..and only enable them for ia64. The functions are only valid when the whole system has been totally stopped and no scheduler activity is ongoing on any CPU, and interrupts are globally disabled. In other words, they aren't useful for anything else. So make sure that nobody can use them by mistake. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Update i810fb documentation to describe new features and configuration changes. Signed-off-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Reported by: Manuel Lauss <mano@roarinelk.homelinux.net> He was getting random initial video modes depending on the kernel configuration. His option line includes 'extvga'. The i810fb documentation describes the option 'extvga', however the driver accepts 'ext_vga'. Besides 'extvga' being ignored by i810fb, it also confuses the option parser of i810fb and assigns 'extvga' to 'mode_option'. This leads to an incorrect video mode at boot time.

Move call to get_mm_counter() in update_mem_hiwater() to be inside the check for tsk->mm being null. Otherwise you can be following a null pointer here. This patch submitted by Javier Herrero <jherrero@hvsistemas.es>. Modify the end check for munmap regions to allow for the legacy behavior of 0 being valid. Pretty much all current uClinux system libc malloc's pass in 0 as the end point. A hard check will fail on these, so change the check so that if it is non-zero it must be valid otherwise it fails. A passed in value will always succeed (as it used too). Also export a few more mm system functions - to be consistent with the VM code exports.

A few improvements to the Freescale/ColdFire FEC driver: . some formatting cleanups . add support for the FEC device in the ColdFire 523x processor family . add support for MAC address setting on MOD5272 and M5272C3 boards . don't re-read the PHY status register many times . ack status interrupt before reading status register . move printing init message to after full init (so that the ethX name is filled out for printing) Some parts of this patch submitted by Philippe De Muyter <phdm@macqel.be> Signed-off-by: Greg Ungerer <gerg@uclinux.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

The bulk of the change. Use per cpu MCA/INIT stacks. Change the SAL to OS state (sos) to be per process. Do all the assembler work on the MCA/INIT stacks, leaving the original stack alone. Pass per cpu state data to the C handlers for MCA and INIT, which also means changing the mca_drv interfaces slightly. Lots of verification on whether the original stack is usable before converting it to a sleeping process. Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

Reading the INIT record from SAL during the INIT event has proved to be unreliable, and a source of hangs during INIT processing. The new MCA/INIT handlers remove the need to get the INIT record from SAL. Change salinfo.c so mca.c can just flag that a new record is available, without having to read the record during INIT processing. This patch can be applied without the new MCA/INIT handlers. Also clean up some usage of NR_CPUS which should have been using cpu_online(). Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

When introducing the generic asm-offsets.h support the dependency chain for the prepare targets was changed. All build scripts expecting include/asm/asm-offsets.h to be made when using the prepare target would broke. With the limited number of prepare targets left in arch Makefiles the trivial solution was to introduce a new arch specific target: archprepare The dependency chain looks like this now: prepare | +--> prepare0 | +--> archprepare | +--> scripts_basic +--> prepare1 | +---> prepare2 | +--> prepare3 So prepare 3 is processed before prepare2 etc. This guaantees that the asm symlink, version.h, scripts_basic are all updated before archprepare is processed. prepare0 which build the asm-offsets.h file will need the actions performed by archprepare. The head target is now named prepare, because users scripts will most likely use that target, but prepare-all has been kept for compatibility. Updated Documentation/kbuild/makefiles.txt.

This ports the Sun GEM ROM mapping/enable fixes it sunhme (which used the same PCI ROM mapping code). Without this, I get NULL MAC addresses for all 4 ports (it's a SUN QFE).

This same patch was reported to fix the MAC address detection on sunhme (next patch). Most people seem to be running this on Sparcs or PPC machines, where we get the MAC address from their respective firmware rather than from the (previously broken) ROM mapping routines.
