| * kbuild: use relative path to -ISam Ravnborg2006-04-042-2/+2
| | | | | | | | | | | | | | | | | | Using a relative path has the advantage that when the kernel source tree is moved the relevant .o files will not be rebuild just because the path to the kernel src has changed. This also got rid of a user of TOPDIR - which has been deprecated for a long time now. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

| * | [IA64] for_each_possible_cpu: ia64KAMEZAWA Hiroyuki2006-04-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future. This patch replaces for_each_cpu with for_each_possible_cpu under arch/ia64/kernel/.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When nolapic was passed or the local APIC was disabled for another reason ACPI would still parse the IO-APICs until these were explicitely disabled with noapic. Usually this resulted in a non booting configuration unless "nolapic noapic" was used. I also disabled the local APIC parsing in this case, although that's only cosmetic (suppresses a few printks) This hopefully makes nolapic work in all cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bugzilla Bug 6299: A pixel size of 8 bits produces wrong logo colors in x86_64. The driver has 2 methods for setting the color map, using the protected mode interface provided by the video BIOS and directly writing to the VGA registers. The former is not supported in x86_64 and the latter is enabled only in i386. Fix by enabling the latter method in x86_64 only if supported by the BIOS.

* | [PATCH] No arch-specific strpbrk implementationsKyle McMartin2006-04-1119-20/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't being exported from lib/string.c. Investigating further, I noticed a changeset that removed its export and added it to _ksyms.c on a few more architectures. The justification was that "other arches do it." I think this is wrong, since no architecture currently defines __HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it themselves. Therefore, consolidate the export to lib/string.c.

* | [PATCH] Configurable NODES_SHIFTYasunori Goto2006-04-1110-9/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.

* | [PATCH] m32r: security fix of {get,put}_user macrosHirokazu Takata2006-04-114-178/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update {get,put}_user macros for m32r kernel. - Modify get_user to use __get_user_asm macro, instead of __get_user_x macro. - Remove arch/m32r/lib/{get,put}user.S. - Some cosmetic updates. I would like to thank NIIBE Yutaka for his reporting about the m32r kernel's security problem in {get,put}_user macros. There were no address checking for user space access in {get,put}_user macros. ;-) Signed-off-by: Hirokazu Takata <takata@linux-m32r.org> Cc: NIIBE Yutaka <gniibe@fsij.org> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | [PATCH] m32r: Fix cpu_possible_map and cpu_present_map initialization for ↵Hirokazu Takata2006-04-112-16/+15Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SMP kernel This patch fixes a boot problem of the m32r SMP kernel 2.6.16-rc1-mm3 or later. In this patch, cpu_possible_map is statically initialized, and cpu_present_map is also copied from cpu_possible_map in smp_prepare_cpus(), because the m32r architecture has not supported CPU hotplug yet.

* | [PATCH] alpha: SMP boot fixesBrian Uhrain says2006-04-112-5/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've encountered two problems with 2.6.16 and newer kernels on my API CS20 (dual 833MHz Alpha 21264b processors). The first is the kernel OOPSing because of a NULL pointer dereference while trying to populate SysFS with the CPU information. The other is that only one processor was being brought up. I've included a small Alpha-specific patch that fixes both problems. The first problem was caused by the CPUs never being properly registered using register_cpu(), the way it's done on other architectures. The second problem has to do with the removal of hwrpb_cpu_present_mask in arch/alpha/kernel/smp.c. In setup_smp() in the 2.6.15 kernel sources, hwrpb_cpu_present_mask has a bit set for each processor that is probed, and afterwards cpu_present_mask is set to the cpumask for the boot CPU. In the same function of the same file in the 2.6.16 sources, instead of hwrpb_cpu_present_mask being set, cpu_possible_map is updated for each probed CPU. cpu_present_mask is still set to the cpumask of the boot CPU afterwards. The problem lies in include/asm-alpha/smp.h, where cpu_possible_map is #define'd to be cpu_present_mask. Cleanups from: Ivan Kokshaysky <ink@jurassic.park.msu.ru> - cpu_present_mask and cpu_possible_map are essentially the same thing on alpha, as it doesn't support CPU hotplug; - allocate "struct cpu" only for present CPUs, like sparc64 does. Static array of "struct cpu" is just a waste of memory.

Bohach <jzb@aexorsyst.com> found this bug: If the board has more than 32 PCI busses on it, the mptable bus array will overwrite its bounds for the PCI busses, and stomp on anything that's after it. Prevent possible table overflow and unknown data corruption. Code is in an __init section so it will be discarded after init.

* | [PATCH] swsusp: don't require bigsmpAshok Raj2006-04-111-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switching to automatic bigsmp causes a misleading error message, that more then 8 cpus are detected, and user needs to select either X86_GENERICARCH or X86_BIGSMP to handle. Reason is we switched to bigsmp to avoid IP race when new cpu is comming up. [bigsmp is nothing but using physical flat mode that can work for 1 .. 255 cpus] [default is X86_PC, that uses logical flat mode up to 8 CPUs max] Current x86_64 code uses bigsmp as default when hotplug is enabled. It would be preferable to make bigsmp as default, and work the dependencies of other related code like SMP_SUSPEND, and some related to memory hotplug code for i386. Current logical flat mode doesnt use shortcuts that cause the race by using the send_IPI_mask() instead of shortcuts when HOTPLUG_CPU is enabled. In the meantime this patch is the path of lease resistance. We will switch to bigsmp default sometime soon, when we get to work it again.

* | [PATCH] frv: define MMU mode specific syscalls as 'cond_syscall' and clean ↵Hyok S. Choi2006-04-111-16/+10Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | up unneeded macros For some architectures, a few syscalls are not linked in noMMU mode. In that case, the MMU depending syscalls are needed to be defined as 'cond_syscall'. For example, ARM architecture selectively links sys_mlock by the mode configuration. In case of FRV, it has been managed by #ifdef CONFIG_MMU macro in arch/frv/kernel/entry.S. However these conditional macros are just duplicates if they were defined as cond_syscall. Compilation test is done with FRV toolchains for both of MMU and noMMU mode. Signed-off-by: Hyok S.
