arm64: dts: qcom: sm8550: Use the correct LLCC register scheme

2023-06-21T14:02:18+00:00

commit 661a4f089317c877aecd598fb70cd46510cc8d29 upstream.

During the ABI-breaking (for good reasons) conversion of the LLCC
register description, SM8550 was not taken into account, resulting
in LLCC being broken on any kernel containing the patch referenced
in the fixes tag.

Fix it by describing the regions properly.

parisc: Delete redundant register definitions in

2023-06-21T14:02:18+00:00

commit b5b2a02bcaac7c287694aa0db4837a07bf178626 upstream.

We define sp and ipsw in  using ".reg", and when using
current binutils (snapshot 2.40.50.20230611) the definitions in
 using "=" conflict with those:

arch/parisc/include/asm/assembly.h: Assembler messages:
arch/parisc/include/asm/assembly.h:93: Error: symbol `sp' is already defined
arch/parisc/include/asm/assembly.h:95: Error: symbol `ipsw' is already defined

Delete the duplicate definitions in .

Also delete the definition of gp, which isn't used anywhere.

powerpc/purgatory: remove PGO flags

commit 20188baceb7a1463dc0bcb0c8678b69c2f447df6 upstream.

If profile-guided optimization is enabled, the purgatory ends up with
multiple .text sections.  This is not supported by kexec and crashes the
system.

commit 41efbb682de1231c3f6361039f46ad149e3ff5b9 upstream.

The debugfs_create_dir() returns ERR_PTR in case of an error and the
correct way of checking it is using the IS_ERR_OR_NULL inline function
rather than the simple null comparision. This patch fixes the issue.

commit 85041e12418fd0c08ff972b7729f7971afb361f8 upstream.

The given value of 1518 seems to refer to the layer 2 ethernet frame
size without 802.1Q tag. Actual use of the "max-frame-size" including in
the consumer of the "altr,tse-1.0" compatible is the MTU.

mips: Move initrd_start check after initrd address sanitisation.

2023-06-21T14:02:07+00:00

[ Upstream commit 4897a898a216058dec55e5e5902534e6e224fcdf ]

PAGE_OFFSET is technically a virtual address so when checking the value of
initrd_start against it we should make sure that it has been sanitised from
the values passed by the bootloader. Without this change, even with a bootloader
that passes correct addresses for an initrd, we are failing to load it on MT7621
boards, for example.

[ Upstream commit 2d645604f69f3a772d58ead702f9a8e84ab2b342 ]

Various fixes for the Au1200/Au1550/Au1300 DBDMA2 code:

- skip cache invalidation if chip has working coherency circuitry.
- invalidate KSEG0-portion of the (physical) data address.
- force the dma channel doorbell write out to bus immediately with
  a sync.
