2007-10-14kbuild: enable 'make CFLAGS=...' to add additional options to CCSam Ravnborg1-1/+1
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.

2007-10-11[MIPS] VPE: reimplement ELF loader.Ralf Baechle1-34/+11
Loading ELF binaries based on the section table is totally wrong. This still leaves the other fat bug of referencing symbols in an executable unfixed, so people better don't run strip on their binaries ... As added bonus the new loader is also 23 lines shorter.

2007-10-11[MIPS] Make facility to convert CPU types to strings generally available.Ralf Baechle3-77/+94
So far /proc/cpuinfo has been the only user but human readable processor name are more useful than that for proc. Signed-off-by: Ralf Baechle <[email protected]>

2007-10-11[MIPS] Allow hardwiring of the CPU type to a single type for optimization.Ralf Baechle1-3/+3
This saves a few k on systems which only ever ship with a single CPU type. Signed-off-by: Ralf Baechle <[email protected]>
2007-10-11[MIPS] i8253 PIT clocksource and clockevent driversRalf Baechle2-0/+214
Derived from the i386 variant with a few x86 complexities chopped off. Signed-off-by: Ralf Baechle <[email protected]>
2007-10-11[MIPS] Dyntick support for SMTC:Ralf Baechle2-48/+130
The kernel currently only supports broadcasting of the timer interrupt from a single timer, not multicasting into two multicast groups of processors. So the implemented mechanism for SMTC works by broadcasting the cp0 compare interrupt on VPE 0 and ignoring it on any additional VPEs. Signed-off-by: Ralf Baechle <[email protected]>

2007-10-11[MIPS] Switch from to_tm to rtc_time_to_tmRalf Baechle1-49/+0
This replaces the MIPS-specific to_tm function with the generic rtc_time_to_tm function. The big difference between the two functions is that rtc_time_to_tm uses epoch 70 while to_tm uses 1970, so the result of rtc_time_to_tm needs to be fixed up. Signed-off-by: Ralf Baechle <[email protected]>
2007-10-11[MIPS] Deforest the function pointer jungle in the time code.Ralf Baechle1-31/+14
Hard to follow who is pointing what to where and why so it's simply getting in the way of the time code renovation. Signed-off-by: Ralf Baechle <[email protected]>

2007-10-11[MIPS] Sibyte: Replace SB1 cachecode with standard R4000 class cache code.Ralf Baechle2-8/+6
It may not be perfect yet but the SB1 code is badly borken and has horrible performance issues. Downside: This seriously breaks support for pass 1 parts of the BCM1250 where indexed cacheops don't work quite reliable but I seem to be the last one on the planet with a pass 1 part anyway.
