The sh architecture has some code in the .text.init section, but it does not reference that section in its linker scripts. This change moves this code from the .text.init section to the .init.text section, which is presumably where it belongs.

This corrects a race with the PHY RST bit not being set properly if the PLL status changes right before timeout. This resulted in it potentially failing even if the device came up in time.

There were a number of issues with the DSP context save/restore code, mostly left-over relics from when it was introduced on SH3-DSP with little follow-up testing, resulting in things like task_pt_dspregs() referencing incorrect state on the stack. This follows the MIPS convention of tracking the DSP state in the thread_struct and handling the state save/restore in switch_to() and finish_arch_switch() respectively. The regset interface is also updated, which allows us to finally be rid of task_pt_dspregs() and the special cased task_pt_regs().

Forcing direct-mapped worked on certain older 2-way set associative parts, but was always error prone on 4-way parts. As these are the norm these days, there is not much point in continuing to support this mode. Most of the folks that used direct-mapped mode generally just wanted writethrough caching in the first place.. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

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.

This provides a method for supporting fixed PMB mappings inherited from the bootloader, as an alternative to the dynamic PMB mapping currently used by the kernel.

Add Suspend-to-disk / swsusp / CONFIG_HIBERNATION support to the SuperH architecture. To suspend, use "swapon /dev/sda2; echo disk > /sys/power/state" To resume, pass "resume=/dev/sda2" on the kernel command line. The patch "pm: rework includes, remove arch ifdefs V2" is needed to allow the generic swsusp code to build properly. Hibernation is not enabled with this patch though, a patch setting ARCH_HIBERNATION_POSSIBLE will be submitted later.
