* [PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman2007-02-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

* [IA64] Fix NULL-pointer dereference in ia64_machine_kexec()Bernhard Walle2007-02-051-0/+5
| | | | | | | | | | | | | | | This patch fixes a NULL-pointer dereference in ia64_machine_kexec(). The variable ia64_kimage is set in machine_kexec_prepare() which is called from sys_kexec_load(). If kdump wasn't configured before, ia64_kimage is NULL. machine_kdump_on_init() passes ia64_kimage() to machine_kexec() which assumes a valid value. The patch also adds a few sanity checks for the image to simplify debugging of similar problems in future.

* [IA64] CONFIG_KEXEC/CONFIG_CRASH_DUMP permutationsHorms2006-12-121-22/+0
| | | | | | | | | | | | | | | | | | Actually, on reflection I think that there is a good case for keeping the options separate. I am thinking particularly of people who want a very small crashdump kernel and thus don't want to compile in kexec. The patch below should fix things up so that all valid combinations of KEXEC, CRASH_DUMP and VMCORE compile cleanly - VMCORE depends on CRASH_DUMP which is why I said valid combinations. In a nutshell it just untangles unrelated code and switches around a few defines. Please note that it creats a new file, arch/ia64/kernel/crash_dump.c This is in keeping with the i386 implementation.
