debug/sh/icache or dcache debugfs contents may not be correct.

sh64: Move from P1SEG to CAC_ADDR for consistent sync.

2011-05-31T05:38:29+00:00

sh64 doesn't define a P1SEGADDR, resulting in a build failure. The proper
mapping can be attained for both sh32 and 64 via the CAC_ADDR macro, so
switch to that instead.

sh: pmb: Use struct syscore_ops instead of sysdevs

2011-03-23T10:05:18+00:00

This converts the PMB code over to use the new syscore_ops and kills off
the old sysdev utilization, as per Rafael's example.
