They were either used to report that changing voltage is not allowed, or that
changing voltage failed.Signed-off-by: Dominik Brodowski
-
CS_UNSUPPORTED_MODE and CS_UNSUPPORTED_FUNCTION were mostly used to denote
trying to use PCMCIA functions on CardBus cards.Signed-off-by: Dominik Brodowski
-
CS_OUT_OF_RESOURCE was almost only used to note -ENOMEM situations.
Therefore, use -ENOMEM explicitely, and also print out warnings.CC: netdev@vger.kernel.org

Deprecate unused CS_ error codes by replacing their definitions with
generic error messages, and removing them from the error_t lookup table.Signed-off-by: Dominik Brodowski
-
Instead of using own error or success codes, the PCMCIA code should rely on
the generic return values. Therefore, replace all occurrences of CS_SUCCESS
with 0.CC: netdev@vger.kernel.org

With the PCMCIA ioctl being the only remaining user of
_get_configuration_info, move the function to pcmcia_ioctl.cSigned-off-by: Dominik Brodowski
-
Remove the three remaining pcmcia_get_configuration_info() users:
- pcmciamtd is marked broken anyway.
- serial_cs.c can access the relevant structs directly
- ipwireless didn't use the outputCC: linux-serial@vger.kernel.org

By passing the current Vcc setting to the pcmcia_config_loop callback
function, we can remove pcmcia_get_configuration_info() calls from many
drivers.Signed-off-by: Dominik Brodowski

Many drivers use the default CIS entry within their pcmcia_config_loop()
callback function. Therefore, factor the default CIS entry handling out.Signed-off-by: Dominik Brodowski
-
Almost all drivers set p_dev->conf.ConfigIndex to cfg->index in
the pcmcia_config_loop() callback function. Therefore, factor it out.Signed-off-by: Dominik Brodowski

Use the config loop helper in misc pcmcia drivers.

By calling pcmcia_loop_config(), a pcmcia driver can iterate over all
available configuration options. During a driver's probe() phase, one
doesn't need to use pcmcia_get_{first,next}_tuple, pcmcia_get_tuple_data
and pcmcia_parse_tuple directly in most if not all cases.Signed-off-by: Dominik Brodowski

Instead of copying CIS override data in socket_sysfs.c or ds.c, and then again
in cistpl.c, only do so once. Also, cisdump_t is now only used by the

[SCSI] qla2xxx: fix msleep compile error -
Alexey Dobriyan reported trouble with LTP with the new fast-gup code,
and Johannes Weiner debugged it to non-page-aligned addresses, where the
new get_user_pages_fast() code would do all the wrong things, including
just traversing past the end of the requested area due to 'addr' never
matching 'end' exactly.This is not a pretty fix, and we may actually want to move the alignment
into generic code, leaving just the core code per-arch, but Alexey
verified that the vmsplice01 LTP test doesn't crash with this.Reported-and-tested-by: Alexey Dobriyan

lguest uses a Waker process to break it out of the kernel (ie.
actually running the guest) when file descriptor needs attention.Changing this from a process to a thread somewhat simplifies things:
it can directly access the fd_set of things to watch. More
importantly, it means that the Waker can see Guest memory correctly,
so /dev/vring file descriptors will work as anticipated (the
alternative is to actually mmap MAP_SHARED, but you can't do that with
/dev/zero).Signed-off-by: Rusty Russell

Since the correct timeout value varies, use a heuristic which adjusts
the timeout depending on how many packets we've seen. This gives
slightly worse results, but doesn't need tweaking when GSO is
introduced.500 usec 19.1887 xmit 561141 recv 1 timeout 559657

virtio_ring has the ability to suppress notifications. This prevents
a guest exit for every packet, but we need to set a timer on packet
receipt to re-check if there were any remaining packets.Here are the times for 1G TCP Guest->Host with different timeout
settings (it matters because the TCP window doesn't grow big enough to
fill the entire buffer):Timeout value Seconds Xmit/Recv/Timeout
