Allocate/release a chunk of vmalloc address space:
alloc_vm_area reserves a chunk of address space, and makes sure all
the pagetables are constructed for that address range - but no pages.free_vm_area releases the address space range.

__supported_pte_mask is needed when constructing pte values. Xen
device drivers need to do this to make mappings of foreign pages (ie,
pages granted to us by other domains).Signed-off-by: Jeremy Fitzhardinge

When running with CONFIG_PARAVIRT, we may want lots of IRQs even if
there's no IO APIC.Signed-off-by: Jeremy Fitzhardinge
Cc: "Eric W. Biederman" -
Add a hook so that the paravirt backend knows when the allocator is
ready. This is useful for the obvious reason that the allocator is
available, but the other side-effect of having the bootmem allocator
available is that each page now has an associated "struct page".Signed-off-by: Jeremy Fitzhardinge

It's useful to know which mm is allocating a pagetable. Xen uses this
to determine whether the pagetable being added to is pinned or not.Signed-off-by: Jeremy Fitzhardinge

Use existing elfnote.h to generate vsyscall notes, rather than doing
it locally. Changes elfnote.h a bit to suit, since this is the first
asm user, and it wasn't quite right.Signed-off-by: Jeremy Fitzhardinge

Rather than using a tri-state integer for the wait flag in
call_usermodehelper_exec, define a proper enum, and use that. I've
preserved the integer values so that any callers I've missed should
still work OK.Signed-off-by: Jeremy Fitzhardinge

Various pieces of code around the kernel want to be able to trigger an
orderly poweroff. This pulls them together into a single
implementation.By default the poweroff command is /sbin/poweroff, but it can be set
via sysctl: kernel/poweroff_cmd. This is split at whitespace, so it
can include command-line arguments.This patch replaces four other instances of invoking either "poweroff"
or "shutdown -h now": two sbus drivers, and acpi thermal
management.sparc64 has its own "powerd"; still need to determine whether it should
be replaced by orderly_poweroff().Signed-off-by: Jeremy Fitzhardinge

Rather than having hundreds of variations of call_usermodehelper for
various pieces of usermode state which could be set up, split the
info allocation and initialization from the actual process execution.This means the general pattern becomes:
info = call_usermodehelper_setup(path, argv, envp); /* basic state */
call_usermodehelper_(info, stuff...); /* extra state */
call_usermodehelper_exec(info, wait); /* run process and free info */This patch introduces wrappers for all the existing calling styles for
call_usermodehelper_*, but folds their implementations into one.Signed-off-by: Jeremy Fitzhardinge

argv_split() is a helper function which takes a string, splits it at
whitespace, and returns a NULL-terminated argv vector. This is
deliberately simple - it does no quote processing of any kind.[ Seems to me that this is something which is already being done in
the kernel, but I couldn't find any other implementations, either to
steal or replace. Keep an eye out. ]Signed-off-by: Jeremy Fitzhardinge

Add a kstrndup function, modelled on strndup. Like strndup this
returns a string copied into its own allocated memory, but it copies
no more than the specified number of bytes from the source.Remove private strndup() from irda code.

This is a reimplementation of the zs driver for the serial subsystem. Any
resemblance to the old driver is purely coincidential. ;-) I do hope I got
the handling of modem lines right -- better do not tackle me about the
issue unless you feel too good...Any users of the old driver: please note the numbers of the serial lines
have now been swapped, i.e. ttyS0 ttyS1 and ttyS2 ttyS3. It has
to do with the modem lines mentioned above; basically the port A in a given
chip has to be initialised before the port B if you want to use the latter
as the serial console (which is usually the case), as operations on modem
lines of the serial line associated with the port B access both ports (see
the comment at the top of the driver for the details of wiring used).
Please update your scripts.This is also the reason each SCC now requests an IRQ once only (as seen in
"/proc/interrupts") -- the handler takes care of both ports at once as the
line associated with the port B has to take status update interrupts from
both ports (and yet the line of the port A takes its own for itself too).
The old driver never got it right...Signed-off-by: Maciej W. Rozycki

The old IDE driver is not ready to take generic SCSI commands, even if
it uses them for some specific issues (ie the tray open/close ioctls for
IDE CD-ROM's). Pointed out by Bartlomiej.I'm sure we'll have it fixed properly soon enough, but for now we should
not allow it to cause problems.Cc: Bartlomiej Zolnierkiewicz

1) Remove CONFIG_PCI ifdefs. PCI is required in Kconfig.
2) Break up setup_netjet_s() into three separate internal functions.
This helps facilitate upcoming use of PCI hotplug API, and in addition
makes the code much easier to follow.No code is changed, just moved around. I even kept the out-of-favor
"return(0)" style used in the current source code.Signed-off-by: Jeff Garzik
