2cfa7660db [MIPS] time: Delete dead cycles_per_jiffy, mips_timer_ack and null_timer_ack
cycles_per_jiffy was only ever getting assigned and the function pointer
not being called anymore and mips_timer_ack had gotten similarly stale.  I
leave the remaining assignments unfixed as a lighthouse pointing platform
maintainers to what needs a rewrite.  These changes make null_timer_ack()
unreferenced, so delete that too.

15ad838d28 [MIPS] Always do the ARC64_TWIDDLE_PC thing.
Always jump to the place where the kernel is linked to. This helps where
the bootloaders/proms ignores the start address inside the ELF header.

88e4d25023 x86: delete vsyscall files during make clean
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.

982c37cfb6 9p: remove sysctl
A sysctl method was added to enable and disable debugging levels.  After

and the sysctl methodology isn't really desirable.  This patch removes the

50fd801067 9p: soften invalidation in loose_mode

ba17674fe0 9p: attach-per-user
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.
