exec: add endian specific phys ld/st functions

Device code some times needs to access physical memory and does that
through the ld./st._phys functions. However, these are the exact same
functions that the CPU uses to access memory, which means they will
be endianness swapped depending on the target CPU.

However, devices don't know about the CPU's endianness, but instead
access memory directly using their own interface to the memory bus,
so they need some way to read data with their native endianness.

This patch adds _le and _be functions to ld./st._phys.

13 years agomips: rlimit incorrectly converts values

mips: rlimit incorrectly converts values

Byte swap was applied in the wrong order with testing for
RLIM_INFINITY. On mips bigendian from an amd64 system this results in
infinity being misinterpretted as 2^31-1.

This is a serious bug because it causes setrlimit stack size to kill
all child processes. This means (for example) that 'make' can run no
children. The mechanism of failure:
1. parent sets stack size rlimit to 'infinity'
2. qemu screws this value up
3. child process fetches stack size as a large (but non-infinite) value
4. qemu tries to allocate stack before execution
5. stack allocation fails (too big) and child process dies

arm-semi: Provide access to CLI arguments passed through the "-append" option

This patch basically adapts the new semi-hosting command-line support
-- introduced by Wolfgang Schildbach in the commit 2e8785ac -- for use
in system-mode.

Note that the "arm_cmdline_len" and "host_cmdline_len" variables were
renamed respectively "input_size" and "output_size" because:

    * in C, the term "length" is generally used to count the number of
      character in a string, not to count the number of bytes in a
      buffer (as it is the case here).

    * in QEMU, the term "host" is used to name variables that are in
      the host address space, not to name variables in the target
      address space (as it is the case here).

    * in the case of this system-call, the terms "input" and "output"
      fit the semantic of the official ARM semi-hosting specification
      quite well.

I know renaming can be considered harmful but I do think in this case
the semantic really matters to keep this code more understandable.
