Android uses the ashmem driver [1] for creating shared memory regions
between processes. The ashmem driver exposes an ioctl command for
processes to restrict the permissions an ashmem buffer can be mapped
with.

Hi,
In /proc/PID/stat, there is the kstkesp field which is the stack pointer of
a thread. While the thread is active, this field reads zero. But during a
coredump, it should have a valid value.
However, at the moment, kstkesp is zero even during coredump.
The first commit fixes this problem, and
The field "eip" (instruction pointer) and "esp" (stack pointer) of a task
can be read from /proc/PID/stat. These fields can be interesting for
coredump.
However, these fields were disabled by commit 0a1eb2d474ed ("fs/proc: Stop
reporting eip and esp in /proc/PID/stat"), because it is generally uns
Add a test which checks that the kstkesp field in /proc/pid/stat can be

For full details including the motivation for this test and how it works,

Android currently uses the ashmem driver [1] for creating shared memory
regions between processes. Ashmem buffers can initially be mapped with
PROT_READ, PROT_WRITE, and PROT_EXEC. Processes can then use the
ASHMEM_SET_PROT_MASK ioctl command to restrict--never add--the
permissions that the buffer

When working on OpenRISC support for restartable sequences I noticed
and fixed these two issues with the riscv support bits.
1 The 'inc' argument to RSEQ_ASM_OP_R_DEREF_ADDV was being implicitly
passed to the macro. Fix this by adding 'inc' to the list of macro
arguments.
