Renesas boards were consistently defaulting to the 1024x768 resolution,
regardless of the native resolution of the monitor plugged in. It was
determined that the EDID of the monitor was not being read. Since the
DAC is a shared line, in order to read from or write to it we must take
control of the DAC clock. This can be done by setting the proper
register to one.
This bug fix sets the register MGA1064_GEN_IO_CTL2 to one. The DAC
control line can be used to determine whether or not a new monitor has
been plugged in. But since the hotplug feature is not one we will
support, it has been decided to simply leave the register set to one.

A monitor or a user could request a resolution greater than the
available VRAM for the backing framebuffer. This change checks the
required framebuffer size against the max VRAM size and rejects modes
if they are too big. This change can also remove a mode request passed
in via the video= parameter.

kernel_map_sync_memtype() is called from a variety of contexts. The
pat.c code that calls it seems to ensure that it is not called for
non-ram areas by checking via pat_pagerange_is_ram(). It is important
that it only be called on the actual identity map because there *IS*
no map to sync for highmem pages, or for memory holes.
The ioremap.c uses are not as careful as those from pat.c, and call
kernel_map_sync_memtype() on PCI space which is in the middle of the
kernel identity map _range_, but is not actually mapped.
This patch adds a check to kernel_map_sync_memtype() which probably
duplicates some of the checks already in pat.c. But, it is necessary
for the ioremap.c uses and shouldn't hurt other callers.
I have reproduced this bug and this patch fixes it for me and the
original bug reporter:

Commit 37706996 "mlx4_en: fix allocation of CPU affinity reverse-map" fixed
a bug when mlx4_dev->caps.comp_pool is larger from the device rx rings, but
introduced a regression.
When the mlx4_core is activating its "legacy mode" (e.g when running in SRIOV
mode) w.r.t to EQs/IRQs usage, comp_pool becomes zero and we're crashing on
divide by zero alloc_cpu_rmap.
Fix that by enabling RFS only when running in non-legacy mode.

The set_param_l function assumes casting a u64 pointer to a u32 pointer
allows to access the lower 32bits, but it results in writing the upper
32 bits on big endian systems.
The fixed function reads the upper 32 bits of the 64 argument, and or's
them with the 32 bits of the 32-bit value passed to the function.
Since this is now a "read-modify-write" operation, we got many
"unintialized variable" warnings which needed to be fixed as well.

Hmm. I'm not sure whether these should be called "fixes", and it
probably should have gone in the merge window. But I'll let it slide.

====================
For the 57766 devices with no NVRAM, there is not enough space for the complete
boot code with EEE support. On these devices, the tg3 driver has to download
a service patch firmware to the scratchpad for the boot code to execute. This
patchset adds support to do the above.
A major portion of this patchset is refactoring the existing firmware download
section to allow a cleaner merge of the 57766 download. The 57766 firmware
differs from previous firmware in that it's not written to a contiguous area in
memory. It consists of multiple fragments to be written to different locations.
The patchset makes an attempt to make the new firmware format to be an
extension of the existing format.

This patch downloads the EEE service patch firmware and enables the necessary
EEE flags.

This lays the ground work to download the 57766 fragmented firmware. We
loop until we've written data equal to tp->fw->size minus headers.

The current firmware header parsing is complicated due to interpreting it as a
u32 array and accessing header members via array offsets. Add tg3_firmware_hdr
structure to access the firmware fields instead of hardcoding offsets. The same
header format will be used for individual firmware fragments in the 57766.
The fw_hdr and tg3 structures have all the information required for
loading the fw. Remove the redundant fw_info structure and pass fw_hdr
instead.

For completeness and consistency, add common function
tg3_pause_cpu_and_set_pc(). This is only for existing fw and not used for the
57766.

The 57766 rxcpu needs to be paused/resumed when we download the firmware just
like we do for existing firmware. Refactor the pause/resume code to be
reusable.
This patch also renames the "offset" argument of tg3_halt_cpu to "cpu_base"
since that's what it really is.

tg3 used the fw_needed member loosely as a synonym for firmware TSO. Now
that the 57766 needs firmware download support, fw_needed can no longer be
used like this. This patch creates a new FW_TSO flag and changes the
code to use it.
Also rearrange all the TSO flags together in the enum.

====================
This is a short series that now allows mac filter programming on any
card that support IFF_UNICAST_FLT by using the existing FDB interface.
Some existing drivers that had FDB functionality usually supported
it only in SR-IOV mode. Since that's not always enabled, and
we want to take advantage of IFF_UNICAST_FLT support, these drivers
have been converted to call the default handler when not in SRIOV mode.

Allow qlcnic to use the generic fdb handler when the driver options
are not enabled. Untill the driver is fully fixed, this allows
the use of the FDB interface with qlogic driver, but simply puts
the driver into promisc mode since the driver currently does not
support IFF_UNICAST_FLT.

For fdb_add, use the default handler in the non-SRIOV case.
For the other fdb handlers, just remove them and use the
default ones.

If the driver does not support the ndo_op use the generic
handler for it. This should work in the majority of cases.
Eventually the fdb_dflt_add call gets translated into a
__dev_set_rx_mode() call which should handle hardware
support for filtering via the IFF_UNICAST_FLT flag.
Namely IFF_UNICAST_FLT indicates if the hardware can do
unicast address filtering. If no support is available
the device is put into promisc mode.

Allocating 2 buffers per page is insanely inefficient when MTU is 1500
and PAGE_SIZE is 64K (as it usually is on POWER). Allocate as many as
we can fit, and choose the refill batch size at run-time so that we
still always use a whole page at once.
