In the case when the phy_mask is bitwise anded with the phy_index bit is
zero the continue statement currently jumps to the next iteration of the
while loop and phy_index is never actually incremented, potentially
causing an infinite loop if phy_index is less than SCI_MAX_PHS. Fix this
by turning the while loop into a for loop.

The read_persistent_clock() uses a timespec, which is not year 2038 safe
on 32bit systems. On parisc architecture, we have implemented generic
RTC drivers that can be used to compensate the system suspend time, but
the RTC time can not represent the nanosecond resolution, so this patch
just converts to read_persistent_clock64() with timespec64.

so that put_pages() would properly clean up pages in the failure

However, this means that put_pages() now needs to check that
msm_gem_object::sgt is not null before trying to clean it up, and
this check was only applied to part of the cleanup code. Move
it all into the conditional block. (Strictly speaking we don't
need to make the kfree() conditional, but since we can't avoid
checking for null ourselves we may as well do so.)

Instead of always multicasting responses, send a unicast netlink message
directed at the correct pid. This will be needed if we ever want to
support multiple userspace processes interacting with the kernel over
iSCSI netlink simultaneously. Limitations can currently be seen if you
attempt to run multiple iscsistart commands in parallel.
We've fixed up the userspace issues in iscsistart that prevented
multiple instances from running, so now attempts to speed up booting by
bringing up multiple iscsi sessions at once in the initramfs are just
running into misrouted responses that this fixes.

When configuring the number of used bearers to MAX_BEARER and issuing
command "tipc link monitor summary", the command enters infinite loop
in user space.
This issue happens because function tipc_nl_node_dump_monitor() returns
the wrong 'prev_bearer' value when all potential monitors have been
scanned.
The correct behavior is to always try to scan all monitors until either
the netlink message is full, in which case we return the bearer identity
of the affected monitor, or we continue through the whole bearer array
until we can return MAX_BEARERS. This solution also caters for the case
where there may be gaps in the bearer array.

Both ecryptfs_filldir() and ecryptfs_readlink_lower() use
ecryptfs_decode_and_decrypt_filename() to translate lower filenames to
upper filenames. The function correctly passes up lower filenames,
unchanged, when filename encryption isn't in use. However, it was also
passing up lower filenames when the filename wasn't encrypted or
when decryption failed. Since 88ae4ab980, eCryptfs refuses to lookup
lower plaintext names when filename encryption is enabled so this
resulted in a situation where userspace would see lower plaintext
filenames in calls to getdents(2) but then not be able to lookup those
filenames.
An example of this can be seen when enabling filename encryption on an
eCryptfs mount at the root directory of an Ext4 filesystem:
$ ls -1i /lower
12 ECRYPTFS_FNEK_ENCRYPTED.FWYZD8TcW.5FV-TKTEYOHsheiHX9a-w.NURCCYIMjI8pn5BDB9-h3fXwrE--
11 lost+found
$ ls -1i /upper
ls: cannot access '/upper/lost+found': No such file or directory
? lost+found

With this change, the lower lost+found dentry is ignored:
$ ls -1i /lower
12 ECRYPTFS_FNEK_ENCRYPTED.FWYZD8TcW.5FV-TKTEYOHsheiHX9a-w.NURCCYIMjI8pn5BDB9-h3fXwrE--
11 lost+found
$ ls -1i /upper
12 test
Additionally, some potentially noisy error/info messages in the related
code paths are turned into debug messages so that the logs can't be
easily filled.

- The address should not set any bits beyond the processor's

commit 37ff02acaa upstream.
Enabling virtual mapped kernel stacks breaks the thunderx_zip
driver. On compression or decompression the executing CPU hangs
in an endless loop. The reason for this is the usage of __pa
by the driver which does no longer work for an address that is
not part of the 1:1 mapping.
The zip driver allocates a result struct on the stack and needs
to tell the hardware the physical address within this struct
that is used to signal the completion of the request.
As the hardware gets the wrong address after the broken __pa
conversion it writes to an arbitrary address. The zip driver then
waits forever for the completion byte to contain a non-zero value.
Allocating the result struct from 1:1 mapped memory resolves this
bug.
