* ftrace: rename FTRACE to FUNCTION_TRACERSteven Rostedt2008-10-20
| | | | | | | | | | | | Due to confusion between the ftrace infrastructure and the gcc profiling tracer "ftrace", this patch renames the config options from FTRACE to FUNCTION_TRACER. The other two names that are offspring from FTRACE DYNAMIC_FTRACE and FTRACE_MCOUNT_RECORD will stay the same. This patch was generated mostly by script, and partially by hand.

* [ARM] 5229/3: Replace some ARMv7 opcodes with the instruction nameCatalin Marinas2008-10-03
| | | | | | | | | These instructions were placed in the code directly as opcodes because early compilers didn't support them.

* inflate: refactor inflate malloc codeThomas Petazzoni2008-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inflate requires some dynamic memory allocation very early in the boot process and this is provided with a set of four functions: malloc/free/gzip_mark/gzip_release. The old inflate code used a mark/release strategy rather than implement free. This new version instead keeps a count on the number of outstanding allocations and when it hits zero, it resets the malloc arena. This allows removing all the mark and release implementations and unifying all the malloc/free implementations. The architecture-dependent code must define two addresses: - free_mem_ptr, the address of the beginning of the area in which allocations should be made - free_mem_end_ptr, the address of the end of the area in which allocations should be made. If set to 0, then no check is made on the number of allocations, it just grows as much as needed The architecture-dependent code can also provide an arch_decomp_wdog() function call. This function will be called several times during the decompression process, and allow to notify the watchdog that the system is still running. If an architecture provides such a call, then it must define ARCH_HAS_DECOMP_WDOG so that the generic inflate code calls arch_decomp_wdog(). Work initially done by Matt Mackall, updated to a recent version of the kernel and improved by me.

| | | | | | | | | | | | | | | | | | | | | | | | | | The cache replacement policy on the Feroceon core doesn't guarantee that reading through a linear chunk of memory flushes the entire cache.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default ARMv4 method consisting of reading through some memory area isn't compatible with the cache replacement policy of some ARMv5TEJ compatible cache implementations. It is also a bit wasteful when a dedicated instruction can do the needed work optimally. It is hard to tell if all ARMv5TEJ cores will support the used CP15 instruction, but at least all those implementations Linux currently knows about (ARM926 and ARM1026) do support it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

* [ARM] 3809/3: get rid of 4 megabyte kernel image size limitLennert Buytenhek2006-09-30
| | | | | | | | | | | | | | | | | | | | | We currently have a hardcoded 4 megabyte uncompressed kernel image size limit, which is easily exceeded by, for example, enabling some of the various kernel debugging options. When setting up the initial page tables (which is where this 4M limit is hardcoded), it's actually relatively easy to find out the true size of the uncompressed kernel image and create enough page table entries for things to fit, so this patch makes it so. In the decompressor, we also need to know the size of the uncompressed kernel image, to figure out whether there is any chance that uncompressing the kernel might overwrite the compressed kernel image stored elsewhere in memory. We don't have that info at this boot stage, though, so we approximate the size of the uncompressed kernel by taking the compressed kernel image size and allowing for a maximum 4x expansion.
