Aneesh Kumar K.V cc720ddb54 hw/9pfs: Abstract open state of fid to V9fsFidOpenState
To implement synthetic file system in Qemu we may not really
require file descriptor and Dir *. Make generic code use
V9fsFidOpenState instead.

M. Mohan Kumar 2c74c2cb4b hw/9pfs: Read-only support for 9p export
A new fsdev parameter "readonly" is introduced to control accessing 9p export.
"readonly" can be used to specify the access type. By default "rw" access
is given to 9p export.

Aneesh Kumar K.V 15329e8338 configure: Update configure so that open_by_handle_at check returns correct value
According to David Gibson for some compiler/libc combinations, open_by_handle_at
test in configure isn't quite right: because the file_handle pointer is never
dereferenced, gcc doesn't complain even if it is undefined. Change the test
as suggested by him.

Richard Henderson df072774cb tcg: Optimize some forms of deposit.
If the deposit replaces the entire word, optimize to a move.

If we're inserting to the top of the word, avoid the mask of arg2
as we'll be shifting out all of the garbage and shifting in zeros.

If the host is 32-bit, reduce a 64-bit deposit to a 32-bit deposit
when possible.

Stefan Weil c2f36c6ce7 exec-all: Fix void pointer arithmetic
Adding an offset to a void pointer works with gcc but is not allowed
by the current C standards. With -pedantic, gcc complains:

exec-all.h:344: error: pointer of type ‘void *’ used in arithmetic

Fix this, and also replace (unsigned long) by (uintptr_t) in the same

This reduces the size of the individual translation blocks, since
we only emit a single call for each FOP rather than three.  In

Load, store, and "create destination".  This version attempts to
change the behaviour of the translator as little as possible.  We
previously used cpu_tmp32 as the temporary destination, and we
continue to use that.  This will eventually allow a change in
representation of the fprs.

Change the name of the cpu_fpr array to make certain that all
instances are converted.

Stefan Weil f37e2a6bb3 target-sparc: Fix order of function parameters
The MinGW-w64 gcc complains about wrong parameters for
gen_helper_fpadd16_s and three other functions.

gen_helper_fpadd16_s is declared like this (hidden in lots of macros):

static inline void
 gen_helper_fpadd16s(TCGv_i32 retval, TCGv_ptr arg1,
                     TCGv_i32 arg2, TCGv_i32 arg3);

So it looks like cpu_env should be the 2nd parameter.

Please review this patch as I have no environment to test it
(maybe the 1st parameter should be cpu_dst?).
