[PATCH] Add 32-bit compatibility for NFSv4 mount
This adds 32-bit compatibility for mounting an NFSv4 mount on a 64-bit
kernel (such as happens with PPC64).
The problem is that the mount data for the NFS4 mount process includes
auxilliary data pointers, probably because the NFS4 mount data may
conceivably exceed PAGE_SIZE in size - thus breaking against the hard
limit imposed by sys_mount().

[PATCH] SELinux: fix deadlock on dcache lock
This fixes a deadlock on the dcache lock detected during testing at IBM
by moving the logging of the current executable information from the
SELinux avc_audit function to audit_log_exit (via an audit_log_task_info
helper) for processing upon syscall exit.
For consistency, the patch also removes the logging of other
task-related information from avc_audit, deferring handling to
audit_log_exit instead.
This allows simplification of the avc_audit code, allows the exe
information to be obtained more reliably, always includes the comm
information (useful for scripts), and avoids including bogus task
information for checks performed from irq or softirq.

[PATCH] sparc64: Reduce ptrace cache flushing
We were flushing the D-cache excessively for ptrace() processing
and this makes debugging threads so slow as to be totally unusable.
All process page accesses via ptrace() go via access_process_vm().
This routine, for each process page, uses get_user_pages(). That
in turn does a flush_dcache_page() on the child pages before we
copy in/out the ptrace request data.
Therefore, all we need to do after the data movement is:
1) Flush the D-cache pages if the kernel maps the page to a different
color than userspace does.
2) If we wrote to the page, we need to flush the I-cache on older cpus.
Previously we just flushed the entire cache at the end of a ptrace()
request, and that was beyond stupid.

[PATCH] sparc: Fix PTRACE_CONT bogosity
SunOS aparently had this weird PTRACE_CONT semantic which
we copied. If the addr argument is something other than
1, it sets the process program counter to whatever that
value is.
This is different from every other Linux architecture, which
don't do anything with the addr and data args.
This difference in particular breaks the Linux native GDB support
for fork and vfork tracing on sparc and sparc64.
There is no interest in running SunOS binaries using this weird
PTRACE_CONT behavior, so just delete it so we behave like other
platforms do.

This case actually can get exercised a lot during an ELF
coredump of a process which contains a lot of non-COW'd

creates near terabyte process full of ZERO_PAGEes. It takes

all of these spurious cache flushes on sparc64.

This reverts a fs/char_dev.c patch that was merged into BK on March 3.
The problem is that it breaks things ... __register_chrdev_region() has
a block of code, commented "temporary" for over two years now, which
fails rudely during PCMCIA initialization or other register_chrdev()
calls, because it doesn't "degrade to linked list". This keeps whole
subsystems from working.
A real fix to that "temporary" code should be possible, using some better
scheme to allocate major numbers, but it's not something I want to spend
time on just now.
