- Started overhauling the syscalls to account for different architectures; in particular, accounts for the fact that the __NR_foo syscall number often doesn't directly match with the sys_foo() function that implements the function in the Linux kernel. So started introducing this indirection as needed. Currently, only read() and write() have been done; the transition will be staged, since doing all syscalls in one hit is a total pain. This will also pave the way for scalar syscall arg checking with Memcheck, now that it is clear what the prototypes of the relevant syscalls are. - Removed support for 2.2 kernels in the configure test, after discussion with Julian. If it causes major problems, we can consider reverting. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2948
