(XXX sa_yieldcall() and sa_switchcall() should be combined and take
arg as the function to call, but I'm somewhat nervous about void *
vs. void (*)()).
we read-lock the map and call uvm_map_lookup_entry() instead of simply
walking from the header to the next and to the next, etc.
Dumping from sparsely populated amaps could cause faults that would
result in amaps being split, which (in turn) resulted in the core
dumping routines dumping some regions of memory twice. This makes the
core file too large, the headers not match, gdb not work properly,
and so on.
Addresses PR 19260.
acpi_is_global_locked() functions.
AcpiGlobalLock() API should be used to acquire lock between BIOS and OS.
This API cannot be used to lock between threads of the OS side,
because this function immediately returns if the lock is already acquired
by the OS. c.f. AcpiEvAcquireGlobalLock()@evmisc.c
- make sure that acpiec driver uses above functions.
- use ACPI_ALLOCATE_BUFFER instead of twice calls of AcpiEvaluateObject(),
in acpi_eval_string()/acpi_eval_struct().
Twice AcpiEvaluateObject() calls may cause twice side effects
to ACPI machine / hardware and this may be wrong in some cases.
This makes simple lock work on big-endian platforms.
- Assembly-level optimization of __cpu_simple_lock_try().
OK'd by Gregory McGarry. Closes PR port-sh3/20311.
-e arg to abort after first error.
This means the extract process doesn't spew seemingly-endless
"No space left on device" if the destination partition fills.
Accidentally left eval = 1 when I was adding the extension which caused the rm command to return a 1 when it successfully removed a directory. Thanks to tron for catching it.
in mii_readreg()/mii_writereg(). Also restore this bit based on the
currently selected media instance every time we need to reinitialise
the interface.
- Don't invoke kevent(2) for every single event change. Instead collect
event changes and try to do them in the event loop.
- Handle signals via kevent(2) to avoid race conditions for SIGHUP (which
probably exist in the select(2) based implementation, too).
