sparc64: Fix deficiencies in sun4v error reporting.

2012-10-11T00:19:32Z

Missing error types, attributes, and report fields. Pad out to 64-bytes. Make string reporting cleaner and easier to extend in the future using "const char *" arrays that index by either bit position, or absolute field value. Report the raw 64-byte error report as a sequence of u64s before the annotated version. Only report fields which are valid, given the context and the attribute bits which are set. For shutdown requests, use the local copy of the error report not the one we just freed up back to the queue. Also, use orderly_poweroff() just like the Domain Services shutdown request code does. If the real-address reported is "-1" (unknown) try to disassemble the instruction to report the effective address of the access. Only do this in privileged mode. Signed-off-by: David S. Miller

sparc: fix format string argument for prom_printf()

2012-10-03T03:20:34Z

prom_printf() takes printf style arguments. Specifing GCC's format attribute reveals that there are several wrong usages of prom_printf(). This fixes those wrong format strings and arguments, and also leaves format attributes in order to detect similar mistakes at compile time. Signed-off-by: Akinobu Mita Cc: "David S.

sparc64: Fix several bugs in quad floating point emulation.

2012-05-25T07:31:56Z

UltraSPARC-T2 and later do not use the fp_exception_other trap and do not set the floating point trap type field in the %fsr at all when you try to execute an unimplemented FPU operation. Instead, it uses the illegal_instruction trap and it leaves the floating point trap type field clear. So we should not validate the %fsr trap type field when do_mathemu() is invoked from the illegal instruction handler. Also, the floating point trap type field is 3 bits, not 4 bits.

sparc: Remove unnecessary semicolons

2011-06-07T23:06:34Z

Semicolons are not necessary after switch/while/for/if braces so remove them. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

sparc64: Fix build errors with gcc-4.6.0

2011-03-17T01:19:15Z

Most of the warnings emitted (we fail arch/sparc file builds with -Werror) were legitimate but harmless, however one case (n2_pcr_write) was a genuine bug. Based almost entirely upon a patch by Sam Ravnborg. Reported-by: Dennis Gilmore Signed-off-by: David S. Miller

sparc64: Fix stack dumping and tracing when function graph is enabled.

2010-04-21T10:08:11Z

Like x86, when the function graph tracer is enabled, emit the ftrace stub as well as the program counter it will be transformed back into. We duplicate a lot of similar stack walking logic in 3 or 4 spots, so eventually we should consolidate things like x86 does. Thanks to Frederic Weisbecker for pointing this out.

sparc64: Use kstack_valid() in die_if_kernel().

2010-04-13T05:16:22Z

This gets rid of a local function (is_kernel_stack()) which tries to do the same thing, yet poorly in that it doesn't handle IRQ stacks properly. Signed-off-by: David S. Miller
