[IA64] fix compile failure with non modular builds

2008-09-10T17:46:32Z

Broke the non modular builds by moving an essential function into modules.c. Fix this by moving it out again and into asm/sections.h as an inline. To do this, the definitions of struct fdesc and struct got_val have been lifted out of modules.c and put in asm/elf.h where they belong. Signed-off-by: James Bottomley Signed-off-by: Tony Luck

lib: Correct printk %pF to work on all architectures

2008-09-09T18:51:15Z

It was introduced by "vsprintf: add support for '%pS' and '%pF' pointer formats" in commit 0fe1ef24f7bd0020f29ffe287dfdb9ead33ca0b2. However, the current way its coded doesn't work on parisc64. For two reasons: 1) parisc isn't in the #ifdef and 2) parisc has a different format for function descriptors Make dereference_function_descriptor() more accommodating by allowing architecture overrides. I put the three overrides (for parisc64, ppc64 and ia64) in arch/kernel/module.c because that's where the kernel internal linker which knows how to deal with function descriptors sits.

[IA64] adding parameter check to module_free()

2008-07-17T18:22:01Z

module_free() refers the first parameter before checking. But it is called like below(in kernel/kprobes). The first parameter is always NULL. This happens when many probe points(>1024) are set by kprobes. I encountered this with using SystemTap. It can set many probes easily. static int __kprobes collect_one_slot(struct kprobe_insn_page *kip, int idx) { ... if (kip->nused == 0) { hlist_del(&kip->hlist); if (hlist_empty(&kprobe_insn_pages)) { ... } else { module_free(NULL, kip->insns); //<<< 1st param always NULL kfree(kip); } return 1; } return 0; } Signed-off-by: Akiyama, Nobuyuki Signed-off-by: Tony Luck

[IA64] remove remaining FUNCTION occurrences

__FUNCTION__ is gcc-specific, use __func__ Long lines have been kept where they exist, some small spacing changes have been done. Signed-off-by: Harvey Harrison Signed-off-by: Andrew Morton Signed-off-by: Tony Luck

modules: fold percpu_modcopy into module.c

2008-01-30T22:27:58Z

percpu_modcopy() is defined multiple times in arch files. However, the only user is module.c. Put a static definition into module.c and remove the definitions from the arch files. Signed-off-by: Ingo Molnar

percpu: make the asm-generic/percpu.h more "generic"

2008-01-30T12:32:52Z

- add support for PER_CPU_ATTRIBUTES - fix generic smp percpu_modcopy to use per_cpu_offset() macro. Add the ability to use generic/percpu even if the arch needs to override several aspects of its operations. This will enable the use of generic percpu.h for all arches. An arch may define: __per_cpu_offset Do not use the generic pointer array. Arch must define per_cpu_offset(cpu) (used by x86_64, s390). __my_cpu_offset Can be defined to provide an optimized way to determine the offset for variables of the currently executing processor. Used by ia64, x86_64, x86_32, sparc64, s/390. SHIFT_PTR(ptr, offset) If an arch defines it then special handling of pointer arithmentic may be implemented. Used by s/390. (Some of these special percpu arch implementations may be later consolidated so that there are less cases to deal with.)

[IA64] for_each_possible_cpu: ia64

2006-04-06T22:03:49Z

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/.

[IA64] wider use of for_each_cpu_mask() in arch/ia64

2005-10-25T22:10:08Z

In arch/ia64 change the explicit use of for-loops and NR_CPUS into the general for_each_cpu() or for_each_online_cpu() constructs, as appropriate. This widens the scope of potential future optimizations of the general constructs, as well as takes advantage of the existing optimizations of first_cpu() and next_cpu().
