powerpc applies relocations to the kcrctab.

2009-12-15module: make MODULE_SYMBOL_PREFIX into a CONFIG optionAlan Jenkins
The next commit will require the use of MODULE_SYMBOL_PREFIX in .tmp_exports-asm.S. Currently it is mixed in with C structure definitions in "asm/module.h". Move the definition of this arch option into Kconfig, so it can be easily accessed by any code. This also lets modpost.c use the same definition. Previously modpost relied on a hardcoded list of architectures in mk_elfconfig.c. A build test for blackfin, one of the two MODULE_SYMBOL_PREFIX archs, showed the generated code was unchanged. vmlinux was identical save for build ids, and an apparently randomized suffix on a single "__key" symbol in the kallsyms data).

2009-12-15ARM: unexport symbols used to implement floating point emulationAlan Jenkins
The Kconfigs for in-tree floating point emulation do not allow building as modules. That leaves the Acorn FPEmulator module. I found two public releases of this as a binary module for 2.1 and 2.2 kernels, optimized for ARMV4.[1] If there is a resurgence of interest in this, the symbols can always be re-exported. This allows the EXPORT_SYMBOL_ALIAS() hack to be removed. The ulterior motive here is that EXPORT_SYMBOL_ALIAS() makes it harder to sort the resulting kernel symbol tables. Sorted symbol tables will allow faster symbol resolution during module loading. Note that fp_send_sigs() and fp_printk() are simply aliases for existing exports and add no obvious value. Similarly fp_enter could easily be renamed to kern_fp_enter at the point of definition. Therefore removing EXPORT_SYMBOL_ALIAS will not serve as a material obstacle to re-adding the exports should they be desired in future. Build tested only.

2009-12-15ARM: use unified discard definition in linker scriptAlan Jenkins
Commit 023bf6f "linker script: unify usage of discard definition" changed the linker scripts for all architectures except for ARM. I can find no discussion about this ommision, so here are the changes for ARM. These changes are exactly parallel to the ia64 case. "ia64 is notable because it first throws away some ia64 specific subsections and then include the rest of the sections into the final image, so those sections must be discarded before the inclusion." Not boot-tested. In build testing, the modified linker script generated an identical vmlinux file. [I would like to be able to rely on this unified discard definition. I want to sort the kernel symbol tables to allow faster symbol resolution during module loading. The simplest way appears to be to generate sorted versions from vmlinux.o, link them in to vmlinux, _and discard the original unsorted tables_. This work is driven by my x86 netbook, but it is implemented at a generic level. It is possible it will benefit some ARM systems also.] Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Acked-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by-without-testing: Tejun Heo <tj@kernel.org> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-12-15x86: don't export inline functionRusty Russell
For CONFIG_PARAVIRT, load_gs_index is an inline function (it's #defined to native_load_gs_index otherwise). Exporting an inline function breaks the new assembler-based alphabetical sorted symbol list: Today's linux-next build (x86_64 allmodconfig) failed like this: .tmp_exports-asm.o: In function `__ksymtab_load_gs_index': (__ksymtab_sorted+0x5b40): undefined reference to `load_gs_index' Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> To: x86@kernel.org Cc: alan-jenkins@tuffmail.co.uk

2009-12-15Blackfin: NOMPU: skip DMA ICPLB hole when it is redundantMike Frysinger
Normally there is no user-reserved memory after the DMA region which means there is no user-reserved ICPLB coverage. So the DMA hole can be covered by the large hole that is always added to cover up to the async bank. We only need an explicit DMA whole when we also add an explicit mapping for the user-reserved memory. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-12-15Blackfin: SMP: don't start up core b until its state has been completely onlinedYi Li
When testing PREEMPT_RT kernel on BF561-EZKit, the kernel blocks while booting. When the kernel initializes the ethernet driver, it sleeps and never wakes up. The issue happens when the kernel waits for a timer for Core B to timeout (the timers are per-cpu based: static DEFINE_PER_CPU(struct tvec_base *, tvec_bases) = &boot_tvec_bases). However, the ksoftirqd thread for Core B (note, the ksoftirqd thread is also per-cpu based) cannot work properly, and the timers for Core B never times out. When ksoftirqd() for the first time runs on core B, it is possible core A is still initializing core B (see smp_init() -> cpu_up() -> __cpu_up()). So the "cpu_is_offline()" check may return true and ksoftirqd moves to "wait_to_die". So delay the core b start up until the per-cpu timers have been set up fully.

2009-12-15Blackfin: workaround anomaly 05000310Barry Song
While fetching instructions at the boundary of L1 instruction SRAM, a false External Memory Addressing Error might be triggered. We should ignore this and continue on our way to avoid random crashes. Because hardware errors are not exact in the Blackfin architecture, we need to catch a few more common cases when the code flow changes and the signal is finally delivered.

2009-12-15Blackfin: drop 4KB reserve at end of memoryBarry Song
The point of this small chunk was to avoid anomaly 05000310. This never really seemed to do what it was intended though -- no valid CPLBs exist over the reserved memory, and there is often memory before it anyways (due to the uClinux MTD and/or reserved DMA region). Plus, it doesn't address the L1 instruction case. So drop this chunk as it wastes memory and is affront to humanity.
