2009-06-16kmap_types: make most arches use generic header fileRandy Dunlap1-21/+3
Convert most arches to use asm-generic/kmap_types.h. Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h, controlled by __WITH_KM_FENCE from each arch's kmap_types.h file. Would be nice to be able to add custom KM_types per arch, but I don't yet see a nice, clean way to do that. Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and 68k(tonyb). Note: avr32 should be able to remove KM_PTE2 (since it's not used) and then just use the generic kmap_types.h file. Get avr32 maintainer approval.

2009-06-16mm: consolidate init_mm definitionAlexey Dobriyan1-4/+0
* create mm/init-mm.c, move init_mm there * remove INIT_MM, initialize init_mm with C99 initializer * unexport init_mm on all arches: init_mm is already unexported on x86. One strange place is some OMAP driver (drivers/video/omap/) which won't build modular, but it's already wants get_vm_area() export. Somebody should look there.

2009-06-11asm-generic: introduce asm/bitsperlong.hArnd Bergmann2-8/+20
This provides a reliable way for asm-generic/types.h and other files to find out if it is running on a 32 or 64 bit platform. We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.

2009-03-31parisc: expose 32/64-bit capabilities in cpuinfoColin Watson3-1/+14
It'd be rather useful for debian-installer if we could get hold of accurate firmware information on whether only 32-bit kernels are supported, only 64-bit kernels, or both; this would allow us to present an accurate menu of kernel packages if more than one is available, rather than the user having to guess. This patch attempts to expose it in cpuinfo. I adjusted pdc_model_capabilities to cope with a potential PDC_INVALID_ARG return as the firmware manual instructs, by assuming 32-bit only. This may be the wrong place for it. I made up user-visible capability names by total fiat and for the moment ignored the other bits that may appear in the capabilities word. I have no PA-RISC machine myself to test on, and no PA experience either, so I rather hope that somebody will kind-heartedly take this and fix it up if needed. I ran it past Dann Frazier on IRC and he said "looks good to me", but I think without testing. Also, this is against the Ubuntu 2.6.28 kernel tree since that's what I had handy and I was a bit tight on disk space to slurp down another tree. Sorry if it's skewed in any relevant way; I'll be happy to adjust if necessary. Thanks in advance! Signed-off-by: Colin Watson <cjwatson@canonical.com> Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
2009-03-31parisc: use constants instead of numbers in assemblyHelge Deller1-4/+4
A few small fixups: * _PAGE_SIZE_ENCODING_DEFAULT is wrong here, as one might assume that it's possible to define the page size that way. This is wrong. Use 0 instead. * use constants instead of hardcoded numerical values in depi and extru while building the PFN out of the pte entry * use SHRREG instead of extru (iitlba expects the PFN at bits {7..26}) Still wondering why we can use the same register (pte) as extru source and target register, but it seems to work on PA1.1 and PA2.0...

2009-03-31parisc: fix usage of 32bit PTE page table entries on 32bit kernelsHelge Deller3-16/+19
This patch fixes a long outstanding bug on 32bit parisc linux kernels which prevented us from using 32bit PTE table entries (instead of 64bit entries of which 32bit were unused). The problem was caused by this assembler statement in the L2_ptep macro in arch/parisc/kernel/entry.S:447: EXTR \va,31-ASM_PGDIR_SHIFT,ASM_BITS_PER_PGD,\index which expanded to extrw,u r8,9,11,r1 and which has undefined behavior since the length value (11) extends beyond the leftmost bit (11-1 > 9). Interestingly PA2.0 processors seem to don't care and just zero-extend the value, while PA1.1 processors don't. Fix this problem by detecting an address space overflow with ASM_BITS_PER_PGD and adjusting it accordingly. To prevent such problems in the future, some compile time sanity checks in arch/parisc/mm/init.c were added. Since the page table now only consumes half of it's old size, we can use the freed memory to harmonize 32- and 64bit kernels and let both map 16MB for the initial page table.

Due to a different size of ino_t ustat needs a compat handler, but currently only x86 and mips provide one. Add a generic compat_sys_ustat and switch all architectures over to it. Instead of doing various user copy hacks compat_sys_ustat just reimplements sys_ustat as it's trivial. This was suggested by Arnd Bergmann.

We also take the chance to change send_IPI_mask() and use the new for_each_cpu() iterator. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
