be updated. (This is needed to be compatible with how pre-SIGINFO signals
operated. If you siglongjmp out of a signal handler, the SS_ONSTACK state
needs to be cleared. This commit restores that functionality).
- RAS_DECL(name): declare the RAS "name"
- RAS_START(name): mark the start of the RAS "name"
- RAS_END(name): mark the end of the RAS "name"
- RAS_ADDR(name): compute the starting address of the RAS "name"
- RAS_SIZE(name): compute the size of the RAS "name"
RAS_START() and RAS_END() have implicit instruction reordering barriers.
RAS_ADDR() and RAS_SIZE() are to be used when registering a RAS.
-if a new process gets a CPU with an FPU state of another process, it
needs to initialize it to a clean state
(actually, put the "fninit" where it belongs logically)
-initialize mxcsr as well
minor cleanup/optimization
Signal delivery after unmasking some cause is still broken - it doesn't
care about xmm exceptions. For now, set at least si_code to something
positive so that it doesn't look like a user generated asynchonous signal.
This removes 3 more RF_PANIC()'s (but we'll currently still panic if any of these cases occur).
fix up a few printf's.
XXX: still needs more cleanup and testing (and be taught to not panic).
- remove callbackArg2 from RF_CallbackDesc_s -- it is only ever set,
never read.
- now that this is done, all callbacks should only take a single argument,
and we can simplify things further.

Patch from Juergen Hannken-Illjes via lukem@
should resolve pr#24620
+ add -DFONTMODULE -DMODNAME=${LIB} for xtt modules
+ add required include paths for FONTMODULE, MODNAME
Fix as per changes in pr by Kouichirou Hiratsuka
This should resolve pr#24032
- change function signature of rf_LookupRUStatus(). The last argument
is now a pointer to a new PSS, in case one is needed. Rather than
having rf_LookupRUStatus() allocate a new PSS, we pre-allocate one
beforehand, where necessary, just in case.
- change callers of rf_lookupRUStatus() to deal with the new way of
calling rf_lookupRUStatus().
[no improvement or worsening of parity rebuild/initialization performance.]
[For the record: The mcpair mutex is being used to protect mcpair->flag.
mcpair gets allocated before each call to rf_DispatchDAG(), so there is no
other process/thread that could be mucking with it. It is only used to
detect the completion of a given parity unit, and rf_DispatchDAG()
only uses it to setup the callback argument for rf_MCPairWakeupFunc()
which will be called when the IO completes. The code after the call
to rf_DispatchDAG() sits and waits for a 'wakeup' on mcpair->cond
(rf_MCPairWakeupFunc() does that). If mcpair->flag is 0 when
rf_DispatchDAG() completes, then rf_MCPairWakeupFunc() hasn't been
called yet (the IO hasn't completed). If it is 1, then the IO is
already done, and we continue on our merry way without sleeping.
Thus, we don't need to hold any lock on mcpair while calling
rf_DispatchDAG().]
