441c938168 tty: vt: replace BUG_ON() by WARN_ON_ONCE()
No need to panic in vc_uniscr_copy_line(), just warn. This should never
happen though, as vc_uniscr_check() is supposed to be called before
vc_uniscr_copy_line(). And the former checks vc->vc_uni_lines already.

In any case, use _ONCE as vc_uniscr_copy_line() is called repeatedly for
each line. So don't flood the logs, just in case.

feb36abbed tty: vt: remove struct uni_screen
It contains only lines with pointers to characters (u32s). So use
simple clear 'u32 **lines' all over the code.

This avoids zero-length arrays. It also makes the allocation less
error-prone (size of the struct wasn't taken into account at all).

c4c81db5cf tty: serial: fsl_lpuart: disable the CTS when send break signal
LPUART IP has a bug that it treats the CTS as higher priority than the
break signal, which cause the break signal sending through UARTCTRL_SBK
may impacted by the CTS input if the HW flow control is enabled.

Add this workaround patch to fix the IP bug, we can disable CTS before
asserting SBK to avoid any interference from CTS, and re-enable it when
break off.

Such as for the bluetooth chip power save feature, host can let the BT
chip get into sleep state by sending a UART break signal, and wake it up
by turning off the UART break. If the BT chip enters the sleep mode
successfully, it will pull up the CTS line, if the BT chip is woken up,
it will pull down the CTS line. If without this workaround patch, the
UART TX pin cannot send the break signal successfully as it affected by
the BT CTS pin. After adding this patch, the BT power save feature can
work well.

98a59cd26e serial: liteuart: drop obsolete dependency on COMPILE_TEST
Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

2ee91d42bf serial: liteuart: move tty_flip_buffer_push() out of rx loop
Calling tty_flip_buffer_push() for each individual received character
is overkill. Move it out of the rx loop, and only call it once per
set of characters received together.

4f43ade45d memblock: always release pages to the buddy allocator in memblock_free_late()
If CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, memblock_free_pages()
 only releases pages to the buddy allocator if they are not in the
 deferred range. This is correct for free pages (as defined by
 for_each_free_mem_pfn_range_in_zone()) because free pages in the
 deferred range will be initialized and released as part of the deferred
 init process. memblock_free_pages() is called by memblock_free_late(),
 which is used to free reserved ranges after memblock_free_all() has
 run. All pages in reserved ranges have been initialized at that point,
 and accordingly, those pages are not touched by the deferred init
 process. This means that currently, if the pages that
 memblock_free_late() intends to release are in the deferred range, they
 will never be released to the buddy allocator. They will forever be
 reserved.
 
 In addition, memblock_free_pages() calls kmsan_memblock_free_pages(),
 which is also correct for free pages but is not correct for reserved
 pages. KMSAN metadata for reserved pages is initialized by
 kmsan_init_shadow(), which runs shortly before memblock_free_all().
 
 For both of these reasons, memblock_free_pages() should only be called
 for free pages, and memblock_free_late() should call __free_pages_core()
 directly instead.
 
 One case where this issue can occur in the wild is EFI boot on
 x86_64. The x86 EFI code reserves all EFI boot services memory ranges
 via memblock_reserve() and frees them later via memblock_free_late()
 (efi_reserve_boot_services() and efi_free_boot_services(),
 respectively). If any of those ranges happens to fall within the
 deferred init range, the pages will not be released and that memory will
 be unavailable.
 
 For example, on an Amazon EC2 t3.micro VM (1 GB) booting via EFI:
 
 v6.2-rc2:
 Node 0, zone      DMA
       spanned  4095
