LOCAL: cvsimport make target
ARM: applied dos2unix to md5sum.S

some rebase operation are doing this which causes unclean patches. Convert
it here and now; git diff -w -b should report no changes.
gitignore: initial checkin
time: use common implementation calling gettimeofday()

Instead of providing yet another arm/__time.c file for ARM-EABI, this
patch merges existing time(2) implementations (which did all the same
thing but with different code) into one global source file.  Build of
it depends on the existence of the __NR_time symbol.

The x64_64 implementation of time.S was moved to __time.S and an empty
time.S file was added to build from the correct VPATH.
ARM: unified declaration of assembler function

Previously, specification of alignment and symbol function differed
without any reason and the symbol size was sometimes missing too.

Patch uses FUNC_START and FUNC_END macros to declare assembler
functions in a common way.
ARM-EABI: removed __unified_syscall4; it is not for ARM EABI and its semantic conflicts with __unified_syscall_swi
ARM: fixed classification of sendto() + recvfrom() syscalls

(Use number of parameters here to be prepared for further optimizations)
implement a sane nice based on getpriority and setpriority (POSIX requires nice to return the new nice value, but the syscall doesn't, so we use {set,get}priority and implement nice in libc)
seekdir/telldir: fixed prototypes

The position used by seekdir(3) and telldir(3) is of type 'long', not of
type 'off_t'.

readdir: major fixes and improvements

Depending whether getdents(2) or getdents64(2) were called, the
internal __dirstream buffer contains objects of different types:

--- fs/readdir.c ---
struct linux_dirent {
        unsigned long   d_ino;
        unsigned long   d_off;
        unsigned short  d_reclen;
        char            d_name[1];
};

SYSCALL_DEFINE3(getdents, unsigned int, fd,
                struct linux_dirent __user *, dirent, unsigned int, count)

--- include/linux/dirent.h ---
struct linux_dirent64 {
        u64             d_ino;
        s64             d_off;
        unsigned short  d_reclen;
        unsigned char   d_type;
        char            d_name[0];
};

SYSCALL_DEFINE3(getdents64, unsigned int, fd,
                struct linux_dirent64 __user *, dirent, unsigned int, count)

Existing code mixed casts between these types and even with userspace
types which causes problems when 'long' is not a 64 bit type.

The patch:

* uses correct datatypes in readdir*(3), telldir() and seekdir()

* adds a flag telling whether getdents(2) or getdents64(2) were used
  to fill dir ents buffer

* fixes prototypes of getdents64(2) and getdents(2)

* adds testsuite programs
MAKEFILE: drop $(PICODIR) dependency

libc.so will be rebuilt when something changed the $(PICODIR) which
happens e.g. when libc.so is rebuilt.

Drop this dependency; '| $(PICODIR)' is not needed because the
object files contain this already.
MAKEFILE: build some more files with EXTRACFLAGS
