pbrook c276471991 The _exit syscall is used for both thread termination in NPTL applications,
and process termination in legacy applications.  Try to guess which we want
based on the presence of multiple threads.

Also implement locking when modifying the CPU list.

blueswir1 2d18e637e5 Flush stdout after printing usage()
Fixes qemu-arm|grep cpu - with _exit() getting output from qemu --help
is a bit random. Since no atexit() handlers are registered for user mode
emulation, just use exit() instead.

aurel32 d088d664f2 linux-user: identify running binary in /proc/self/exe
Some applications like to test /proc/self/exe to find
out who they are. Fake the result of readlink() for
them. Use realpath() to return full path to binary
(which the links /proc/self/exe are)

aliguori 01df040b52 x86: Debug register emulation (Jan Kiszka)
Built on top of previously enhanced breakpoint/watchpoint support, this
patch adds full debug register emulation for the x86 architecture.

Many corner cases were considered, and the result was successfully
tested inside a Linux guest with gdb, but I won't be surprised if one
or two scenarios still behave differently in reality.

p in this case is uint32_t *

e1/e2 are unsigned ints initialized from arithmetics performed on
unsigned longs

The mistake was, probably, never noticed due to the absence of any
big endian linux-user host. The types e1/e2 and p begs the quesiton
why this function takes longs at all.
