2008-04-30Basic braille screen reader supportSamuel Thibault
This adds a minimalistic braille screen reader support. This is meant to be used by blind people e.g. on boot failures or when / cannot be mounted etc and thus the userland screen readers can not work.

2008-04-29iomap: fix 64 bits resources on 32 bitsBenjamin Herrenschmidt
Almost all implementations of pci_iomap() in the kernel, including the generic lib/iomap.c one, copies the content of a struct resource into unsigned long's which will break on 32 bits platforms with 64 bits resources. This fixes all definitions of pci_iomap() to use resource_size_t. I also "fixed" the 64bits arch for consistency.

2008-04-24[POWERPC] Add strncmp to arch/ppcJosh Boyer
Commit 0119536cd314ef95553604208c25bc35581f7f0a added an assembly version of strncmp to PowerPC. However, it changed a common header file between arch/ppc and arch/powerpc without adding strncmp to arch/ppc. This fixes that omission so that arch/ppc links again.

2008-02-08CONFIG_HIGHPTE vs. sub-page page tables.Martin Schwidefsky
Background: I've implemented 1K/2K page tables for s390. These sub-page page tables are required to properly support the s390 virtualization instruction with KVM. The SIE instruction requires that the page tables have 256 page table entries (pte) followed by 256 page status table entries (pgste). The pgstes are only required if the process is using the SIE instruction. The pgstes are updated by the hardware and by the hypervisor for a number of reasons, one of them is dirty and reference bit tracking. To avoid wasting memory the standard pte table allocation should return 1K/2K (31/64 bit) and 2K/4K if the process is using SIE. Problem: Page size on s390 is 4K, page table size is 1K or 2K. That means the s390 version for pte_alloc_one cannot return a pointer to a struct page. Trouble is that with the CONFIG_HIGHPTE feature on x86 pte_alloc_one cannot return a pointer to a pte either, since that would require more than 32 bit for the return value of pte_alloc_one (and the pte * would not be accessible since its not kmapped). Solution: The only solution I found to this dilemma is a new typedef: a pgtable_t. For s390 pgtable_t will be a (pte *) - to be introduced with a later patch. For everybody else it will be a (struct page *). The additional problem with the initialization of the ptl lock and the NR_PAGETABLE accounting is solved with a constructor pgtable_page_ctor and a destructor pgtable_page_dtor. The page table allocation and free functions need to call these two whenever a page table page is allocated or freed. pmd_populate will get a pgtable_t instead of a struct page pointer. To get the pgtable_t back from a pmd entry that has been installed with pmd_populate a new function pmd_pgtable is added. It replaces the pmd_page call in free_pte_range and apply_to_pte_range.

2008-02-06remove support for un-needed _extratext sectionRobin Getz
When passing a zero address to kallsyms_lookup(), the kernel thought it was a valid kernel address, even if it is not. This is because is_ksym_addr() called is_kernel_extratext() and checked against labels that don't exist on many archs (which default as zero). Since PPC was the only kernel which defines _extra_text, (in 2005), and no longer needs it, this patch removes _extra_text support.

2008-02-03Add HAVE_KPROBESMathieu Desnoyers
Linus: On the per-architecture side, I do think it would be better to *not* have internal architecture knowledge in a generic file, and as such a line like depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32 really shouldn't exist in a file like kernel/Kconfig.instrumentation. It would be much better to do depends on ARCH_SUPPORTS_KPROBES in that generic file, and then architectures that do support it would just have a bool ARCH_SUPPORTS_KPROBES default y in *their* architecture files. That would seem to be much more logical, and is readable both for arch maintainers *and* for people who have no clue - and don't care - about which architecture is supposed to support which interface... Changelog: Actually, I know I gave this as the magic incantation, but now that I see it, I realize that I should have told you to just use config KPROBES_SUPPORT def_bool y instead, which is a bit denser. We seem to use both kinds of syntax for these things, but this is really what "def_bool" is there for... - Use HAVE_KPROBES - Use a select - Yet another update : Moving to HAVE_* now. - Update ARM for kprobes support.

2008-02-03Add HAVE_OPROFILEMathieu Desnoyers
Linus: On the per-architecture side, I do think it would be better to *not* have internal architecture knowledge in a generic file, and as such a line like depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32 really shouldn't exist in a file like kernel/Kconfig.instrumentation. It would be much better to do depends on ARCH_SUPPORTS_KPROBES in that generic file, and then architectures that do support it would just have a bool ARCH_SUPPORTS_KPROBES default y in *their* architecture files. That would seem to be much more logical, and is readable both for arch maintainers *and* for people who have no clue - and don't care - about which architecture is supposed to support which interface... Changelog: Actually, I know I gave this as the magic incantation, but now that I see it, I realize that I should have told you to just use config ARCH_SUPPORTS_KPROBES def_bool y instead, which is a bit denser. We seem to use both kinds of syntax for these things, but this is really what "def_bool" is there for... Changelog : - Moving to HAVE_*. - Add AVR32 oprofile.

2008-01-28[netdrvr] irq handler minor cleanups in several driversJeff Garzik
* use irq_handler_t where appropriate * no need to use 'irq' function arg, its already stored in a data struct * rename irq handler 'irq' argument to 'dummy', where the function has been analyzed and proven not to use its first argument. * remove always-false "dev_id == NULL" test from irq handlers * remove pointless casts from void* * declance: irq argument is not const * add KERN_xxx printk prefix * fix minor whitespace weirdness Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-01-28all archs: consolidate init and exit sections in vmlinux.lds.hSam Ravnborg
