To make sure switcheroo() can execute when we remap all the executable
image, we used a trick to make it use a local copy of errno... this trick
does not work with NPTL glibc, only with LinuxThreads, so use another
(simpler) one to make it work anyway.Hopefully, a lot improved thanks to merging with the version of Al Viro
(which had his part of problems, though, i.e. removing a fix to another
bug and not fixing the problem on i386).Signed-off-by: Paolo 'Blaisorblade' Giarrusso

As suggested by Chris, we can make the "just added" method ->release
conditional to UML only (better: to archs requesting it, i.e. only UML
currently), so that other archs don't get this unneeded crud, and if UML
won't need it any more we can kill this.Signed-off-by: Paolo 'Blaisorblade' Giarrusso

This occurrence of free_irq_by_irq_and_dev() was missed when converting UML
to the use of hw_controller_type->release.Signed-off-by: Paolo 'Blaisorblade' Giarrusso

With Chris Wedgwood
Currently UML must explicitly call the UML-specific
free_irq_by_irq_and_dev() for each free_irq call it's done.This is needed because ->shutdown and/or ->disable are only called when the
last "action" for that irq is removed.Instead, for UML shared IRQs (UML IRQs are very often, if not always,
shared), for each dev_id some setup is done, which must be cleared on the
release of that fd. For instance, for each open console a new instance
(i.e. new dev_id) of the same IRQ is requested().Exactly, a fd is stored in an array (pollfds), which is after read by a
host thread and passed to poll(). Each event registered by poll() triggers
an interrupt. So, for each free_irq() we must remove the corresponding
host fd from the table, which we do via this -release() method.In this patch we add an appropriate hook for this, and remove all uses of
it by pointing the hook to the said procedure; this is safe to do since the
said procedure.Also some cosmetic improvements are included.
This is heavily based on some work by Chris Wedgwood, which however didn't
get the patch merged for something I'd call a "misunderstanding" (the need
for this patch wasn't cleanly explained, thus adding the generic hook was
felt as undesirable).Signed-off-by: Paolo 'Blaisorblade' Giarrusso

Several hardware features of SGI's IOC4 I/O controller chip require
timing-related driver calculations dependent upon the PCI bus speed. This
patch enables the core IOC4 driver code to detect the actual bus speed and
store a value that can later be used by the IOC4 subdrivers as needed.Signed-off-by: Brent Casavant

The SGI IOC4 I/O controller chip drivers are currently all configured by
CONFIG_BLK_DEV_SGIIOC4. This is undesirable as not all IOC4 hardware features
are needed by all systems.This patch adds two configuration variables, CONFIG_SGI_IOC4 for core IOC4
driver support (see patch 1/3 in this series for further explanation) and
CONFIG_SERIAL_SGI_IOC4 to independently enable serial port support.Signed-off-by: Brent Casavant

Signed-off-by: Linus Torvalds -
This series of patches reworks the configuration and internal structure
of the SGI IOC4 I/O controller device drivers.These changes are motivated by several factors:
- The IOC4 chip PCI resources are of mixed use between functions (i.e.
multiple functions are handled in the same address range, sometimes
within the same register), muddling resource ownership and initialization
issues. Centralizing this ownership in a core driver is desirable.- The IOC4 chip implements multiple functions (serial, IDE, others not
yet implemented in the mainline kernel) but is not a multifunction
PCI device. In order to properly handle device addition and removal
as well as module insertion and deletion, an intermediary IOC4-specific
driver layer is needed to handle these operations cleanly.- All IOC4 drivers are currently enabled by a single CONFIG value. As
not all systems need all IOC4 functions, it is desireable to enable
these drivers independently.- The current IOC4 core driver will trigger loading of all function-level
drivers, as it makes direct calls to them. This situation should be
reversed (i.e. function-level drivers cause loading of core driver)
in order to maintain a clear and least-surprise driver loading model.- IOC4 hardware design necessitates some driver-level dependency on
the PCI bus clock speed. Current code assumes a 66MHz bus, but the
speed should be autodetected and appropriate compensation taken.This patch series effects the above changes by a newly and better designed
IOC4 core driver with which the function-level drivers can register and
deregister themselves upon module insertion/removal. By tracking these
modules, device addition/removal is also handled properly. PCI resource
management and ownership issues are centralized in this core driver, and
IOC4-wide configuration actions such as bus speed detection are also
handled in this core driver.This patch:
The SGI IOC4 I/O controller chip implements multiple functions, though it is
not a multi-function PCI device. Additionally, various PCI resources of the
IOC4 are shared by multiple hardware functions, and thus resource ownership by
driver is not clearly delineated. Due to the current driver design, all core
and subordinate drivers must be loaded, or none, which is undesirable if not
all IOC4 hardware features are being used.This patch reorganizes the IOC4 drivers so that the core driver provides a
subdriver registration service. Through appropriate callbacks the subdrivers
can now handle device addition and removal, as well as module insertion and
deletion (though the IOC4 IDE driver requires further work before module
deletion will work). The core driver now takes care of allocating PCI
resources and data which must be shared between subdrivers, to clearly
delineate module ownership of these items.Signed-off-by: Brent Casavant

Currently we dynamically allocate the fake parent device for all devices on
the vio bus. This patch statically allocates it. This also allows us to
reuse it for the iSeries "generic" vio device (that is used for passing to
dma routines when communicating with the hypervisor without a device
involved). Also unexport vio_bus_type as it is never used in modules.Signed-off-by: Stephen Rothwell

The following kind of calls currently fails :
make ARCH=ppc64 CC="gcc-3.4"
Since the code for detecting a biarch compiler and adding the needed 64bit
magic argument fails if the AS/LD/CC commands are overriden in the command
line.The attached patch fixes this by using the make override and += directive,
but i am not 100% sure this will work without gmake, as i am no Makefile
