| * sh: Tidy compiler warnings for SH-2A build.Paul Mundt2007-06-082-1/+1
| | | | | | | | Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Wrap CPU tuning through cc-option.Paul Mundt2007-06-081-5/+7
| | | | | | | | | | | | | | | | | | Some compilers don't support the explicit CPU tuning, while binutils is still able to handle the special subtype-specific opcodes. Make the CFLAG optional, falling back on the compiler default if nothing better exists. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: Mark sparsemem regions present earlier.Paul Mundt2007-06-081-4/+5
| | | | | | | | | | | | | | | | | | We have to call in to sparse_memory_present_with_active_regions() earlier in order for sparsemem to be happy. This was being called too late, and was causing troubles with the platforms that needed to enable sparsemem. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Register multiple nodes in topology_init().Paul Mundt2007-06-081-0/+7
| | | | | | | | | | | | If we have multiple nodes, register these at topology_init() time. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Allow for bootmem debug support.Paul Mundt2007-06-081-0/+4
| | | | | | | | | | | | Handy for debugging bootmem troubles. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: sparsemem support.Paul Mundt2007-06-083-25/+22
| | | | | | | | | | | | | | | | This implements basic sparsemem support for SH. Presently this only uses static sparsemem, and we still permit explicit selection of flatmem. Those boards that want sparsemem can select it as usual. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: Align .machvec.init section on a 4-byte boundary.Takashi YOSHII2007-06-081-0/+1
| | | | | | | | | | | | | | | | .machvec.init can be misaligned with the recent machvec changes, forcibly align it on the boundary that it expects, as before. Signed-off-by: Takashi YOSHII <takashi.yoshii.ze@hitachi.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Fix SH-4 CPU selects.Paul Mundt2007-06-083-7/+7
| | | | | | | | | | | | | | | | | | Now that select no longer works for selecting the "closest" CPU, we have to explicitly reference the precise sub-type in the few places where it actually matters (presently only setup code and some legacy sh-sci cruft). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Rip out special unknown machvec.Paul Mundt2007-06-087-48/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This kills off the BareCPU board as a "special" machvec, rather, we leave this as a default for when no other vector is available, or when we want to use it in combination with other vectors for testing with generic ops. As sh_mv is copied out anyways (or overloaded when an alternate vector is explicitly selected), this doesn't consume any additional memory. The generic machvec can be forcibly selected with sh_mv=generic, or by not having any other boards enabled. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Kill off machvec aliases.Paul Mundt2007-06-0830-71/+66
| | | | | | | | | | | | | | | | | | | | | | We now throw all of the machvecs in to .machvec.init and either select one on the command line, or copy out the first (and usually only) one to sh_mv. The rest are freed as usual. This gets rid of all of the silly sh_mv aliasing and makes the selection explicit rather than link-order dependent. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Get multiple boards in one image working again.Paul Mundt2007-06-081-38/+50
| | | | | | | | | | | | | | | | | | This tidies up the build rules and permits multiple boards to be linked in to the same kernel. The earlier Kconfig work ensures that the CPU configuration is consistent across the boards, as this is the only thing that we can't do dynamically. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Fixup cmdline handling from machvec changes.Paul Mundt2007-06-081-6/+7
| | | | | | | | | | | | | | The command line wasn't being saved off properly after the machvec changes went in, fix it up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Rework CPU/board dependencies.Paul Mundt2007-06-083-158/+165
| | | | | | | | | | | | | | | | | | This was a big mess, rework the logic a bit so that we constrain to a particular subtype and figure out the board support based on that. This makes building subtype specific kernels supporting multiple boards possible again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: Fixup machvec support.Paul Mundt2007-06-084-150/+122
| | | | | | | | | | | | | | | | This fixes up much of the machvec handling, allowing for it to be overloaded on boot. Making practical use of this still requires some Kconfig munging, however. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: __user annotations for __get/__put_user().Paul Mundt2007-06-084-14/+12
| | | | | | | | | | | | | | | | This adds in some more __user annotations. These weren't being handled properly in some of the __get_user and __put_user paths, so tidy those up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Split out CPU topology initialization.Paul Mundt2007-06-083-19/+26
| | | | | | | | | | | | | | | | | | | | Split out the CPU topology initialization to a separate file, and switch it to a percpu type, rather than an NR_CPUS array. At the same time, switch to only registering present CPUs, rather than using the possible CPU map. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | generic bug: use show_regs() instead of dump_stack()Heiko Carstens2007-07-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current generic bug implementation has a call to dump_stack() in case a WARN_ON(whatever) gets hit. Since report_bug(), which calls dump_stack(), gets called from an exception handler we can do better: just pass the pt_regs structure to report_bug() and pass it to show_regs() in case of a warning. This will give more debug informations like register contents, etc... In addition this avoids some pointless lines that dump_stack() emits, since it includes a stack backtrace of the exception handler which is of no interest in case of a warning. E.g. on s390 the following lines are currently always present in a stack backtrace if dump_stack() gets called from report_bug(): [<000000000001517a>] show_trace+0x92/0xe8) [<0000000000015270>] show_stack+0xa0/0xd0 [<00000000000152ce>] dump_stack+0x2e/0x3c [<0000000000195450>] report_bug+0x98/0xf8 [<0000000000016cc8>] illegal_op+0x1fc/0x21c [<00000000000227d6>] sysc_return+0x0/0x10 Acked-by: Jeremy Fitzhardinge <jeremy@goop.org> Acked-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Cc: Andi Kleen <ak@suse.de> Cc: Kyle McMartin <kyle@parisc-linux.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Paul Mundt <lethal@linux-sh.org> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | sh: Handle -ERESTART_RESTARTBLOCK for restartable syscalls.Paul Mundt2007-06-191-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation only handles -ERESTARTNOHAND, whereas we also need to handle -ERESTART_RESTARTBLOCK in the handle_signal() case for restartable system calls. As noted by Carl: This fixes the LTP test nanosleep03 - the current kernel causes -ERESTART_RESTARTBLOCK to reach user space rather than the correct -EINTR.

* | sh: oops_enter()/oops_exit() in die().Paul Mundt2007-06-181-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | As Russell helpfully pointed out on linux-arch: http://marc.info/?l=linux-arch&m=118208089204630&w=2 We were missing the oops_enter/exit() in the sh die() implementation. As we do support lockdep, it's beneficial to add these calls so lockdep properly disables itself in the die() case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | sh: Fix restartable syscall arg5 clobbering.Kaz Kojima2007-06-181-2/+4
|/ | | | | | | | | | We use R0 as the 5th argument of syscall. When the syscall restarts after signal handling, we should restore the old value of R0. The attached patch does it. Without this patch, I've experienced random failures in the situation which signals are issued frequently.
