Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

xen: pvblock: fix the maximum io size in one operation

2023-11-29T14:32:15+00:00

The current implementation may cause BUG_ON() in blkfront_aio()
	BUG_ON(n > BLKIF_MAX_SEGMENTS_PER_REQUEST);

In pvblock_iop(), a read/write operation will be split into smaller
chunks of data so that the size in one access (aio_nbytes) is limited
to, at the maximum,
	BLKIF_MAX_SEGMENTS_PER_REQUEST * PAGE_SIZE

But this works only if when the *buffer* passed in to pvblock_io()
is page-aligned. If not, the given data region may stand across
(BLKIF_MAX_SEGMENTS_PER_REQUEST + 1) pages. See the logic in
blkfront_aio():
	start = (uintptr_t)aiocbp->aio_buf & PAGE_MASK;
	end = ((uintptr_t)aiocbp->aio_buf + aiocbp->aio_nbytes +
	       PAGE_SIZE - 1) & PAGE_MASK;
Then this will lead to BUG_ON() above.

This can be fixed by decreasing the maximum size of aio_nbytes.

The return value is not used for anythig, and in a later patch the

blk: Switch over to using uclass IDs

2022-09-16T15:05:16+00:00

We currently have an if_type (interface type) and a uclass id. These are
closely related and we don't need to have both.

Drop the if_type values and use the uclass ones instead.

Maintain the existing, subtle, one-way conversion between UCLASS_USB and
UCLASS_MASS_STORAGE for now, and add a comment.
