xfs_read_buf() where some function calls later it gets dereferenced by an

Allow lseek(mtdchar_fd, 0, SEEK_END) to succeed, which currently fails
with EINVAL.
lseek(fd, 0, SEEK_END) should result into the same fileposition as
lseek(fd, 0, SEEK_SET) + read(fd, buf, length(fd))
Furthermore, lseek(fd, 0, SEEK_CUR) should return the current file position,
which in case of an encountered EOF should not result in EINVAL

Builds on ARM report link problems with common configurations like
statically linked NFS (for nfsroot). The symptom is that __init
section code references __exit section code; that won't work since
the exit sections are discarded (since they can never be called).
The best fix for these particular cases would be an "__init_or_exit"
section annotation.

Currently /proc/iomem exports physical memory also apart from io device
memory. But on i386, it truncates any memory more than 4GB. This leads to
problems for kexec/kdump.
Kexec reads /proc/iomem to determine the system memory layout and prepares a
memory map based on that and passes it to the kernel being kexeced. Given the
fact that memory more than 4GB has been truncated, new kernel never gets to
see and use that memory.
Kdump also reads /proc/iomem to determine the physical memory layout of the
system and encodes this informaiton in ELF headers. After a crash new kernel
parses these ELF headers being used by previous kernel and vmcore is prepared
accordingly. As memory more than 4GB has been truncated, kdump never sees
that memory and never prepares ELF headers for it. Hence vmcore is truncated
and limited to 4GB even if there is more physical memory in the system.
This patch exports memory more than 4GB through /proc/iomem on i386.

In jffs2_release_xattr_datum(), it refers xd->refcnt to ensure
whether releasing xd is allowed or not.
But we can't hold xattr_sem since this function is called under
spin_lock(&c->erase_completion_lock). Thus we have to refer it
without any locking.

- When xref is removed, a new xref with 'delete marker' is written.

- delete_xattr_(datum/xref)_delay() are new deletion functions
