mm: fix the TLB range flushed when __tlb_remove_page() runs out of slots

commit e6c495a96ce02574e765d5140039a64c8d4e8c9e upstream.

zap_pte_range loops from @addr to @end.  In the middle, if it runs out of
batching slots, TLB entries needs to be flushed for @start to @interim,
NOT @interim to @end.

Since ARC port doesn't use page free batching I can't test it myself but
this seems like the right thing to do.

Observed this when working on a fix for the issue at thread:

iser-target: Fix isert_put_reject payload buffer post

commit 3df8f68aaf7ebe3d136a22262b41b350b0a1858b upstream.

This patch adds the missing isert_put_reject() logic to post
a outgoing payload buffer to hold the 48 bytes of original PDU
header request payload for the rejected cmd.

It also fixes ISTATE_SEND_REJECT handling in isert_response_completion()
-> isert_do_control_comp() code, and drops incorrect iscsi_cmd_t->reject_comp
usage.

iser-target: Fix session reset bug with RDMA_CM_EVENT_DISCONNECTED

commit b2cb96494d83b894a43ba8b9023eead8ff50684b upstream.

This patch addresses a bug where RDMA_CM_EVENT_DISCONNECTED may occur
before the connection shutdown has been completed by rx/tx threads,
that causes isert_free_conn() to wait indefinately on ->conn_wait.

This patch allows isert_disconnect_work code to invoke rdma_disconnect
when isert_disconnect_work() process context is started by client
session reset before isert_free_conn() code has been reached.

It also adds isert_conn->conn_mutex protection for ->state within
isert_disconnect_work(), isert_cq_comp_err() and isert_free_conn()
code, along with isert_check_state() for wait_event usage.

(v2: Add explicit iscsit_cause_connection_reinstatement call
     during isert_disconnect_work() to force conn reset)

firewire: fix libdc1394/FlyCap2 iso event regression

commit 0699a73af3811b66b1ab5650575acee5eea841ab upstream.

Commit 18d627113b83 (firewire: prevent dropping of completed iso packet
header data) was intended to be an obvious bug fix, but libdc1394 and
FlyCap2 depend on the old behaviour by ignoring all returned information
and thus not noticing that not all packets have been received yet.  The
result was that the video frame buffers would be saved before they
contained the correct data.

Reintroduce the old behaviour for old clients.

ARM: 7722/1: zImage: Convert 32bits memory size and address from ATAG to 64bits DTB

commit faefd550c45d8d314e8f260f21565320355c947f upstream.

When CONFIG_ARM_APPENDED_DTB is selected, if the bootloader provides
an ATAG_MEM it replaces the memory size and the memory address in the
memory node of the device tree. In the case of a system which can
handle more than 4GB, the memory node cell size is 4: each data
(memory size and memory address) are 64 bits and then use 2 cells.

The current code in atags_to_fdt.c made the assumption of a cell size
of 2 (one cell for the memory size and one cell for the memory
address), this leads to an improper write of the data and ends with a
boot hang.

This patch writes the memory size and the memory address on the memory
node in the device tree depending of the size of the memory node (32
bits or 64 bits).

It has been tested in the 2 cases:
- with a dtb using skeleton.dtsi
- and with a dtb using skeleton64.dtsi

SCSI: isci: Fix a race condition in the SSP task management path

commit 96f15f29038e58e1b0a96483e2b369ff446becf1 upstream.

This commit fixes a race condition in the isci driver abort task and SSP
device task management path.  The race is caused when an I/O termination
in the SCU hardware is necessary because of an SSP target timeout condition,
and the check of the I/O end state races against the HW-termination-driven
end state.  The failure of the race meant that no TMF was sent to the device
to clean-up the pending I/O.

SCSI: sd: fix crash when UA received on DIF enabled device

commit 085b513f97d8d799d28491239be4b451bcd8c2c5 upstream.

sd_prep_fn will allocate a larger CDB for the command via mempool_alloc
for devices using DIF type 2 protection.  This CDB was being freed
in sd_done, which results in a kernel crash if the command is retried
due to a UNIT ATTENTION.  This change moves the code to free the larger
CDB into sd_unprep_fn instead, which is invoked after the request is
complete.

It is no longer necessary to call scsi_print_command separately for
this case as the ->cmnd will no longer be NULL in the normal code path.

Also removed conditional test for DIF type 2 when freeing the larger
CDB because the protection_type could have been changed via sysfs while
the command was executing.

tracing: Fix error handling to ensure instances can always be removed

commit 609e85a70bcd0eedf4ec60639dbcfb1ab011e054 upstream.

Remove debugfs directories for tracing instances during creation if an error
occurs causing the trace_array for that instance to not be added to
ftrace_trace_arrays. If the directory continues to exist after the error, it
cannot be removed because the respective trace_array is not in
ftrace_trace_arrays.
