Some relative codes,
such as 'zone_page_state_add(1, zone, NR_SLAB_RECLAIMABLE);',
caused compile errors, when compiled with clang.
The corresponding interface(NR_SLAB_RECLAIMABLE, et.) was changed
between kernel v4.4 and v4.19.
These codes were used to updates the cachelines with the statistics,
and are removed in Midgard DDK r22.
Here, I remove them too, in current Midgard DDK r18.

user_atom.atom_number can be indirectly controlled by user-space,
hence leading to a potential exploitation
of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/gpu/arm/midgard/mali_kbase_jd.c:1397 kbase_jd_submit() warn:
potential spectre issue 'jctx->atoms' [r]
katom = &jctx->atoms[user_atom.atom_number];
Fix this by sanitizing user_atom.atom_number
before 'katom = &jctx->atoms[user_atom.atom_number];'.
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

The process to get current source code under midgard_for_linux/ :
1. On the status of commit 18166b65,
revert commit "91842c9 MALI: rockchip: upgrade midgard DDK to r18p0-01rel0",
which upgraded drivers/gpu/arm/midgard/ from DDK r14 to r18.
2. copy directory drivers/gpu/arm/midgard/ to drivers/gpu/arm/midgard_for_linux/.
It's ensured that changes of commits in drivers/gpu/arm/midgard/
from RK power management group early than commit 18166b65
are correspondingly remained in current drivers/gpu/arm/midgard_for_linux/.
