Device drivers typically use ACPI _HIDs/_CIDs listed in struct device_driver

do not have _CID (e.g. SATA, USB). Instead, we can leverage ACPI

Rather than parsing /proc/pid/status file one line at a time, read
it into a buffer in one shot and search for all strings in one pass.
tgid conversion also simplified -- removing the isspace walk. As
noted by Arnaldo those are not needed for atoi == strtol calls.

The above is the killer for Samba. If fincore
returns true but when we schedule the pread
we block, we're hosed.
Once we block, we're done

insert_inline_extent() checked for compressed_pages to be NULL then
it accessed it under compress_type != BTRFS_COMPRESS_NONE.
This patch adds BUG() when compress_size != 0, compress_type !=
BTRFS_COMPRESS_NONE and compresses_pages == 0.

Refactor the code in order to remove the global variables and split the clock
source and clock events registration in order to ease the addition of the clock
notifiers needed to handle the parent clock rate changes.

The dw_apb_timer_of timer is using __raw_readl to access the timer
register, which is causing issues when the system is running in
big endian mode. Fix this by using readl_relaxed() which should
account for the endian settings.
This fixes issues where the time jumps around in

sun6i and newer have an arm arch timer which is a better sched_clock source
then the sun4i-timer, and sched_clock does not have priorities, so do not
register the sun4i-timer sched_clock at all on sun6i and newer.

The parent clock of the sun5i timer is the AHB clock, which rate might change
because of other devices requirements.
This is for example the case on the Allwinner A31, where the DMA controller
