The MPX code can only work on the current task. You can not,
for instance, enable MPX management in another process or
thread. You can also not handle a fault for another process or
thread.
Despite this, we pass a task_struct around prolifically. This
patch removes all of the task struct passing for code paths
where the code can not deal with another task (which turns out
to be all of them).
This has no functional changes. It's just a cleanup.

The MPX registers (bndcsr/bndcfgu/bndstatus) are not directly
accessible via normal instructions. They essentially act as
if they were floating point registers and are saved/restored
along with those registers.
There are two main paths in the MPX code where we care about
the contents of these registers:
1. #BR (bounds) faults
2. the prctl() code where we are setting MPX up
Both of those paths _might_ be called without the FPU having
been used. That means that 'tsk->thread.fpu.state' might
never be allocated.
Also, fpu_save_init() is not preempt-safe. It was a bug to
call it without disabling preemption. The new
get_xsave_addr() calls unlazy_fpu() instead and properly
disables preemption.

The MPX code appears is calling a low-level FPU function
(copy_fpregs_to_fpstate()). This function is not able to
be called in all contexts, although it is safe to call
directly in some cases.
Although probably correct, the current code is ugly and
potentially error-prone. So, add a wrapper that calls
the (slightly) higher-level fpu__save() (which is preempt-
safe) and also ensures that we even *have* an FPU context
(in the case that this was called when in lazy FPU mode).
Ingo had this to say about the details about when we need
preemption disabled:
> it's indeed generally unsafe to access/copy FPU registers with preemption enabled,
> for two reasons:
>
> - on older systems that use FSAVE the instruction destroys FPU register
> contents, which has to be handled carefully
>
> - even on newer systems if we copy to FPU registers (which this code doesn't)
> then we don't want a context switch to occur in the middle of it, because a
> context switch will write to the fpstate, potentially overwriting our new data
> with old FPU state.
>
> But it's safe to access FPU registers with preemption enabled in a couple of
> special cases:
>
> - potentially destructively saving FPU registers: the signal handling code does
> this in copy_fpstate_to_sigframe(), because it can rely on the signal restore
> side to restore the original FPU state.
>
> - reading FPU registers on modern systems: we don't do this anywhere at the
> moment, mostly to keep symmetry with older systems where FSAVE is
> destructive.
>
> - initializing FPU registers on modern systems: fpu__clear() does this. Here
> it's safe because we don't copy from the fpstate.
>
> - directly writing FPU registers from user-space memory (!). We do this in
> fpu__restore_sig(), and it's safe because neither context switches nor
> irq-handler FPU use can corrupt the source context of the copy (which is
> user-space memory).
>
> Note that the MPX code's current use of copy_fpregs_to_fpstate() was safe I think,

get_xsave_addr() assumes that if an xsave bit is present in the
hardware (pcntxt_mask) that it is present in a given xsave
buffer. Due to an bug in the xsave code on all of the systems
that have MPX (and thus all the users of this code), that has
been a true assumption.
But, the bug is getting fixed, so our assumption is not going
to hold any more.
It's quite possible (and normal) for an enabled state to be
present on 'pcntxt_mask', but *not* in 'xstate_bv'. We need
to consult 'xstate_bv'.

rearranged the PTE bits into fixed positions in preparation for the XPA

into consideration for the RI/XI bits leading to boot failures. We fix

Passive DP->DVI/HDMI dongles on DP++ ports show up to the system as HDMI
devices, as they do not have a sink device in them to respond to any AUX
traffic. When probing these dongles over the DDC, sometimes they will
NAK the first attempt even though the transaction is valid and they
support the DDC protocol. The retry loop inside of
drm_do_probe_ddc_edid() would normally catch this case and try the
transaction again, resulting in success.
That, however, was thwarted by the fix for [1]:
commit 9292f37e1f5c79400254dca46f83313488093825

drm: give up on edid retries when i2c bus is not responding
This added code to exit immediately if the return code from the
i2c_transfer function was -ENXIO in order to reduce the amount of time
spent in waiting for unresponsive or disconnected devices. That was
possible because the underlying i2c bit banging algorithm had retries of
its own (which, of course, were part of the reason for the bug the
commit fixes).
Since its introduction in
commit f899fc64cda8569d0529452aafc0da31c042df2e
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date: Tue Jul 20 15:44:45 2010 -0700
drm/i915: use GMBUS to manage i2c links
we've been flipping back and forth enabling the GMBUS transfers, but
we've settled since then. The GMBUS implementation does not do any
retries, however, bailing out of the drm_do_probe_ddc_edid() retry loop
on first encounter of -ENXIO. This, combined with Eugeni's commit, broke
the retry on -ENXIO.
Retry GMBUS once on -ENXIO on first message to mitigate the issues with
passive adapters.
This patch is based on the work, and commit message, by Todd Previte
<tprevite@gmail.com>.

v2: Don't retry if using bit banging.

iser connection termination process happens in 2 stages:
- isert_wait_conn:
- resumes rdma disconnect
- wait for session commands
- wait for flush completions (post a marked wr to signal we are done)
- wait for logout completion
- queue work for connection cleanup (depends on disconnected/timewait
events)
- isert_free_conn
- last reference put on the connection
In case we are terminating during IOs, we might be posting send/recv
requests after we posted the last work request which might lead
to a use-after-free condition in isert_handle_wc.
After we posted the last wr in isert_wait_conn we are guaranteed that
no successful completions will follow (meaning no new work request posts
may happen) but other flush errors might still come. So before we
put the last reference on the connection, we repeat the process of
posting a marked work request (isert_wait4flush) in order to make sure all
pending completions were flushed.

When receiving a new iser connect request we serialize
the pending requests by adding the newly created iser connection
to the np accept list and let the login thread process the connect
request one by one (np_accept_wait).
In case we received a disconnect request before the iser_conn
has begun processing (still linked in np_accept_list) we should
detach it from the list and clean it up and not have the login
thread process a stale connection. We do it only when the connection
state is not already terminating (initiator driven disconnect) as
this might lead us to access np_accept_mutex after the np was released
in live shutdown scenarios.

Since commit "2426bd456a6 target: Report correct response ..."
we might get a command with data_size that does not fit to
the number of allocated data sg elements. Given that we rely on
cmd t_data_nents which might be different than the data_size,
we sometimes receive local length error completion. The correct
approach would be to take the command data_size into account when
constructing the ib sg_list.

__NR_syscall_compat_max
Brian Gerst noticed that I did a weird rename in the following commit:
b2502b418e63 ("x86/asm/entry: Untangle 'system_call' into two entry points: entry_SYSCALL_64 and entry_INT80_32")
which renamed __NR_ia32_syscall_max to __NR_entry_INT80_compat_max.
Now the original name was a misnomer, but the new one is a misnomer as well,
as all the 32-bit compat syscall entry points (sysenter, syscall) share the
system call table, not just the INT80 based one.
Rename it to __NR_syscall_compat_max.

I broke this recently when I changed pt_regs->r8..r11 clearing
logic in INT 80 code path.
There is a branch from SYSENTER/SYSCALL code to INT 80 code:
if we fail to retrieve arg6, we return EFAULT. Before this
patch, in this case we don't clear pt_regs->r8..r11.
This patch fixes this. The resulting code is smaller and
simpler.
While at it, remove incorrect comment about syscall dispatching

comment was meant to be "TODO: make this rip-relative", and

Commit 70008aa50e92 ("skbuff: convert to skb_orphan_frags") replaced
open coded tests of SKBTX_DEV_ZEROCOPY and skb_copy_ubufs with calls
to helper function skb_orphan_frags. Apply that to the last remaining
open coded site.

The RGMII block is currently only powered on when using RGMII or
RGMII_NO_ID, which is not correct when using the GENET interface in MII
or Reverse MII modes. We always need to power on the RGMII interface for
this block to properly work, regardless of the MII mode in which we
operate.

UDP encapsulation is broken on IPv6. This is because the logic to resubmit
the nexthdr is inverted, checking for a ret value > 0 instead of < 0. Also,
the resubmit label is in the wrong position since we already get the
nexthdr value when performing decapsulation. In addition the skb pull is no
longer necessary either.
This changes the return value check to look for < 0, using it for the
nexthdr on the next iteration, and moves the resubmit label to the proper
location.
With these changes the v6 code now matches what we do in the v4 ip input
code wrt resubmitting when decapsulating.

The memory pointed to by idev->stats.icmpv6msgdev,
idev->stats.icmpv6dev and idev->stats.ipv6 can each be used in an RCU
read context without taking a reference on idev. For example, through
IP6_*_STATS_* calls in ip6_rcv. These memory blocks are freed without
waiting for an RCU grace period to elapse. This could lead to the
memory being written to after it has been freed.
Fix this by using call_rcu to free the memory used for stats, as well
as idev after an RCU grace period has elapsed.

This has a different model than the 'thread' and 'map' struct lifetimes:
there is not a definitive "don't use this DSO anymore" event, i.e. we may
get many 'struct map' holding references to the '/usr/lib64/libc-2.20.so'
DSO but then at some point some DSO may have no references but we still
don't want to straight away release its resources, because "soon" we may
get a new 'struct map' that needs it and we want to reuse its symtab or
other resources.
So we need some way to garbage collect it when crossing some memory
usage threshold, which is left for anoter patch, for now it is
sufficient to release it when calling dsos__exit(), i.e. when deleting
the whole list as part of deleting the 'struct machine' containing it,
which will leave only referenced objects being used.

Calling the function 'machine__new_module' implies a new 'module' will
be allocated, when in fact what is returned is a 'struct map' instance,
that not necessarily will be instantiated, as if one already exists with
the given module name, it will be returned instead.
So be consistent with other "find and if not there, create" like
functions, like machine__findnew_thread, machine__findnew_dso, etc, and
rename it to machine__findnew_module_map(), that in turn will call
machine__findnew_module_dso().

Traceevent plugins need dynamic symbols exported from libtraceevent.a,
otherwise a dlopen error will occur during plugins loading.
This patch uses dynamic-list-file to export dynamic symbols which will
be used in plugins to perf executable.
The problem is covered up if feature-libpython is enabled, because
PYTHON_EMBED_LDOPTS contains '-Xlinker --export-dynamic' which adds all
symbols to the dynamic symbol table. So we should reproduce the problem
by setting NO_LIBPYTHON=1.

So, I'm told this problem exists in the world:
> Subject: Build error in -next due to 'efi: Add esrt support'
>
> Building ia64:defconfig ... failed
> --------------
> Error log:
>
> drivers/firmware/efi/esrt.c:28:31: fatal error: asm/early_ioremap.h: No such file or directory
>
I'm not really sure how it's okay that we have things in asm-generic on
some platforms but not others - is having it the same everywhere not the
whole point of asm-generic?
That said, ia64 doesn't have early_ioremap.h . So instead, since it's
difficult to imagine new IA64 machines with UEFI 2.5, just don't build
this code there.
To me this looks like a workaround - doing something like:
generic-y += early_ioremap.h
in arch/ia64/include/asm/Kbuild would appear to be more correct, but
ia64 has its own early_memremap() decl in arch/ia64/include/asm/io.h ,
and it's a macro. So adding the above /and/ requiring that asm/io.h be
included /after/ asm/early_ioremap.h in all cases would fix it, but
that's pretty ugly as well. Since I'm not going to spend the rest of my
life rectifying ia64 headers vs "generic" headers that aren't generic,
it's much simpler to just not build there.
Note that I've only actually tried to build this patch on x86_64, but
esrt.o still gets built there, and that would seem to demonstrate that
the conditional building is working correctly at all the places the code
built before. I no longer have any ia64 machines handy to test that the
exclusion actually works there.
