If the message type is W1_MASTER_CMD or W1_SLAVE_CMD, then a reference

Hi everyone,
This patch series adds support for read(), write(), and ioctl() operations
on eventpolls as well as an associated userspace structure to format the
eventpoll entries delivered via read()/write() buffers. The new structure,
struct epoll, differs from struct epoll_event mainly in that
Add a new 'struct epoll' to the userspace eventpoll interface. Buffers
supplied to read() write() calls on eventpolls are interpreted as
arrays of this structure. The new structure's only functional difference
from epoll_event is it also holds the associated file descriptor (needed
for write() to
Reserve a small ioctl() command space for eventpolls, of which only two
are currently utilized.

The eventpoll implementation is largely interface-agnostic, aside from the
userspace structure format and epoll_ctl(). Particularly as each field of the
structure is handled independently, replacing usage of epoll_event internally
was straighforward and clarifies the code some. As for epoll_ctl(),

Arm64 supports 32-bit mode(AArch32) and 64-bit mode(AArch64).
To enable audit on arm64, we want to use lib/audit.c and re-work it
to support compat system calls as well without copying it under

Since this patch is implemented in much the same way as on existing
lib/audit.c provides a generic definition for auditing system calls.
This patch extends it for compat syscall support on bi-architectures
(32/64-bit) by adding lib/compat_audit.c.
What is required to support this feature are:
* add asm/unistd32.h for compat system call names
* enable
This patchset adds system call audit support on arm64.
Both 32-bit (AUDIT_ARCH_ARM) and 64-bit tasks (AUDIT_ARCH_AARCH64)
are supported. Since arm64 has the exact same set of system calls
on LE and BE, we don't care about endianness (or more specifically
__AUDIT_ARCH_64BIT bit in AUDIT_ARCH_*).
This macro, regs_return_value, is used mainly for audit to record system
call's results, but may also be used in test_kprobes.c.
