2005-10-19[ARM] 3024/1: Add cpu_v6_proc_finTony Lindgren
Patch from Tony Lindgren Machine restart calls cpu_proc_fin() to clean and disable cache, and turn off interrupts. This patch adds proper cpu_v6_proc_fin. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-10-19powerpc: Eliminate a compile warning in signal_32.cPaul Mackerras
The second argument of get_sigset_t needed to have the const keyword. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-19powerpc: Merge machdep.hPaul Mackerras
A few things change for consistency between ppc32 and ppc64: idle functions return void; *_get_boot_time functions return unsigned long (i.e. time_t) rather than filling in a struct rtc_time (since that's useful to the callers and easier for pmac to generate); *_get_rtc_time and *_set_rtc_time functions take a struct rtc_time; irq_canonicalize is gone; nvram_sync returns void. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-19ppc: Minor smp changes for consistency with ppc64Paul Mackerras
This makes platform code use the smp_ops variable directly instead of ppc_md.smp_ops, removes the two unused `data' and `wait' arguments from the *_message_pass() functions, and removes the call to the never-implemented smp_ops->space_timers() function.

2005-10-18powerpc: change sys32_ to compat_sys_Stephen Rothwell
This allows us to get rid of one type of entry in systbl.S. In passing we remove the duplicate compat_sys_getdents and compat_sys_utimes for which there are generic versions. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-18powerpc: Fix various compile errors with ARCH=ppc, ppc64 and powerpcPaul Mackerras
This makes ppc use the syscalls.c from arch/powerpc/kernel, exports copy_and_flush from head_32.S for use by prom_init.c (ARCH=powerpc), and consolidates the sys_fadvise64_64 implementations for 32-bit. Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-17[PATCH] powerpc: Fix use of LOADBASE in merge treeDavid Gibson
The merge-tree version of LOADBASE actually loads the whole given address from the toc for ppc64. The matching OFF macro adjust for this, using an offset of 0 for ppc64, but we weren't using that in power4_idle.

2005-10-17powerpc: Initialize btext subsystem later, after prom_initPaul Mackerras
We were initializing the btext stuff from prom_init(), thus breaking the rule that all communication between prom_init() and the rest of the kernel has to be via the flattened device tree. This removes the btext initialization calls from prom_init() and initializes it instead after the device tree is unflattened. It would be nice to do it earlier, but that needs some more infrastructure to find the properties we need in the flattened device tree. Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-14[SPARC64]: Fix powering off on SMP.David S. Miller
Doing a "SUNW,stop-self" firmware call on the other cpus is not the correct thing to do when dropping into the firmware for a halt, reboot, or power-off. For now, just do nothing to quiet the other cpus, as the system should be quiescent enough. Later we may decide to implement smp_send_stop() like the other SMP platforms do. Based upon a report from Christopher Zimmermann. Signed-off-by: David S. Miller <davem@davemloft.net>

Original patch by Harald Welte, with feedback from Herbert Xu and testing by Sébastien Bernard. EBTABLES, ARP tables, and IP/IP6 tables all assume that cpus are numbered linearly.

2005-10-12[SPARC64]: Fix boot failures on SunBlade-150David S. Miller
The sequence to move over to the Linux trap tables from the firmware ones needs to be more air tight. It turns out that to be %100 safe we do need to be able to translate OBP mappings in our TLB miss handlers early. In order not to eat up a lot of kernel image memory with static page tables, just use the translations array in the OBP TLB miss handlers. That solves the bulk of the problem. Furthermore, to make sure the OBP TLB miss path will work even before the fixed MMU globals are loaded, explicitly load %g1 to TLB_SFSR at the beginning of the i-TLB and d-TLB miss handlers. To ease the OBP TLB miss walking of the prom_trans[] array, we sort it then delete all of the non-OBP entries in there (for example, there are entries for the kernel image itself which we're not interested in at all). We also save about 32K of kernel image size with this change. Not a bad side effect :-) There are still some reasons why trampoline.S can't use the setup_trap_table() yet. The most noteworthy are: 1) OBP boots secondary processors with non-bias'd stack for some reason. This is easily fixed by using a small bootup stack in the kernel image explicitly for this purpose. 2) Doing a firmware call via the normal C call prom_set_trap_table() goes through the whole OBP enter/exit sequence that saves and restores OBP and Linux kernel state in the MMUs. This path unfortunately does a "flush %g6" while loading up the OBP locked TLB entries for the firmware call. If we setup the %g6 in the trampoline.S code properly, that is in the PAGE_OFFSET linear mapping, but we're not on the kernel trap table yet so those addresses won't translate properly. One idea is to do a by-hand firmware call like we do in the early bootup code and elsewhere here in trampoline.S But this fails as well, as aparently the secondary processors are not booted with OBP's special locked TLB entries loaded. These are necessary for the firwmare to processes TLB misses correctly up until the point where we take over the trap table. This does need to be resolved at some point. Signed-off-by: David S. Miller <davem@davemloft.net>
