parisc: avoid undefined shift in cnv_float.h

2013-01-07T22:06:22+00:00

The attached change fixes a float conversion problem found running the
GCC testsuite with GCC configured with --with-arch=2.0.

The actual problem occurs for an exponent value of 63. This is the
maximum exponent value that can be passed. This causes a left shift by
32 in the else hunk of the macro. This causes undefined behavior and the
wrong value is returned for dresultB. The fix is the check "exponent <=
62". If the exponent is 63, dresultB is set to 0. The patch also
optimizes the operation a bit by copying "Sall(sgl_value) <<
SGL_EXP_LENGTH" to val, so that sgl_value is not modified.

bug.h: add include of it to various implicit C users

2012-02-29T22:15:08+00:00

With bug.h currently living right in linux/kernel.h there
are files that use BUG_ON and friends but are not including
the header explicitly.  Fix them up so we can remove the
presence in kernel.h file.

treewide: fix potentially dangerous trailing ';' in #defined values/expressions

2011-07-21T12:10:00+00:00

All these are instances of
  #define NAME value;
or
  #define NAME(params_opt) value;

These of course fail to build when used in contexts like
  if(foo $OP NAME)
  while(bar $OP NAME)
and may silently generate the wrong code in contexts such as
  foo = NAME + 1;    /* foo = value; + 1; */
  bar = NAME - 1;    /* bar = value; - 1; */
  baz = NAME & quux; /* baz = value; & quux; */

Reported on comp.lang.c,
Message-ID: 
Initial analysis of the dangers provided by Keith Thompson in that thread.

There are many more instances of more complicated macros having unnecessary
trailing semicolons, but this pile seems to be all of the cases of simple
values suffering from the problem. (Thus things that are likely to be found
in one of the contexts above, more complicated ones aren't.)

parisc: clear floating point exception flag on SIGFPE signal

2010-05-30T09:39:58+00:00

Clear the floating point exception flag before returning to
user space. This is needed, else the libc trampoline handler
may hit the same SIGFPE again while building up a trampoline
to a signal handler.

Fixes debian bug #559406.

kbuild: fix up CFLAGS usage

2007-10-14T19:49:42+00:00

Only in very rare cases is it needed to change CFLAGS
outside of arch/*/Makefile.
Fix up all wrong cases - in most cases
the use of EXTRA_CFLAGS is the only thing needed.
