Don't attempt to load PDPTRs if EFER.LME=1, i.e. if 64-bit mode is
enabled. A recent change to reload the PDTPRs when CR0.CD or CR0.NW is
toggled botched the EFER.LME handling and sends KVM down the PDTPR path
when is_paging() is true, i.e. when the guest toggles CD/NW in 64-bit
mode.

Info: Write valid nat_bits in checkpoint
[FIX]
Dumping testbus registers needs to sleep a bit intermittently as there are
too many of them. Skip them for those contexts where sleep is not allowed.
Meanwhile, if ufs_qcom_dump_dbg_regs() calls ufs_qcom_testbus_config() from
ufshcd_suspend/resume and/or clk gate/ungate context,
The scsi_block_reqs_cnt increased in ufshcd_hold() is supposed to be
decreased back in ufshcd_ungate_work() in a paired way. However, if
specific ufshcd_hold/release sequences are met, it is possible that
scsi_block_reqs_cnt is increased twice but only one ungate work is
queued. To make sure
Clock gating features can be turned on/off selectively which means its
state information is only important if it is enabled. This change makes
sure that we only look at state of clk-gating if it is enabled.

The BFD linker generates runtime relocations for z_input_len and
z_output_len, even though they are absolute symbols.
This is fixed for binutils-2.35 [1]. Work around this for earlier
versions by defining two variables input_len and output_len in addition
to the symbols, and use them via
gcc puts the main function into .text.startup when compiled with -Os (or

The BFD linker places this orphan section immediately
From: Ard Biesheuvel
In a previous patch, we have eliminated GOT entries from the decompressor
binary and added an assertion that the .got section is empty. This means
that the GOT fixup routines that exist in both the 32-bit and 64-bit
startup routines have become dead code, and can be removed.
The assembly code in head_{32,64}.S, while meant to be
position-independent, generates run-time relocations because it uses
instructions such as
lealgdt(%edx), %eax
which make the assembler and linker think that the code is using %edx as
an index into gdt, and hence gdt needs to be
Add a linker script check that there are no runtime relocations, and
remove the old one that tries to check via looking for specially-named
sections in the object files.
Drop the tests for -fPIE compiler option and -pie linker option, as they
are available in all supported gcc and binutils
From: Ard Biesheuvel
Eliminate all GOT entries in the decompressor binary, by forcing hidden
visibility for all symbol references, which informs the compiler that
such references will be resolved at link time without the need for
allocating GOT entries.
To ensure that no GOT entries will creep
The compressed kernel currently contains bogus runtime relocations in
the startup code in head_{32,64}.S, which are generated by the linker,
but must not actually be processed at runtime.
This generates warnings when linking with the BFD linker, and errors
with LLD, which defaults to erroring on

We are getting this soft lockup in fanotify_read.
The reason is that this code does not seem to scale to cases where there
are big bursts of events generated by fanotify_handle_event.
fanotify_read acquires group->notification_lock for each event.
fanotify_handle_event uses the lock to add one

If you use devm_ioremap_resource() you can remove the !res check

The vm_flags may be changed after call_mmap() because drivers may set some
flags for their own purpose. As a result, we failed to merge the adjacent
vma due to the different vm_flags as userspace can't pass in the same one.
