Commit 4104d326b670 ("ftrace: Remove global function list and call function
directly") simplified the ftrace code by removing the global_ops list with a
new design. But this cleanup also broke the filtering of PIDs that are added
to the set_ftrace_pid file.
Add back the proper hooks to have pid filtering working once again.

T3 HW only supports 32 bit MRs. If the system uses 64 bit memory
addresses, then a registered 32 bit MR will wrap and write to the
wrong memory when used with addresses > 4GB. To prevent this,
simply fail to allocate an MR on 64 bit machines (other means
of registering memory are still available and software can still
work, we just don't allow this means of memory registration).

DMA transfers must be greater than the watermark level size. spi_imx->rx_wml

spi_transfer contains the transfer len in bytes. Fix the check if DMA is
possible for a transfer accordingly. This fixes transfers with sizes between

Device tree provides option to specify the max freqency with property
"max-frequency" in dts and common parse function mmc_of_parse() will
parse it and use this value to set host->f_max to tell the MMC core
the maxinum frequency the host works.
However, current sdhci driver will finally overwrite this value with
host->max_clk regardless of the max-frequency property.
This patch makes sure not overwrite the max-frequency set from device
tree and do basic sanity check.

This is an incremental fix of commit
e62bd351b("mmc: sdhci-esdhc-imx: Do not break platform data boards").
After commit 8d86e4fcccf6 ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()"),
we do not need to run the check of boarddata->wp_type/cd_type/max_bus_width
again for dt platform since those are already handled by mmc_of_parse().
Current code only exclude the checking of wp_type for dt platform which
does not make sense.
This patch moves all non dt probe code into one function.
Besides, since we only support SD3.0/eMMC HS200 for dt platform, the
support_vsel checking and ultra high speed pinctrl state are also merged
into sdhci_esdhc_imx_probe_dt.
Then we have two separately probe function for dt and non dt type.
This can make the driver probe more clearly.

Current card detect probe process is that when driver finds a valid
ESDHC_CD_GPIO, it will clear the quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION
which is set by default for all esdhc/usdhc controllers.
Then host driver will know there's a valid card detect function.
Commit 8d86e4fcccf6 ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()")
breaks GPIO CD function for dt platform that it will return directly
when find ESDHC_CD_GPIO for dt platform which result in the later wrongly
to keep SDHCI_QUIRK_BROKEN_CARD_DETECTION for all dt platforms.
Then MMC_CAP_NEEDS_POLL will be used instead even there's a valid
GPIO card detect.
This patch adds back this function and follows the original approach to
clear the quirk if find an valid CD GPIO for dt platforms.

Sometimes BADA, DEB or CEB error interrupts occur when sd card is
unplugged during data transfer. These interrupts are currently ignored
by the interrupt handler. But, this results in card not being
recognised on subsequent insertion. This is because mmcqd is waiting
forever for the data transfer(for which error occurred) to complete.
Fix this, by reporting BADA, DEB, CEB errors to mmc-core as -EILSEQ, so
that the core can do appropriate handling.

DTO/DCRC errors were not being informed to the mmc core since
commit ae4bf788ee9b ("mmc: omap_hsmmc: consolidate error report handling of
HSMMC IRQ"). This commit made sure 'end_trans' is never set on DTO/DCRC
errors. This is because after this commit 'host->data' is checked after
it has been cleared to NULL by omap_hsmmc_dma_cleanup().
Because 'end_trans' is never set, omap_hsmmc_xfer_done() is never invoked
making core layer not to be aware of DTO/DCRC errors. Because of this
any command invoked after DTO/DCRC error leads to a hang.
Fix this by checking for 'host->data' before it is actually cleared.
