* [MIPS] Get rid of __ilog2Ralf Baechle2008-05-121-7/+2
| | | | | | | | 56a6b1eb7bfb5ace0b5cb9c149f502fbd101b8ab was a bit too conservative and left __ilog2 around which is only used as an internal function for other bitops. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* [MIPS] Fix __fls for non-MIPS32/MIPS64 cpusThomas Bogendoerfer2008-05-121-2/+3
| | | | | | | | | Only MIPS32 and MIPS64 CPUs implement clz/dclz. Therefore don't export __ilog2() for non MIPS32/MIPS64 cpus and use generic __fls bitop code for these cpus. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

In addition to these changes, also do the following: - mention DBAu1200 board in the Makefile; - replace the group of #include/#ifdef directives by a single #include <au1xxx.h> since this header contains the needed stuff; - properly indent the blocks; - insert spaces between operator and its operands, remove excess spaces there; - remove needless parentheses and add some for clarity; - replace numeric literals/expressions with the matching macros; - remove space after the type cast's closing parenthesis; - reduce pb1200_setup_cascade() to the single 'return' statement; - reduce the number of printed empty lines in the so-called CPLD workaround; - remove #undef AU1X00_EXTERNAL_INT since that macro is not defined anywhere; - replace spaces after the macro name with tabs in the #define directives; - remove excess tabs after the macro name in the #define directives; - fix typo in the BCSR_RESETS_PWMR1mUX macro's name; - group all Pb1200 PCMCIA definitions together; - put the function's result type and name/parameters on the same line; - insert missing and remove excess new lines; - make the multi-line comment style consistent with the kernel style elsewhere by adding empty first line and/or adding space/asterisk on their left side; - fix typos/errors, capitalize acronyms, etc. in the comments; - combine some comments; - update MontaVista copyright; - remove Pete Popov's old email address...

| | | | | | | | | | | | | | | | | | | | | Rename div64_64 to div64_u64 to make it consistent with the other divide functions, so it clearly includes the type of the divide. Move its definition to math64.h as currently no architecture overrides the generic implementation. They can still override it of course, but the duplicated declarations are avoided.

| * [MIPS] Pb1200/DBAu1200: move platform code to its proper placeSergei Shtylyov2008-04-282-18/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since both the IDE interface and SMC 91C111 Ethernet chip are on-board devices, not SOC devices, move the platform device registration form the common to the board specific code. While at it, remove semicolon (which didn't break compilation only by chance) from the AU1XXX_ATA_DDMA_REQ macro and do some renaming: - change 'au1200_ide0_' variable name prefix to the mere 'ide_'; - change 'smc91x_' variable name prefix to 'smc91c111_' since that's the name of the chip used on the boards; - drop 'AU1XXX_' prefix from the names of macros describing IDE and Ethernet on-board devices; - change 'SMC91111_' to 'SMC91C111_', change 'IRQ' to 'INT' in the names of the macros describing the Ethernet chip for consistency with the IDE macros; - change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is indeed a shift count) in the names of the macros describing the IDE interface.

* | mm: introduce pte_special pte bitNick Piggin2008-04-281-0/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | s390 for one, cannot implement VM_MIXEDMAP with pfn_valid, due to their memory model (which is more dynamic than most). Instead, they had proposed to implement it with an additional path through vm_normal_page(), using a bit in the pte to determine whether or not the page should be refcounted: vm_normal_page() { ... if (unlikely(vma->vm_flags & (VM_PFNMAP|VM_MIXEDMAP))) { if (vma->vm_flags & VM_MIXEDMAP) { #ifdef s390 if (!mixedmap_refcount_pte(pte)) return NULL; #else if (!pfn_valid(pfn)) return NULL; #endif goto out; } ... } This is fine, however if we are allowed to use a bit in the pte to determine refcountedness, we can use that to _completely_ replace all the vma based schemes. So instead of adding more cases to the already complex vma-based scheme, we can have a clearly seperate and simple pte-based scheme (and get slightly better code generation in the process): vm_normal_page() { #ifdef s390 if (!mixedmap_refcount_pte(pte)) return NULL; return pte_page(pte); #else ... #endif } And finally, we may rather make this concept usable by any architecture rather than making it s390 only, so implement a new type of pte state for this. Unfortunately the old vma based code must stay, because some architectures may not be able to spare pte bits. This makes vm_normal_page a little bit more ugly than we would like, but the 2 cases are clearly seperate. So introduce a pte_special pte state, and use it in mm/memory.c. It is currently a noop for all architectures, so this doesn't actually result in any compiled code changes to mm/memory.o. BTW: I haven't put vm_normal_page() into arch code as-per an earlier suggestion. The reason is that, regardless of where vm_normal_page is actually implemented, the *abstraction* is still exactly the same. Also, while it depends on whether the architecture has pte_special or not, that is the only two possible cases, and it really isn't an arch specific function -- the role of the arch code should be to provide primitive functions and accessors with which to build the core code; pte_special does that. We do not want architectures to know or care about vm_normal_page itself, and we definitely don't want them being able to invent something new there out of sight of mm/ code. If we made vm_normal_page an arch function, then we have to make vm_insert_mixed (next patch) an arch function too. So I don't think moving it to arch code fundamentally improves any abstractions, while it does practically make the code more difficult to follow, for both mm and arch developers, and easier to misuse.

Added __fls(x) = fls64(x) - 1. ia64 has fls, but not __fls. Added __fls based on code of fls. mips and powerpc have __ilog2, which is the same as __fls. Added __fls = __ilog2. parisc, s390, sh and sparc64: Include generic __fls. x86_64 already has __fls.
