Hi all,
This set of patches will add support for existing 32bit Android ashmem
syscalls on 64bit platforms. They also fix the ashmem pin/unpin interface
without affecting the 32bit ABI but imposing a new, correct one, for any
future 64bit Android userspace.
They have been successfully tested on 3
The values exchanged between kernel and userspace through struct
ashmem_pin should be of type size_t. This change won't affect the
existing interface but will stand as the basis of 64bit compat layer.

Android's shared memory subsystem, Ashmem, does not support calls from a
32bit userspace in a 64 bit kernel. This patch adds support for syscalls
coming from a 32bit userspace in a 64bit kernel.
The patch has been successfully tested on ARMv8 AEM(64bit
platform model) and Versatile Express A9(32bi

Can you accumulate all our discussion and create one right-coded,
kernelcode-styled patch?

Both pthreads and lockdep support dealing with rwlocks, so here's the
liblockdep implementation for those.

liblockdep is simply userspace lockdep. We can use that to analyze and
verify the locking in perf.
Usage is simple, to compile perf with liblockdep all that's needed it:
make LIBLOCK=[path to liblockdep]
Once liblockdep support is compiled in, perf will yell if locking goes
wrong for any
kernel/lockdep.c deals with validating locking scenarios for various
architectures supported by the kernel. There isn't anything kernel
specific going on in lockdep, and when we compare userspace to other
architectures that don't have to deal with irqs such as s390, they
become all too similar.

This is a rather simple and basic test suite to test common locking
issues.
Beyond tests, it also shows how to use the library.

These headers provide the same API as their pthread mutex counterparts.
The design here is to allow to easily switch to liblockdep lock validation
just by adding a "liblockdep_" to pthread_mutex_*() calls, which means that
it's easy to integrate liblockdep into existing codebases.

Thanks Pablo.
I have a question about commiting the patch for kernel.
Because i am the reporter of this issue, and I sent the similar fix to
netfilter maillist and the owner of the xt_hashlimit.c before.
Now it is that Greg commits the patch for this issue, not me, although
the fix is similar wit
