After commit 8d86e4fc ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()"), we do not need those duplicated parsing anymore. Note: fsl,cd-controller is also deleted due to the driver does not support controller card detection anymore after switch to runtime pm. And there's no user of it right now in device tree. wp-gpios is kept because we're still support fsl,wp-controller, so we need a way to check if it's gpio wp or controller wp.

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 8d86e4fc ("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 8d86e4fc ("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 ae4bf788 ("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.

The FPU rewrite removed the dynamic allocations of 'struct fpu'. But, this potentially wastes massive amounts of memory (2k per task on systems that do not have AVX-512 for instance). Instead of having a separate slab, this patch just appends the space that we need to the 'task_struct' which we dynamically allocate already. This saves from doing an extra slab allocation at fork(). The only real downside here is that we have to stick everything and the end of the task_struct. But, I think the BUILD_BUG_ON()s I stuck in there should keep that from being too fragile.

In CMA, 1 bit in bitmap means 1 << order_per_bits pages so size of bitmap is cma->count >> order_per_bits rather than just cma->count. This patch fixes it.

CMA has alloc/free interface for debugging. It is intended that alloc/free occurs in specific CMA region, but, currently, alloc/free interface is on root dir due to the bug so we can't select CMA region where alloc/free happens. This patch fixes this problem by making alloc/free interface per CMA region.

Currently, we set wrong gfp_mask to page_owner info in case of isolated freepage by compaction and split page. It causes incorrect mixed pageblock report that we can get from '/proc/pagetypeinfo'. This metric is really useful to measure fragmentation effect so should be accurate. This patch fixes it by setting correct information. Without this patch, after kernel build workload is finished, number of mixed pageblock is 112 among roughly 210 movable pageblocks. But, with this fix, output shows that mixed pageblock is just 57.
