they are migrated to ZONE_MOVABLE, which also should not have pinned pages.
Remove __GFP_MOVABLE, so pages can be migrated to zones where pinning

When migration failure occurs, we still pin pages, which means
that we may pin CMA movable pages which should never be the case.
Instead return an error without pinning pages when migration failure
happens.
No need to retry migrating, because migrate_pages() already retries
10 times.

It is still possible that we pin movable CMA pages if there are isolation
errors and cma_page_list stays empty when we check again.
Check for isolation errors, and return success only when there are no
isolation errors, and cma_page_list is empty after checking.

When pages are longterm pinned, we must migrated them out of movable zone.
The function that migrates them has a hidden loop with goto. The loop is
to retry on isolation failures, and after successful migration.
Make this code better by moving this loop to the caller.

In gup_test both gup_flags and test_flags use the same flags field.
This is broken.
Farther, in the actual gup_test.c all the passed gup_flags are erased and

Which means that test_flags are ignored, and code like this always
performs pin dump test:

When pages are pinned they can be faulted in userland and migrated, and
they can be faulted right in kernel without migration.
In either case, the pinned pages must end-up being pinnable (not movable).

Hi Stefan,
Thank you for the patch! Yet something to improve:
crypto/asymmetric_keys/public_key.c:97: undefined reference to `parse_OID'
So the issue is that only ASYMMETRIC_PUBLIC_KEY_SUBTYPE is selected in
this config and the selection of OID
() usage with prb_read_valid_*()

Current LEA decoding is a bunch of special cases, properly decode the
instruction, with exception of full SIB and RIP-relative modes.

Hi,
Since I had to look at instruction decoding for the stack swizzle thing, I
ended up with a few more changes to the objtool x86 decoder.
These patches are lightly tested (they build defconfig and allmodconfig using
GCC10), but older versions have seen some robot exposure and other compilers.
Since we can now have multiple stack-ops per instruction, we don't
need to special case LEAVE and can simply emit the composite
operations.

When there's a SIB byte, the register otherwise denoted by r/m will
then be denoted by SIB.base REX.b will now extend this. SIB.index == SP
is magic and notes an index value zero.
This means that there's a bunch of alternative (longer) encodings for
the same thing. Eg. 'ModRM.mod != 3, ModRM.r/m =

Since the CFI_reg number now matches the instruction encoding order do
away with the op_to_cfi_reg[] and use direct assignment.

In GSI v1.0 the register GSI_HW_PARAM_2_OFFSET has different layout
so the number of channels and events per EE are, of course, laid out
in 8 bits each (0-7, 8-15 respectively).

The left shift of int 32 bit integer constant 1 is evaluated using 32 bit
arithmetic and then assigned to a signed 64 bit integer. In the case where
l2nb is 32 or more this can lead to an overflow. Avoid this by shifting
