 Bluetooth: uart-ldisc: Fix memory leak

This is a partial, self-contained, minimal backport of commit
797fe79 upstream which fixes the memory
leak:

Bluetooth: uart-ldisc: Fix memory leak and remove destruct cb

We currently leak the hci_uart object if HCI_UART_PROTO_SET is never set
because the hci-destruct callback will then never be called.  This fix
removes the hci-destruct callback and frees the driver internal private
hci_uart object directly on tty-close. We call hci_unregister_dev() here
so the hci-core will never call our callbacks again (except destruct).
Therefore, we can safely free the driver internal data right away and
set the destruct callback to NULL.

 kernel/sys.c: fix stack memory content leak via UNAME26

Calling uname() with the UNAME26 personality set allows a leak of kernel
stack contents.  This fixes it by defensively calculating the length of
copy_to_user() call, making the len argument unsigned, and initializing
the stack buffer to zero (now technically unneeded, but hey, overkill).

 kernel/timer: Optimise apply_slack() for size and speed.

To apply proper slack, the original algorithm used to prepare a mask and
then apply the mask to obtain the appropriately rounded-off absolute
time the timer expires.

This patch modifies the masking logic to a bit-shift logic, therby
reducing the complexity and number of operations. Thus obtaining a minor
speed-up.

 slub: set slub_max_order to 0

To avoid locking and per-cpu overhead, SLUB optimisically uses
high-order allocations up to order-3 by default and falls back to lower
allocations if they fail.

So, with the default value (slub_max_order = 3), the kernel may ask up
to 3 contigous pages for each slab. However, with a reduced amount of
memory it is not worth to try to do order-3 allocations, it adds more
overhead (shrinkers have to free more objects to release any memory) and
probably, it can easily fail to success with order-3 allocations.

For this reason it is better to immediately fallback to order-0
allocations to reduce unnecessary overhead.

 ext4: enable quotas before orphan cleanup

When using quota feature we need to enable quotas before orphan cleanup
so that changes happening during it are properly reflected in quota
accounting.
