Currently, PRI capability checks are repeated across all PRI API's.
Instead, cache the capability check result in pci_pri_init() and use it
in other PRI API's.

Please fix the typo spotted by Sergei.
With commit 83293386bc95 ("mmc: core: Prevent processing SDIO IRQs
when the card is suspended") SDIO interrupts are dropped if they
occur while the card is suspended. Dropping the interrupts can cause
problems after resume with cards that remain powered during suspend
and preserve their state.
Move the code to get pending SDIO interrupts from
process_sdio_pending_irqs() to a dedicated function.

Maybe it will be better to move this define out of ifdef, i.e.:
#ifdef CONFIG_BUG
...
-#define BUG_ON()...
...
#else
...
-#define BUG_ON()...
...
#endif
+#define BUG_ON()...
I can prepare a patch if you think it worth it.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct spider_net_card {
...
struct spider_net_descr darray[0];
};

The merge_config.sh script verifies that all the config options have
their expected value in the resulting file and prints any issues as
warnings. These checks aren't intended to be treated as errors given
the current implementation. However, since "set -e" was added, if the

The device-tree properties documentation-file specifies the property
"microchip,spi-present-mask" as required for MCP23SXX chips. However,
the device-tree-source example below it uses only "spi-present-mask".
Without "microchip," on the front, the driver will print "missing
spi-present-mask" when

Resubmit it when you test it properly on current kernels.

I normally would do more diligence on this, but the timing is such

The placement of the lock member in mm_context_t suggests that it is
used to protect the vdso* members, but AFAICT, it is only ever used
under #ifdef CONFIG_MODIFY_LDT_SYSCALL. So guarding the member by the
same config option is a cheap way to reduce sizeof(mm_struct) by 32
bytes (only for
