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).

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.

Commit 023bf6f1 "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>

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

* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-udf-2.6: udf: Avoid IO in udf_clear_inode udf: Try harder when looking for VAT inode udf: Fix compilation with UDFFS_DEBUG enabled
-
Jan Kara authored
It is not very good to do IO in udf_clear_inode. First, VFS does not really expect inode to become dirty there and thus we have to write it ourselves, second, memory reclaim gets blocked waiting for IO when it does not really expect it, third, the IO pattern (e.g. on umount) resulting from writes in udf_clear_inode is bad and it slows down writing a lot. The reason why UDF needed to do IO in udf_clear_inode is that UDF standard mandates extent length to exactly match inode size. But when we allocate extents to a file or directory, we don't really know what exactly the final file size will be and thus temporarily set it to block boundary and later truncate it to exact length in udf_clear_inode. Now, this is changed to truncate to final file size in udf_release_file for regular files. For directories and symlinks, we do the truncation at the moment when learn what the final file size will be. Signed-off-by: Jan Kara <jack@suse.cz>

Some disks do not contain VAT inode in the last recorded block as required by the standard but a few blocks earlier (or the number of recorded blocks is wrong). So look for the VAT inode a bit before the end of the media. Signed-off-by: Jan Kara <jack@suse.cz>

Add check if APIC is not disabled since thermal monitoring depends on it. As only apic gets disabled we should not try to install "thermal monitor" vector, print out that thermal monitoring is enabled and etc... Note that "Intel Correct Machine Check Interrupts" already has such a check. Also I decided to not add cpu_has_apic check into mcheck_intel_therm_init since even if it'll call apic_read on disabled apic -- it's safe here and allow us to save a few code bytes.

They can allocate aperture by hand and use GART. - GART systems without GAP must disable GART on shutdown. - swiotlb usage is forced by the boot option, gart_iommu_hole_init() is not called, so we disable GART early_gart_iommu_check().
