Failing to create the links doesn't seem like a fatal error in these

If we have a SuckyIO, and pci_enable_device fails, we'll be in a world of

Sam's previous patch missed a few uses of ASM_PAGE_SIZE.

We have the macro _AC() generally available now
so the calculation of PAGE_SIZE can be made
assembler compatible.
Introduce use of _AC() and kill all users of
ASM_PAGE_SIZE.

Introduce a consistent layout of vmlinux.
The same layout has been introduced for most
architectures.
And the same time move a few label definitions inside
the curly brackets so they are assigned the correct
starting address. Before a ld inserted alignment
would have casued the label to pint before the actual
start of the section.

Currently we're hacking libs-y to include libgcc.a, but this has
unforeseen consequences since the userspace libgcc is linked with fpregs
enabled. We need the kernel to stop using fpregs in an uncontrolled manner
to implement lazy fpu state saves.

Slab pages obtained via kmalloc are not cacheline aligned. Nor is it
advisable to perform VM operations designed for page allocator pages on
memory obtained via kmalloc.
So replace the page sized allocations in kernel/pci-dma.c with page allocator
pages.

make clean failed to delete a few files in
x86/kernel. This is because kbuild does not
see the correct/full kernel/Makefile.
As a workaround until the Makefiles are merged specify
the files to be deleted in the common Makefile.

Loose mode in 9p utilizes the page cache without respecting coherency with
the server. Any writes previously invaldiated the entire mapping for a file.

write.

The 9P2000 protocol requires the authentication and permission checks to be
done in the file server. For that reason every user that accesses the file
server tree has to authenticate and attach to the server separately.
Multiple users can share the same connection to the server.
Currently v9fs does a single attach and executes all I/O operations as a
single user. This makes using v9fs in multiuser environment unsafe as it
depends on the client doing the permission checking.
This patch improves the 9P2000 support by allowing every user to attach
separately. The patch defines three modes of access (new mount option
'access'):
- attach-per-user (access=user) (default mode for 9P2000.u)
If a user tries to access a file served by v9fs for the first time, v9fs
sends an attach command to the server (Tattach) specifying the user. If
the attach succeeds, the user can access the v9fs tree.
As there is no uname->uid (string->integer) mapping yet, this mode works
only with the 9P2000.u dialect.
- allow only one user to access the tree (access=<uid>)
Only the user with uid can access the v9fs tree. Other users that attempt
to access it will get EPERM error.
- do all operations as a single user (access=any) (default for 9P2000)
V9fs does a single attach and all operations are done as a single user.
If this mode is selected, the v9fs behavior is identical with the current
one.
