Hello!
I'm trying to compile the kernel for a rk3288-firefly, but I'm having some making errors.

Please, I would appreciate any help with this matter.

Here you can find some information about the OS and the machine, and a summary of the build/mk-kernel.sh rk3288-firefly output (only the error messages)

Asus Core i5. x86_64 GNU/Linux

$ sudo build/mk-kernel.sh rk3288-firefly

l2tp: fix tunnel lookup use-after-free race
28f5bfb 
l2tp_tunnel_get walks the tunnel list to find a matching tunnel
instance and if a match is found, its refcount is increased before
returning the tunnel pointer. But when tunnel objects are destroyed,
they are on the tunnel list after their refcount hits zero. Fix this
by moving the code that removes the tunnel from the tunnel list from
the tunnel socket destructor into in the l2tp_tunnel_delete path,
before the tunnel refcount is decremented.

refcount_t: increment on 0; use-after-free.

blktrace: fix unlocked registration of tracepoints
28de938 
commit a6da002 upstream.

We need to ensure that tracepoints are registered and unregistered
with the users of them. The existing atomic count isn't enough for
that. Add a lock around the tracepoints, so we serialize access
to them.

This fixes cases where we have multiple users setting up and
tearing down tracepoints, like this:

mm: shmem.c: Correctly annotate new inodes for lockdep
4da7f35 
commit b45d71f upstream.

Directories and inodes don't necessarily need to be in the same lockdep
class.  For ex, hugetlbfs splits them out too to prevent false positives
in lockdep.  Annotate correctly after new inode creation.  If its a
directory inode, it will be put into a different class.

This should fix a lockdep splat reported by syzbot:

s390/kasan: increase instrumented stack size to 64k
9fed920 
Increase kasan instrumented kernel stack size from 32k to 64k. Other
architectures seems to get away with just doubling kernel stack size under
kasan, but on s390 this appears to be not enough due to bigger frame size.
The particular pain point is kasan inlined checks (CONFIG_KASAN_INLINE
vs CONFIG_KASAN_OUTLINE). With inlined checks one particular case hitting
stack overflow is fs sync on xfs filesystem:

perf annotate: AArch64 support
0fcb1da 
This is a regex converted version from the original:

	https://lkml.org/lkml/2016/5/19/461

Add basic support to recognise AArch64 assembly. This allows perf to
identify AArch64 instructions that branch to other parts within the
same function, thereby properly annotating them.

Rebased onto new cross-arch annotation bits:

powerpc/powernv: Use kernel crash path for machine checks
6fcd6ba 
There are quite a few machine check exceptions that can be caused by
kernel bugs. To make debugging easier, use the kernel crash path in
cases of synchronous machine checks that occur in kernel mode, if that
would not result in the machine going straight to panic or crash dump.

There is a downside here that die()ing the process in kernel mode can
still leave the system unstable. panic_on_oops will always force the
system to fail-stop, so systems where that behaviour is important will
still do the right thing.

As a test, when triggering an i-side 0111b error (ifetch from foreign
address) in kernel mode process context on POWER9, the kernel currently
dies quickly like this:

  Severe Machine check interrupt [Not recovered]
    NIP [ffff000000000000]: 0xffff000000000000

After this patch, the process is killed and the kernel continues with
this message, which gives enough information to identify the offending
branch (i.e., with CFAR):

blktrace: fix unlocked registration of tracepoints
a6da002 
We need to ensure that tracepoints are registered and unregistered
with the users of them. The existing atomic count isn't enough for
that. Add a lock around the tracepoints, so we serialize access
to them.

This fixes cases where we have multiple users setting up and
tearing down tracepoints, like this:

mm: shmem.c: Correctly annotate new inodes for lockdep
b441ed6 
commit b45d71f upstream.

Directories and inodes don't necessarily need to be in the same lockdep
class.  For ex, hugetlbfs splits them out too to prevent false positives
in lockdep.  Annotate correctly after new inode creation.  If its a
directory inode, it will be put into a different class.

This should fix a lockdep splat reported by syzbot:

llc: better deal with too small mtu

syzbot loves to set very small mtu on devices, since it brings joy.
We must make llc_ui_sendmsg() fool proof.

mm: shmem.c: Correctly annotate new inodes for lockdep
b45d71f 
Directories and inodes don't necessarily need to be in the same lockdep
class.  For ex, hugetlbfs splits them out too to prevent false positives
in lockdep.  Annotate correctly after new inode creation.  If its a
directory inode, it will be put into a different class.

This should fix a lockdep splat reported by syzbot:

Add support for f2fs and it's dependency crc32 to rock64.

This patch may or may not need to be included as well due to this bug https://bugs.debian.org/819725    A official patch was added by Debian https://salsa.debian.org/kernel-team/linux/blob/master/debian/patches/bugfix/all/fs-add-module_softdep-declarations-for-hard-coded-cr.patch

external: defconfig: Make crc, crc32, f2fs to be compiled into kernel. (rockchip-linux#35)

This changes crc, crc32, and f2fs to be compiled into the kernel instead of as module. This also fixes the issue of crc32-arm64 not being compiled due to a incorrect driver name.  CONFIG_CRYPTO_CRC32_ARM64 became CONFIG_CRYPTO_CRC32_ARM64_CE in newer kernel sources. That's why I had to change that here.

A pending hrtimer may expire after the kthread_worker of tcpm port

arm64: dts: meson-sm1-odroid: use correct enable-gpio pin for tf-io r…
162f805 
…egulator

[ Upstream commit 323ca76 ]

The interrupt pin of the external ethernet phy is used, instead of the
enable-gpio pin of the tf-io regulator. The GPIOE_2 pin is located in
the gpio_ao bank.

This causes phy interrupt problems at system startup.
