vfs: remove LOOKUP_NO_AUTOMOUNT flag
That flag no longer makes sense, since we don't look up automount points
as eagerly any more. Additionally, it turns out that the NO_AUTOMOUNT
handling was buggy to begin with: it would avoid automounting even for
cases where we really *needed* to do the automount handling, and could
return ENOENT for autofs entries that hadn't been instantiated yet.
With our new non-eager automount semantics, one discussion has been
about adding a AT_AUTOMOUNT flag to vfs_fstatat (and thus the
newfstatat() and fstatat64() system calls), but it's probably not worth
it: you can always force at least directory automounting by simply
adding the final '/' to the filename, which works for *all* of the stat
family system calls, old and new.
So AT_NO_AUTOMOUNT (and thus LOOKUP_NO_AUTOMOUNT) really were just a
result of our bad default behavior.

Currently the the internal oscillator is powered down when entering BIAS_OFF

vfs pathname lookup: Add LOOKUP_AUTOMOUNT flag
Since we've now turned around and made LOOKUP_FOLLOW *not* force an
automount, we want to add the ability to force an automount event on
lookup even if we don't happen to have one of the other flags that force
it implicitly (LOOKUP_OPEN, LOOKUP_DIRECTORY, LOOKUP_PARENT..)
Most cases will never want to use this, since you'd normally want to
delay automounting as long as possible, which usually implies
LOOKUP_OPEN (when we open a file or directory, we really cannot avoid
the automount any more).
But Trond argued sufficiently forcefully that at a minimum bind mounting
a file and quotactl will want to force the automount lookup. Some other
cases (like nfs_follow_remote_path()) could use it too, although
LOOKUP_DIRECTORY would work there as well.
This commit just adds the flag and logic, no users yet, though. It also
doesn't actually touch the LOOKUP_NO_AUTOMOUNT flag that is related, and
was made irrelevant by the same change that made us not follow on
LOOKUP_FOLLOW.

PM / Clocks: Do not acquire a mutex under a spinlock
Commit b7ab83e (PM: Use spinlock instead of mutex in clock
management functions) introduced a regression causing clocks_mutex
to be acquired under a spinlock. This happens because
pm_clk_suspend() and pm_clk_resume() call pm_clk_acquire() under
pcd->lock, but pm_clk_acquire() executes clk_get() which causes
clocks_mutex to be acquired. Similarly, __pm_clk_remove(),
executed under pcd->lock, calls clk_put(), which also causes
clocks_mutex to be acquired.
To fix those problems make pm_clk_add() call pm_clk_acquire(), so
that pm_clk_suspend() and pm_clk_resume() don't have to do that.
Change pm_clk_remove() and pm_clk_destroy() to separate
modifications of the pcd->clock_list list from the actual removal of
PM clock entry objects done by __pm_clk_remove().

The spec->autocfg.line_out_pins[] may contain the same pins as hp_pins[]

This patch fixes this by taking into account the actual buildid size as

perf tool: Fix endianness handling of u32 data in samples
Currently, analyzing PPC data files on x86 the cpu field is always 0 and
the tid and pid are backwards. For example, analyzing a PPC file on PPC
the pid/tid fields show:
rsyslogd 1210/1212
and analyzing the same PPC file using an x86 perf binary shows:
rsyslogd 1212/1210
The problem is that the swap_op method for samples is
perf_event__all64_swap which assumes all elements in the sample_data
struct are u64s. cpu, tid and pid are u32s and need to be handled
individually. Given that the swap is done before the sample is parsed,
the simplest solution is to undo the 64-bit swap of those elements when
the sample is parsed and do the proper swap.
The RAW data field is generic and perf cannot have programmatic knowledge
of how to treat that data. Instead a warning is given to the user.
Thanks to Anton Blanchard for providing a data file for a mult-CPU
PPC system so I could verify the fix for the CPU fields.
v3 -> v4:
- fixed use of WARN_ONCE
v2 -> v3:
- used WARN_ONCE for message regarding raw data
- removed struct wrapper around union
- fixed whitespace issues
v1 -> v2:
- added a union for undoing the byte-swap on u64 and redoing swap on
u32's to address compiler errors (see git commit
65014ab3)

perf sort: Fix symbol sort output by separating unresolved samples by type
I took a profile that suggested 60% of total CPU time was in the
hypervisor:
...
60.20% [H] 0x33d43c
4.43% [k] ._spin_lock_irqsave
1.07% [k] ._spin_lock
Using perf stat to get the user/kernel/hypervisor breakdown contradicted
this.
The problem is we merge all unresolved samples into the one unknown
bucket. If add a comparison by sample type to sort__sym_cmp we get the
real picture:
...
57.11% [.] 0x80fbf63c
4.43% [k] ._spin_lock_irqsave
1.07% [k] ._spin_lock
0.65% [H] 0x33d43c
So it was almost all userspace, not hypervisor as the initial profile
suggested.
I found another issue while adding this. Symbol sorting sometimes shows
multiple entries for the unknown bucket:
...
16.65% [.] 0x6cd3a8
7.25% [.] 0x422460
5.37% [.] yylex
4.79% [.] malloc
4.78% [.] _int_malloc
4.03% [.] _int_free
3.95% [.] hash_source_code_string
2.82% [.] 0x532908
2.64% [.] 0x36b538
0.94% [H] 0x8000000000e132a4
0.82% [H] 0x800000000000e8b0
This happens because we aren't consistent with our sorting. On
one hand we check to see if both symbols match and for two unresolved
samples sym is NULL so we match:
if (left->ms.sym == right->ms.sym)
return 0;
On the other hand we use sample IP for unresolved samples when
comparing against a symbol:
ip_l = left->ms.sym ? left->ms.sym->start : left->ip;
ip_r = right->ms.sym ? right->ms.sym->start : right->ip;
This means unresolved samples end up spread across the rbtree and we
can't merge them all.
If we use cmp_null all unresolved samples will end up in the one bucket
and the output makes more sense:
...
39.12% [.] 0x36b538
5.37% [.] yylex
4.79% [.] malloc
4.78% [.] _int_malloc
4.03% [.] _int_free
3.95% [.] hash_source_code_string
2.26% [H] 0x800000000000e8b0
