Problem:
To avoid vmalloc address space not enough caused by binder, in
following change we have increased 128mb vmalloc address space:
http://scgit.amlogic.com:8080/#/c/72977/
Solution:
Since we have back porting binder optimize from kernel 4.19 in
change:
http://scgit.amlogic.com:8080/#/c/73975/
So we can restore 240mb memory space for vmalloc

Problems:
based on android platfrom, each process may allocate 1MB vmalloc
memory space for IPC. But most process don't use full memory
range of vmalloc space. It's a waste of memory space and may
cause driver can't work normal based on 32bit kernel
Soluton:
On kernel 4.19, google have fixed it, so we need back porting

To do this without needing to dereference pointers into the

introduces a function to validate and copy binder objects

BACKPORT: binder: add functions to copy to/from binder buffers
Avoid vm_area when copying to or from binder buffers.
Instead, new copy functions are added that copy from
kernel space to binder buffer space. These use
kmap_atomic() and kunmap_atomic() to create temporary
mappings and then memcpy() is used to copy within
that page.
Also, kmap_atomic() / kunmap_atomic() use the appropriate
cache flushing to support VIVT cache architectures.
Allow binder to build if CPU_CACHE_VIVT is defined.
Several uses of the new functions are added here. More
to follow in subsequent patches.

UPSTREAM: binder: create userspace-to-binder-buffer copy function
The binder driver uses a vm_area to map the per-process
binder buffer space. For 32-bit android devices, this is
now taking too much vmalloc space. This patch removes
the use of vm_area when copying the transaction data
from the sender to the buffer space. Instead of using
copy_from_user() for multi-page copies, it now uses
binder_alloc_copy_user_to_buffer() which uses kmap()
and kunmap() to map each page, and uses copy_from_user()
for copying to that page.

binder: fix race that allows malicious free of live buffer
commit 7bada55ab5 upstream.
Malicious code can attempt to free buffers using the BC_FREE_BUFFER
ioctl to binder. There are protections against a user freeing a buffer
while in use by the kernel, however there was a window where
BC_FREE_BUFFER could be used to free a recently allocated buffer that
was not completely initialized. This resulted in a use-after-free
detected by KASAN with a malicious test program.
This window is closed by setting the buffer's allow_user_free attribute
to 0 when the buffer is allocated or when the user has previously freed
it instead of waiting for the caller to set it. The problem was that
when the struct buffer was recycled, allow_user_free was stale and set
to 1 allowing a free to go through.

This allows the context manager to retrieve information about nodes

Such information can for example be used to determine whether the
servicemanager is the only process holding a reference to a node.
This information can then be passed on to the process holding the
node, which can in turn decide whether it wants to shut down to
reduce resource usage.

There is RaceFuzzer report like below because we have no lock to close
below the race between binder_mmap and binder_alloc_new_buf_locked.
To close the race, let's use memory barrier so that if someone see
alloc->vma is not NULL, alloc->vma_vm_mm should be never NULL.
(I didn't add stable mark intentionallybecause standard android
userspace libraries that interact with binder (libbinder & libhwbinder)
prevent the mmap/ioctl race. - from Todd)

Problem:
In Jira TV-5143, final fix change have increased 128MB address space
for vmalloc. Because binder wasted too many vmalloc space but it's
hard to fix it in kernel side.
Due to incease of vmalloc address space, old design of address space
layout for KASAN32 is not suitable after this change. So we need to
change memory layout to fix this problem and let KASAN can running OK
again.
Solution:
1, rebuild address space layout for kasan
2, make kasan compatible with vmap stack config
