2013-03-14Add support for the Meta architectureMarkos Chandras
Meta cores are 32-bit, hardware multithreaded, general purpose, embedded processors which also feature a DSP instruction set, and can be found in many digital radios. They are capable of running different operating systems on different hardware threads, for example a digital radio might run RTOSes for DAB decoding and audio decoding on 3 hardware threads, and run Linux on the 4th hardware thread to manage the user interface, networking etc. HTPs are also capable of running SMP Linux on multiple hardware threads.

2013-03-14leek: if lseek syscall is not available, use lseek64 even for !LFSVineet Gupta
With Busybox and uClibc - both built w/o LFS, this caused ash to be completely broken, as lseek was simply returning error. Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Markos Chandras <markos.chandras@imgtec.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2013-03-14utimes: Export utimensat based utimesVineet Gupta
sys/time.h has libc_hidden_proto(utimes) which generates the hidden "__GI_utimes" symbol reference, and common/utimes.c has a libc_hidden_def(utimes) which generates the exported "utimes" alias. As part of no-legacy-syscall kernel ABI, Commit 80dc2ed05 "utimes: Use utimensat if arch does not have the utimes syscall" introduced a new wrapper, but missed the corresponding libc_hidden_def, causing Busybox (1.20.0) link to fail (for ARC). Also don't generate a STUB, in that case. ---------------->8------------------- .... touch.c:(.text.touch_main+0xdc): undefined reference to `utimes' touch.c:(.text.touch_main+0x114): undefined reference to `utimes' libbb/lib.a(copy_file.o): In function `copy_file': copy_file.c:(.text.copy_file+0x446): undefined reference to `utimes' collect2: ld returned 1 exit status ---------------->8------------------- Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Markos Chandras <markos.chandras@imgtec.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2013-02-20nice: fix overflow checking in int_add_no_wrap()Xi Wang
In C, signed integer overflow is undefined behavior. Many compilers optimize away checks like `a + b < a'. Use safe precondition testing instead. Signed-off-by: Xi Wang <xi@mit.edu> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2013-02-20fstatfs: Add __libc_fstatfs wrapperMarkos Chandras
New architectures don't have fstatfs anymore, so we use a wrapper for __libc_fstatfs which will use fstatfs64 internally. The interface however needs to remain the same (i.e accepting a struct statfs as a second argument) for backwards compatibility Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
