	---help---
	  Say Y here if you want to build support for the IrDA (TM) protocols.
	  The Infrared Data Associations (tm) specifies standards for wireless
	  infrared communication and is supported by most laptops and PDA's.

	  To use Linux support for the IrDA (tm) protocols, you will also need
	  some user-space utilities like irattach.  For more information, see
	  the file <file:Documentation/networking/irda.txt>.  You also want to
	  read the IR-HOWTO, available at
	  <http://www.tldp.org/docs.html#howto>.

	  If you want to exchange bits of data (vCal, vCard) with a PDA, you
	  will need to install some OBEX application, such as OpenObex :
	  <http://sourceforge.net/projects/openobex/>

	  To compile this support as a module, choose M here: the module will
	  be called irda.

config IRDA_ULTRA
	bool "Ultra (connectionless) protocol"
	depends on IRDA
	help
	  Say Y here to support the connectionless Ultra IRDA protocol.
	  Ultra allows to exchange data over IrDA with really simple devices
	  (watch, beacon) without the overhead of the IrDA protocol (no handshaking,
	  no management frames, simple fixed header).
	  Ultra is available as a special socket : socket(AF_IRDA, SOCK_DGRAM, 1);

config IRDA_CACHE_LAST_LSAP
	bool "Cache last LSAP"
	depends on IRDA
	help
	  Say Y here if you want IrLMP to cache the last LSAP used.  This
	  makes sense since most frames will be sent/received on the same
	  connection.  Enabling this option will save a hash-lookup per frame.

	  If unsure, say Y.

config IRDA_FAST_RR
	bool "Fast RRs (low latency)"
	depends on IRDA
	---help---
	  Say Y here is you want IrLAP to send fast RR (Receive Ready) frames
	  when acting as a primary station.
	  Disabling this option will make latency over IrDA very bad. Enabling
	  this option will make the IrDA stack send more packet than strictly
	  necessary, thus reduce your battery life (but not that much).

	  Fast RR will make IrLAP send out a RR frame immediately when
	  receiving a frame if its own transmit queue is currently empty. This
	  will give a lot of speed improvement when receiving much data since
	  the secondary station will not have to wait the max. turn around
	  time (usually 500ms) before it is allowed to transmit the next time.
	  If the transmit queue of the secondary is also empty, the primary will
	  start backing-off before sending another RR frame, waiting longer
	  each time until the back-off reaches the max. turn around time.
	  This back-off increase in controlled via
	  /proc/sys/net/irda/fast_poll_increase

	  If unsure, say Y.

config IRDA_DEBUG
	bool "Debug information"
	depends on IRDA
	help
	  Say Y here if you want the IrDA subsystem to write debug information
	  to your syslog. You can change the debug level in
	  /proc/sys/net/irda/debug .
	  When this option is enabled, the IrDA also perform many extra internal
	  verifications which will usually prevent the kernel to crash in case of
	  bugs.

	  If unsure, say Y (since it makes it easier to find the bugs).

====================
sparc64: Recover from userspace non-resumable PIO &amp; MEM errors

A non-resumable error from userspace is able to cause a kernel panic or trap
loop due to the setup and handling of the queued traps once in the kernel.
This patch series addresses both of these issues.

The queues are fixed by simply zeroing the memory before use.

PIO errors from userspace will result in a SIGBUS being sent to the user
process.

The MEM errors form userspace will result in a SIGKILL and also cause the
offending pages to be claimed so they are no longer used in future tasks.
SIGKILL is used to ensure that the process does not try to coredump and result
in an attempt to read the memory again from within kernel space.  Although
there is a HV call to scrub the memory (mem_scrub), there is no easy way to
guarantee that the real memory address(es) are not used by other tasks.
Clearing the error with mem_scrub would zero the memory and cause the other
processes to proceed with bad data.

The handling of other non-resumable errors remain unchanged and will cause a
panic.
