I would just prefer if you put a comment into place where we used to
take a reference to parent so that it is more obvious in the code.

The Linux mutex code has a MUTEX_SPIN_ON_OWNER configuration

Currently one range is allocated below 896MB (and not 4G). So if we extend

Commit 7517de348663b08a808aff44b5300e817157a568 ("MIPS: Alchemy: Redo
PCI as platform driver") added a reference to CONFIG_DEBUG_PCI. Change
it to CONFIG_PCI_DEBUG, as that is a valid Kconfig macro.
Also add a newline to a debugging printk that this fix enables.

Reserving a large number of 1GB hugetlbfs pages at boot takes a very
long time due to the pages being memset to 0 during the reservation.
This is unneeded as the pages will be zeroed by clear_huge_page() when
being allocated by the user.
Large system sites would at times like to allocate a very la

Using this parameter one can disable the storage_size/2 check if
he is really sure that the UEFI does sane gc.

Some (broken?) EFI implementations return always a MaximumVariableSize of 0,
check against max_size only if it is non-zero.

Normally we keep drivers in alphabetical inside Kconfig and Makefile and over
time this was broken for ARM cpufreq drivers. Fix it.
