This adds in support for building with ARCH=sh64 using the sh SRCARCH. This tidies up the randconfig generation somewhat to make sure that we don't end up with impossible configurations, and without having to rely on things like KCONFIG_ALLCONFIG to detect the proper CPU support subset.

Add kexec jump support to the SuperH architecture. Similar to the x86 implementation, with the following exceptions: - Instead of separating the assembly code flow into two parts for regular kexec and kexec jump we use a single code path. In the assembly snippet regular kexec is just kexec jump that never comes back. - Instead of using a swap page when moving data between pages the page copy assembly routine has been modified to exchange the data between the pages using registers. - We walk the page list twice in machine_kexec() to do and undo physical to virtual address conversion.

This adds support for extended ASIDs (up to 16-bits) on newer SH-X3 cores that implement the PTAEX register and respective functionality. Presently only the 65nm SH7786 (90nm only supports legacy 8-bit ASIDs). The main change is in how the PTE is written out when loading the entry in to the TLB, as well as in how the TLB entry is selectively flushed. While SH-X2 extended mode splits out the memory-mapped U and I-TLB data arrays for extra bits, extended ASID mode splits out the address arrays. While we don't use the memory-mapped data array access, the address array accesses are necessary for selective TLB flushes, so these are implemented newly and replace the generic SH-4 implementation. With this, TLB flushes in switch_mm() are almost non-existent on newer parts. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This patch contains CONFIG_SUSPEND support to the SuperH architecture. If enabled, SuperH Mobile processors will register their suspend callbacks during boot. To suspend, use "echo mem > /sys/power/state". To allow wakeup, make sure "/sys/device/platform/../power/wakeup" contains "enabled". Additional per-device driver patches are most likely needed.

GENERIC_TIME still depends on the clocksource bits being there, which is presently not supported. This allows the CMT clockevent driver to be used alongside alternate system timers that do not yet provide a clocksource of their own (MTU2 and so on in the case of SH-2A).

SuperH CMT clockevent driver. Both 16-bit and 32-bit CMT versions are supported, but only 32-bit is tested. This driver contains support for both clockevents and clocksources, but no unregistration is supported at this point. Works fine as clock source and/or event in periodic or oneshot mode. Tested on sh7722 and sh7723, but should work with any cpu/architecture. This version is lacking clocksource and early platform driver support for now - this to minimize the amount of dependencies.

Fix up the build for mach-highlander and mach-rsk. These operated on the assumption that GENERIC_GPIO support with an optional GPIOLIB was possible. This used to be true, but has not been the case since commit-id d56cc8bc661ac1ceded8d45ba2d53bb134fee17d ("sh: use gpiolib"), where the GENERIC_GPIO implementation was rewritten to use GPIOLIB directly.

ISA can go away now that the hd6446x PCMCIA drivers no longer exist in-tree. The rationale for enabling CONFIG_ISA in the first place is likewise no longer valid given that the subsystem has changed since the time that assertion was valid. While we are at it, kill off SBUS, MCA, EISA, and so on. These are not supported and never will be. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Now that the rest of the boards that were using cf-enabler "generically" have switched to setting up their mappings on their own, only the mach-se boards were left using it. All of the cf-enabler using mach-se boards use a special initialization of the MRSHPC windows rather than going through the special PTE as other SH-4 platforms do. This consolidates the MRSHPC setup logic, hooks it up on the boards that care, and gets rid of any and all remaining references to cf-enabler. This has been long overdue, as cf-enabler has been the bane of arch/sh/kernel for the last 7 years. Good riddance. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This patch implements a new freezer subsystem in the control groups framework. It provides a way to stop and resume execution of all tasks in a cgroup by writing in the cgroup filesystem. The freezer subsystem in the container filesystem defines a file named freezer.state. Writing "FROZEN" to the state file will freeze all tasks in the cgroup. Subsequently writing "RUNNING" will unfreeze the tasks in the cgroup. Reading will return the current state. * Examples of usage : # mkdir /containers/freezer # mount -t cgroup -ofreezer freezer /containers # mkdir /containers/0 # echo $some_pid > /containers/0/tasks to get status of the freezer subsystem : # cat /containers/0/freezer.state RUNNING to freeze all tasks in the container : # echo FROZEN > /containers/0/freezer.state # cat /containers/0/freezer.state FREEZING # cat /containers/0/freezer.state FROZEN to unfreeze all tasks in the container : # echo RUNNING > /containers/0/freezer.state # cat /containers/0/freezer.state RUNNING This is the basic mechanism which should do the right thing for user space task in a simple scenario. It's important to note that freezing can be incomplete. In that case we return EBUSY. This means that some tasks in the cgroup are busy doing something that prevents us from completely freezing the cgroup at this time. After EBUSY, the cgroup will remain partially frozen -- reflected by freezer.state reporting "FREEZING" when read. The state will remain "FREEZING" until one of these things happens: 1) Userspace cancels the freezing operation by writing "RUNNING" to the freezer.state file 2) Userspace retries the freezing operation by writing "FROZEN" to the freezer.state file (writing "FREEZING" is not legal and returns EIO) 3) The tasks that blocked the cgroup from entering the "FROZEN" state disappear from the cgroup's set of tasks.
