The BAD_MADT_GICC_ENTRY() macro checks if a GICC MADT entry passes
muster from an ACPI specification standpoint. Current macro detects the
MADT GICC entry length through ACPI firmware version (it changed from 76
to 80 bytes in the transition from ACPI 5.1 to ACPI 6.0 specification)
but always uses (erroneously) the ACPICA (latest) struct (ie struct
acpi_madt_generic_interrupt - that is 80-bytes long) length to check if
the current GICC entry memory record exceeds the MADT table end in
memory as defined by the MADT table header itself, which may result in
false negatives depending on the ACPI firmware version and how the MADT
entries are laid out in memory (ie on ACPI 5.1 firmware MADT GICC
entries are 76 bytes long, so by adding 80 to a GICC entry start address
in memory the resulting address may well be past the actual MADT end,
triggering a false negative).
Fix the BAD_MADT_GICC_ENTRY() macro by reshuffling the condition checks
and update them to always use the firmware version specific MADT GICC
entry length in order to carry out boundary checks.

Commit 4e552c8cb5 ("leds: add LED_ON brightness as boolean value")
has introduced the LED_ON enumeration value that can be used
instead of LED_FULL which has more of a linear value.
Because the tm2-touchscreen doesn't have brightness levels, but
it's a simple on/off led, use LED_ON instead of LED_FULL.

Commit 9fdca4da4d (IB/SA: Split struct sa_path_rec based on IB and
ROCE specific fields) moved the service_id to be specific attribute
for IB and OPA SA Path Record, and thus wasn't assigned for RoCE.
This caused to the following kernel panic in the CMA request handler flow:

This patch moves it back to the common SA Path Record structure
and removes the redundant setter and getter.
Tested on Connect-IB and Connect-X4 in Infiniband and RoCE respectively.

This change will optimize kernel memory deregistration operations.
__ib_umem_release() used to call set_page_dirty_lock() against every
writable page in its memory region. Its purpose is to keep data
synced between CPU and DMA device when swapping happens after mem
deregistration ops. Now we choose not to set page dirty bit if it's
already set by kernel prior to calling __ib_umem_release(). This
reduces memory deregistration time by half or even more when we ran
application simulation test program.

Commit 5752075144 ("IB/SA: Add OPA path record type") introduced
new local function __ib_copy_path_rec_to_user, but didn't limit its
scope. This produces the following sparse warning:
drivers/infiniband/core/uverbs_marshall.c:99:6: warning:
symbol '__ib_copy_path_rec_to_user' was not declared. Should it be
static?
In addition, it used sizeof ... notations instead of sizeof(...), which
is correct in C, but a little bit misleading. Let's change it too.

The cited patch added a type field to structures ib_ah and rdma_ah_attr.
Function mlx4_ib_query_ah() builds an rdma_ah_attr structure from the
data in an mlx4_ib_ah structure (which contains both an ib_ah structure
and an address vector).
For mlx4_ib_query_ah() to work properly, the type field in the contained
ib_ah structure must be set correctly.
In the outgoing MAD tunneling flow, procedure mlx4_ib_multiplex_mad()
paravirtualizes a MAD received from a slave and sends the processed
mad out over the wire. During this processing, it populates an
mlx4_ib_ah structure and calls mlx4_ib_query_ah().
The cited commit overlooked setting the type field in the contained
ib_ah structure before invoking mlx4_ib_query_ah(). As a result, the
type field remained uninitialized, and the rdma_ah_attr structure was
incorrectly built. This resulted in improperly built MADs being sent out
over the wire.
This patch properly initializes the type field in the contained ib_ah
structure before calling mlx4_ib_query_ah(). The rdma_ah_attr structure
is then generated correctly.

The handling of IB_RDMA_WRITE_ONLY_WITH_IMMEDIATE will leak a memory
reference when a buffer cannot be allocated for returning the immediate
data.
The issue is that the rkey validation has already occurred and the RNR
nak fails to release the reference that was fruitlessly gotten. The
the peer will send the identical single packet request when its RNR
timer pops.
The fix is to release the held reference prior to the rnr nak exit.
This is the only sequence the requires both rkey validation and the
buffer allocation on the same packet.
