headers: remove sched.h from interrupt.h

2009-10-11T18:20:58+00:00

After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!
Many thanks to Heiko Carstens for allowing this.

lguest: cleanup for map_switcher()

2009-09-23T12:56:47+00:00

We can use alloc_page() instead of get_zeroed_page() and virt_to_page()

lguest: use PGDIR_SHIFT for PAE code to allow different PAGE_OFFSET

2009-09-23T12:56:46+00:00

We still assume the Guest and Host have the same PAGE_OFFSET settings,
but now we don't assume 0xC0000000.

lguest: use set_pte/set_pmd uniformly for real page table entries

2009-09-23T12:56:46+00:00

If we're building a pte, we can use simple assigment; only use set_pte
etc. when we're actually going to use that destination as a PTE.  I
don't know that we'll ever run under Xen, but it's neater.

And use set_pte/set_pmd rather than assuming native_ versions, even
though that's probably true for most people.

lguest and virtio: cleanup struct definitions to Linux style.

2009-07-30T06:33:46+00:00

I've been doing this for years, and akpm picked me up on it about 12
months ago.  lguest partly serves as example code, so let's do it Right.

Also, remove two unused fields in struct vblk_info in the example launcher.

2009-07-30T06:33:46+00:00

Every so often, after code shuffles, I need to go through and unbitrot
the Lguest Journey (see drivers/lguest/README).  Since we now use RCU in
a simple form in one place I took the opportunity to expand that explanation.

lguest: fix comment style

2009-07-30T06:33:45+00:00

I don't really notice it (except to begrudge the extra vertical
space), but Ingo does.  And he pointed out that one excuse of lguest
is as a teaching tool, it should set a good example.
