2005-09-11kbuild: rename prepare to archprepare to fix dependency chainSam Ravnborg
When introducing the generic asm-offsets.h support the dependency chain for the prepare targets was changed. All build scripts expecting include/asm/asm-offsets.h to be made when using the prepare target would broke. With the limited number of prepare targets left in arch Makefiles the trivial solution was to introduce a new arch specific target: archprepare The dependency chain looks like this now: prepare | +--> prepare0 | +--> archprepare | +--> scripts_basic +--> prepare1 | +---> prepare2 | +--> prepare3 So prepare 3 is processed before prepare2 etc. This guaantees that the asm symlink, version.h, scripts_basic are all updated before archprepare is processed. prepare0 which build the asm-offsets.h file will need the actions performed by archprepare. The head target is now named prepare, because users scripts will most likely use that target, but prepare-all has been kept for compatibility. Updated Documentation/kbuild/makefiles.txt.

2005-09-10[PATCH] Remove even more stale references to Documentation/smp.texArthur Othieno
Randy cleaned out the bulk of these stale references to the now long gone Documentation/smp.tex back in 2004. I followed this up with a few more sweeps. Somehow, these have managed to sneak back in since. I can't seem to figure out a contact point for M32R (no one listed in MAINTAINERS!), but, these patches are only but trivial.

2005-09-07[PATCH] Kconfig fix (BLK_DEV_FD dependencies)viro@ZenIV.linux.org.uk
Sanitized and fixed floppy dependencies: split the messy dependencies for BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making BLK_DEV_FD depend on that one and taking declarations of ARCH_MAY_HAVE_PC_FDC to arch/*/Kconfig. While we are at it, fixed several obvious cases when BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h are *not* going to have floppy.c compile, let alone work). If you can come up with better name for that ("this architecture might have working PC-compatible floppy disk controller"), you are more than welcome - just s/ARCH_MAY_HAVE_PC_FDC/your_prefered_name/g in the patch below...

2005-09-07[ARM] 2871/1: Fixes an issue with gettimeofday not working correctly on ↵Adam Brooks
Intel IOP3xx processors Patch from Adam Brooks The current gettimeofday implementation for the IOP3xx processors reads the contents of the timer interrupt register and does math on the value to figure out exactly what time it is. To do this it multiplies the contents of the timer register with a large constant. The result is then divided by a large constant. Unfortunately the result of the first multiplication is often too large for the register to hold. The solution is to combine the two large constants to a single smaller constant at compile time. Then the timer value can be divided by single smaller constant without any overflow issues.

2005-09-01[ARM] 2865/2: fix fadvise64_64 syscall argument passingNicolas Pitre
Patch from Nicolas Pitre The prototype for sys_fadvise64_64() is: long sys_fadvise64_64(int fd, loff_t offset, loff_t len, int advice) The argument list is therefore as follows on legacy ABI: fd: type int (r0) offset: type long long (r1-r2) len: type long long (r3-sp[0]) advice: type int (sp[4]) With EABI this becomes: fd: type int (r0) offset: type long long (r2-r3) len: type long long (sp[0]-sp[4]) advice: type int (sp[8]) Not only do we have ABI differences here, but the EABI version requires one additional word on the syscall stack. To avoid the ABI mismatch and the extra stack space required with EABI this syscall is now defined with a different argument ordering on ARM as follows: long sys_arm_fadvise64_64(int fd, int advice, loff_t offset, loff_t len) This gives us the following ABI independent argument distribution: fd: type int (r0) advice: type int (r1) offset: type long long (r2-r3) len: type long long (sp[0]-sp[4]) Now, since the syscall entry code takes care of 5 registers only by default including the store of r4 to the stack, we need a wrapper to store r5 to the stack as well. Because that wrapper was missing and was always required this means that sys_fadvise64_64 never worked on ARM and therefore we can safely reuse its syscall number for our new sys_arm_fadvise64_64 interface.

2005-08-29[ARM] 2853/1: Make alloc_init_supersection() work with 36-bit mappingsDeepak Saxena
Patch from Deepak Saxena Working on adding support for 36-bit static mappings for ARMv6 and Intel's XSC3 core and noticed that alloc_init_supersection currently increments the phys addr by 1MB on each of the 16 iterations and then forces alignment to supersection size (16MB). This is really uneeded b/c we have already forced the phys address to be 16MB aligned in create_mapping(). Furthermore, this breaks 36-bit addressing b/c bits [23:20] of the PMD contain bits [35:32] of the physical address and the masking causes us to loose those bits thus ending up with an incorrect virt -> phys translation. The other option is to have an alloc_init_supersection36. Tested on Intel IXP2350 CPU with 36-bit static I/O mappings.
