lmb: rename to memblock

2010-07-14T07:14:00+00:00

via following scripts

      FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')

      sed -i \
        -e 's/lmb/memblock/g' \
        -e 's/LMB/MEMBLOCK/g' \
        $FILES

      for N in $(find . -name lmb.[ch]); do
        M=$(echo $N | sed 's/lmb/memblock/g')
        mv $N $M
      done

and remove some wrong change like lmbench and dlmb etc.

also move memblock.c from lib/ to mm/

sh: rework memory limits to work with LMB.

2010-05-10T11:17:25+00:00

This reworks the memory limit handling to tie in through the available
LMB infrastructure. This requires a bit of reordering as we need to have
all of the LMB reservations taken care of prior to establishing the
limits.

While we're at it, the crash kernel reservation semantics are reworked
so that we allocate from the bottom up and reduce the risk of having
to disable the memory limit due to a clash with the crash kernel
reservation.

sh: Ensure that X2 TLB settings are reflected in vmcore.

2010-05-07T08:14:00+00:00

This rolls in the X2TLB config settings for vmcore.

sh: convert kexec crash kernel management to LMB.

2010-05-07T05:54:55+00:00

This migrates the crash kernel handling off of bootmem and over to LMB.

sh: machine_ops based reboot support.

2010-01-20T07:42:52+00:00

This provides a machine_ops-based reboot interface loosely cloned from
x86, and converts the native sh32 and sh64 cases over to it.

Necessary both for tying in SMP support and also enabling platforms like
SDK7786 to add support for their microcontroller-based power managers.

sh: Tidy up the sh bios VBR handling.

2010-01-12T05:50:43+00:00

This moves the VBR handling out of the main trap handling code and in to
the sh-bios helper code. A couple of accessors are added in order to
permit other kernel code to get at the VBR value for state save/restore
paths.

sh: fix kexec by removing check for old kexec-tools

2009-10-26T10:45:45+00:00

This unbreaks kexec support. Without this fix all
cases of kexec fails since __pa() does not behave
like PHYSADDR(). The downside is that we also kill
the code blocking users running old kexec-tools.

sh: Obliterate the P1 area macros

2009-10-10T12:51:02+00:00

Replace the use of PHYSADDR() with __pa(). PHYSADDR() is based on the
idea that all addresses in P1SEG are untranslated, so we can access an
address's physical page as an offset from P1SEG. This doesn't work for
CONFIG_PMB/CONFIG_PMB_FIXED because pages in P1SEG and P2SEG are used
for PMB mappings and so can be translated to any physical address.

Likewise, replace a P1SEGADDR() use with virt_to_phys().

sh: disallow kexec virtual entry

2009-03-20T09:56:04+00:00

Older versions of kexec-tools has a zImage loader that
passes a virtual address as entry point. The elf loader
otoh it passes a physical address as entry point, and
pages are always passed as physical addresses as well.

Only allow physical addresses from now on.
