2799 5981 d 1 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5989 d 18 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2785 5990 d 11 h jermar /trunk/uspace/app/tester/ Finish run_safe_tests() in app/tester (contributed by Tim Post).  
2784 5997 d 13 h jermar /trunk/kernel/arch/ Fortify ia32 and amd64 kernels against mallicious uspace applications that set
DF prior to entering the kernel. For AMD64 syscalls, we don't use the CLD
instruction, but make use of the SFMASK MSR instead. Simics works fine with
it, but QEMU seems to have a problem.
