be1247782e staging: qlge/qlge_main.c: use generic power management
Drivers should not use legacy power management as they have to manage power
states and related operations, for the device, themselves. This driver was
handling them with the help of PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(), etc.

With generic PM, all essentials will be handled by the PCI core. Driver
needs to do only device-specific operations.

The driver was also using pci_enable_wake(...,..., 0) to disable wake. Use
device_wakeup_disable() instead.

Compile-tested only.

9dce29e65b ktest.pl: Have config-bisect save each config used in the bisect
When performing a automatic config bisect via ktest.pl, it is very useful to
have a copy of each of the bisects used. This way, if a bisect were to go
wrong, it is possible to retrace the steps and continue at the location
before the error was made.

The ktest.pl will make a copy of the good and bad configs, labeled as such,
as well as a number attached to it that represents the iteration of the
bisect. These files are saved in the ktest temp directory where it currently
stores the good and bad config files.

44c413d9a5 tty/vt: Do not warn when huge selection requested
The tty TIOCL_SETSEL ioctl allocates a memory buffer big enough for text
selection area. The maximum allowed console size is
VC_RESIZE_MAXCOL * VC_RESIZE_MAXROW == 32767*32767 == ~1GB and typical
MAX_ORDER is set to allow allocations lot less than than (circa 16MB).

So it is quite possible to trigger huge allocation (and syzkaller just
did that) which is going to fail (which is fine) with a backtrace in
mm/page_alloc.c at WARN_ON_ONCE(!(gfp_mask & __GFP_NOWARN)) and
this may trigger panic (if panic_on_warn is enabled) and
leak kernel addresses to dmesg.

This passes __GFP_NOWARN to kmalloc_array to avoid unnecessary user-
triggered WARN_ON. Note that the error is not ignored and
the warning is still printed.

40c45904f8 x86/ptrace: Fix 32-bit PTRACE_SETREGS vs fsbase and gsbase
Debuggers expect that doing PTRACE_GETREGS, then poking at a tracee
and maybe letting it run for a while, then doing PTRACE_SETREGS will
put the tracee back where it was.  In the specific case of a 32-bit
tracer and tracee, the PTRACE_GETREGS/SETREGS data structure doesn't
have fs_base or gs_base fields, so FSBASE and GSBASE fields are
never stored anywhere.  Everything used to still work because
nonzero FS or GS would result full reloads of the segment registers
when the tracee resumes, and the bases associated with FS==0 or
GS==0 are irrelevant to 32-bit code.

Adding FSGSBASE support broke this: when FSGSBASE is enabled, FSBASE
and GSBASE are now restored independently of FS and GS for all tasks
when context-switched in.  This means that, if a 32-bit tracer
restores a previous state using PTRACE_SETREGS but the tracee's
pre-restore and post-restore bases don't match, then the tracee is
resumed with the wrong base.

Fix it by explicitly loading the base when a 32-bit tracer pokes FS
or GS on a 64-bit kernel.

Also add a test case.

b865c5b322 misc: cxl: hcalls: Demote half-assed kerneldoc attempt
Function headers will need a lot of work before they reach the
standards expected of kerneldoc.  Demote them down to basic
comments/headers, for now at least.
