introduced via genhd.h by the general purpose partition patch.
To fix, we just add our own MAX_MMC_PART_NAME_LEN macro instead of using
DISK_NAME_LEN.

Due to hardware bugs, some MMC host controllers don't support
multiple-block reads[1]. To resolve, add a new MMC capability flag,
MMC_CAP2_NO_MULTI_READ, which can be set by affected host controller
drivers. When this capability is set, all reads will be issued one
sector at a time.
1. See for example Advisory 2.1.1.128 "MMC: Multiple Block Read
Operation Issue" in _OMAP3530/3525/3515/3503 Silicon Errata_

This adds devicetree binding support to the ARM pl061 driver removing the

irqdomains learn dynamic irq assignment.

This simplifies the init/shutdown paths, and makes client->msgr available
during the rest of the setup process.

Initialize jump_labels much, much earlier, so they're available for use
during system setup.

When updating a newly loaded module, the code is definitely not yet
executing on any processor, so it can be updated with no need for any
heavyweight synchronization.
This patch adds arch_jump_label_static() which is implemented as
arch_jump_label_transform() by default, but architectures can override
it if it avoids, say, a call to stop_machine().

If a key has been enabled before jump_label_init() is called, don't
nop it out.
This removes arch_jump_label_text_poke_early() (which can only nop
out a site) and uses arch_jump_label_transform() instead.
