+Subject: [PATCH] AddressTrackerLinux: Increase the message buffer size
+
+On non-4k-page systems, the message sizes may be too large to fit into
+the buffer, resulting in MSG_TRUNC. Instead of using the fixed 4kb size,
+follow the kernel documentation guidelines as to how large the buffer
+should be.

-Subject: [PATCH] [heap] Fix saving the callee-saved registers on stack
-
-This CL reinstates the trampoline for pushing the values of
-callee-saved registers on the stack, which is used for stack scanning.
-It reintroduces the set of architecture-specific functions
-PushAllRegistersAndIterateStack, removed in crrev.com/c/3989143.
-The reason for this change is that the simpler architecture-specific
-functions SaveCalleeSavedRegisters failed to correctly save the
-values of the registers, in the presence of C++ compiler optimizations.
-
-It also removes the stack context, introduced in crrev.com/c/4017512,
-and uses again the trampoline for iterating through the stack.

-Subject: [PATCH] [heap] Move the Stack object from ThreadLocalTop to Isolate
-
-Stack information is thread-specific and, until now, it was stored in a
-field in ThreadLocalTop. This CL moves stack information to the isolate
-and makes sure to update the stack start whenever a main thread enters
-the isolate. At the same time, the Stack object is refactored and
-simplified.
-
-As a side effect, after removing the Stack object, ThreadLocalTop
-satisfies the std::standard_layout trait; this fixes some issues
-observed with different C++ compilers.
-
-Bug: v8:13630
-Bug: v8:13257

- Revert "media/gpu/v4l2VEA,IP: Workaround to USERPTR API against read-only buf"
-
- This reverts commit 203fdd03a4317f2eac57161ee101515a82df704f.
-
- Reason for revert: This workaround is no longer required because of
- the kernel patch was reverted.
-
- Original change's description:
- > media/gpu/v4l2VEA,IP: Workaround to USERPTR API against read-only buf
- >
- > VideoFrame fed in VEA::Encode() is read-only since R107 if the
- > VideoFrame has a shared memory. V4L2VideoEncodeAccelerator fails
- > because VIDOC_QBUF with USERPTR buffer fails if the pointers
- > references a read-only buffer.
- > The USERPTR API issue is apparently to be fixed by a kernel side.
- > In the meantime, this CL adds the workaround to the issue; the read
- > only buffer is copied to a writable temporary buffer every Encode
- > before VIDIOC_QBUF.
- > Not that VideoFrame has a shared memory in the case of screen share
- > because a camera stack produces GpuMemoryBuffer.
- >
- > Bug: b:243883312
- > Test: video_encode_accelerator_tests on elm, kevin and trogdor
- > Test: screen share in Google Meet on elm, kevin and trogdor
