* sh: Shuffle the board directories in to mach groups.Paul Mundt2008-07-29
| | | | | | | | | This flattens out the board directories in to individual mach groups, we will use this for getting rid of unneeded directories, simplifying the build system, and becoming more coherent with the refactored arch/sh/include topology. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | When I compiled Solution Engine, this become compile error because plaform device of sh_eth device becomes enable. When sh7710/sh7712 which could use sh_eth was chosen, revised it so that platform device of sh_eth device became enable.

| * powerpc: Disable 64K hugetlb support when doing 64K SPU mappingsBenjamin Herrenschmidt2008-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | The 64K SPU local store mapping feature is incompatible with the 64K huge pages support due to the inability of some parts of the memory management to differenciate between them while they use a different page table format. For now, disable 64K huge pages when CONFIG_SPU_FS_64K_LS, in the long run, this can be fixed by making this feature use the hugetlb page table format.

| * powerpc/powermac: Fixup default serial port device for pmac_zilogBenjamin Herrenschmidt2008-07-28
| | | | | | | | | | | | | | | | This removes the non-working code in legacy_serial that tried to handle the powermac SCC ports, and instead add a (now working) function to the powermac platform code to find the default serial console if any.

| * powerpc/powermac: Use sane default baudrate for SCC debuggingBenjamin Herrenschmidt2008-07-28
| | | | | | | | | | | | | | | | | | | | | | When using the "sccdbg" option to route early kernel messages and xmon to the SCC serial port on PowerMacs, when this wasn't the configured output port of Open Firmware, we initialize the baudrate to 57600bps. This isn't a very good default on some powermacs where both the FW and pmac_zilog will default to 38400. This fixes it to use the same logic as pmac_zilog to pick a default speed.

| * powerpc: Show processor cache information in sysfsNathan Lynch2008-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Collect cache information from the OF device tree and display it in the cpu hierarchy in sysfs. This is intended to be compatible at the userspace level with x86's implementation[1], hence some of the funny attribute names. The arrangement of cache info is not immediately intuitive, but (again) it's for compatibility's sake. The cache attributes exposed are: type (Data, Instruction, or Unified) level (1, 2, 3...) size coherency_line_size number_of_sets ways_of_associativity All of these can be derived on platforms that follow the OF PowerPC Processor binding. The code "publishes" only those attributes for which it is able to determine values; attributes for values which cannot be determined are not created at all.

| * powerpc: Make core id information available to userspaceNathan Lynch2008-07-28
| | | | | | | | | | | | | | | | | | | | Existing Open Firmware practice is to report each processor core as a separate node in the device tree. Report the value of the "reg" OF property corresponding to a logical CPU's device node as the core_id attribute in /sys/devices/system/cpu/cpu*/topology/core_id.

| | | | | | | | | | | | | | | | | | | | | | | | Implement the notion of "core siblings" for powerpc. This makes /sys/devices/system/cpu/cpu*/topology/core_siblings present sensible values, indicating online CPUs which share an L2 cache.

| * powerpc: Add TIF_NOTIFY_RESUME support for tracehookRoland McGrath2008-07-28
| | | | | | | | | | | | | | | | | | | | | | This adds TIF_NOTIFY_RESUME support for powerpc. When set, we call tracehook_notify_resume() on the way to user mode. This overloads do_signal() to do the work, but changes its arguments to it has the TIF_* bits handy in a register and drops the useless first argument that was always zero.

| * powerpc: Make syscall tracing use tracehook.h helpersRoland McGrath2008-07-28
| | | | | | | | | | | | | | | | | | | | | | | | This changes powerpc syscall tracing to use the new tracehook.h entry points. There is no change, only cleanup. In addition, the assembly changes allow do_syscall_trace_enter() to abort the syscall without losing the information about the original r0 value.

| * powerpc: Call tracehook_signal_handler() when setting up signal framesRoland McGrath2008-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | This makes the powerpc signal handling code call tracehook_signal_handler() after a handler is set up. This means that using PTRACE_SINGLESTEP to enter a signal handler will report to ptrace on the first instruction of the handler, instead of the second. This is consistent with what x86 and other machines do, and what users and debuggers want. BenH: Fixed up the test for the trap value.

| * powerpc: Update cpu_sibling_maps dynamicallyNathan Lynch2008-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | Rather doing one initialization pass over all the per-cpu cpu_sibling_maps at boot, update the maps at cpu online/offline time. This is a behavior change -- the thread_siblings attribute now reflects only online siblings, whereas it would display offline siblings before. The new behavior matches that of x86, and is arguably more useful. Signed-off-by: Nathan Lynch <ntl@pobox.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | This piece of code is broken for >2 threads, and possibly in some other subtle ways (such as comparing a value obtained from an "ibm,ppc-interrupt-server#s" property to a value obtained from a "reg" property) and doesn't seem to have any useful purpose in the first place other than a dubious warning in case NR_CPUS is too small, which probably isn't the right place to do so.
