But some small pieces of the HPPA backend still survived until

QEMU, we can nowadays safely remove the remaining HPPA parts
(like the disassembler code, or the detection of HPPA in the

The l_start and l_len fields in the various target_flock structures are
supposed to be '__kernel_off_t' or '__kernel_loff_t', which means they
should be signed, not unsigned. Correcting the structure definitions means
that __get_user() and __put_user() will correctly sign extend them if
the guest is using 32 bit offsets and the host is using 64 bit offsets.
This fixes failures in the LTP 'fcntl14' tests where it checks that
negative seek offsets work correctly.
We reindent the structures to drop hard tabs since we're touching 40%
of the fields anyway.

The siginfo_t struct includes a union. The correct way to identify
which fields of the union are relevant is complicated, because we
have to use a combination of the si_code and si_signo to figure out
which of the union's members are valid. (Within the host kernel it
is always possible to tell, but the kernel carefully avoids giving
userspace the high 16 bits of si_code, so we don't have the
information to do this the easy way...) We therefore make our best
guess, bearing in mind that a guest can spoof most of the si_codes
via rt_sigqueueinfo() if it likes. Once we have made our guess, we
record it in the top 16 bits of the si_code, so that tswap_siginfo()
later can use it. tswap_siginfo() then strips these top bits out
before writing si_code to the guest (sign-extending the lower bits).
This fixes a bug where fields were sometimes wrong; in particular
the LTP kill10 test went into an infinite loop because its signal
handler got a si_pid value of 0 rather than the pid of the sending
process.
As part of this change, we switch to using __put_user() in the
tswap_siginfo code which writes out the byteswapped values to
the target memory, in case the target memory pointer is not
sufficiently aligned for the host CPU's requirements.

Currently, __target_cmsg_nxthdr compares a pointer derived from

because pointers in the host address space and pointers in the guest

target_cmsg into __target_cmsg_nxthdr.
I found and fixed two more related bugs:
- __target_cmsg_nxthdr now returns the new cmsg pointer instead of the
old one.
- tgt_space (in host_to_target_cmsg) doesn't count "sizeof (struct

When creating a timer handle, we give the timer id a special magic offset
of 0xcafe0000. However, we never mask that offset out of the timer id before
we start using it to dereference our timer array. So we always end up aborting
timer operations because the timer id is out of bounds.
This was not an issue before my patch e52a99f756 ("linux-user: Simplify
timerid checks on g_posix_timers range") because before we would blindly mask
anything above the first 16 bits.
This patch simplifies the code around timer id creation by introducing a proper
target_timer_id typedef that is s32, just like Linux has it. It also changes the
magic offset to a value that makes all timer ids be positive.

This patch fixes the two following problems for Alpha linux-user:
- termbits.h is incorrectly using host IOC macros and structures
- IOC bitfields sizes are incorrectly set
This patch corrects the ioctl TCGETS done by isatty function call
on Alpha (when running SPEC crafty for instance).

On Alpha the target to native fcntl definitions were missing. Because of
this, programs trying to open files with the O_CREAT option were getting
O_APPEND instead, etc.
This was keeping gcc from the spec benchmarks from running, among other
things.

glibc's structs dirent and dirent64 is different from in-kernel dirent
and dirent64. Kernel headers doesn't provide structs dirent(64) any
more. So we should add it to qemu headers.
To avoid conflict with glibc it called struct linux_dirent(64).

Testing qemu-x86_64, I happen to run df and came across these mistakes
in the target_statfs/target_statfs64 structure definitions (reference:
linux/include/asm-x86/statfs.h).
