Commit 54ff4a1d1732 ("MIPS: Alchemy: pata_platform for DB1200")
from year 2014 converted the only user of au1xxx-ide IDE host
driver (MIPS Alchemy DB1200 platform) to use pata_platform
libata host driver instead. This patch removes dead au1xxx-ide
driver code.

Perf gets dso details from two different sources. 1st, from builid
headers in perf.data and 2nd from MMAP2 samples. Dso from buildid
header does not have dso_id detail. And dso from MMAP2 samples does
not have buildid information. If detail of the same dso is present
at both the places, filename is common.
Previously, __dsos__findnew_link_by_longname_id() used to compare only
long or short names, but Commit 0e3149f86b99 ("perf dso: Move dso_id
from 'struct map' to 'struct dso'") also added a dso_id comparison.
Because of that, now perf is creating two different dso objects of the
same file, one from buildid header (with dso_id but without buildid)
and second from MMAP2 sample (with buildid but without dso_id).
This is causing issues with archive, buildid-list etc subcommands. Fix
this by comparing dso_id only when it's present. And incase dso is
present in 'dsos' list without dso_id, inject dso_id detail as well.
Before:
$ sudo ./perf buildid-list -H
0000000000000000000000000000000000000000 /usr/bin/ls
0000000000000000000000000000000000000000 /usr/lib64/ld-2.30.so
0000000000000000000000000000000000000000 /usr/lib64/libc-2.30.so
$ ./perf archive
perf archive: no build-ids found
After:
$ ./perf buildid-list -H
b6b1291d0cead046ed0fa5734037fa87a579adee /usr/bin/ls
641f0c90cfa15779352f12c0ec3c7a2b2b6f41e8 /usr/lib64/ld-2.30.so
675ace3ca07a0b863df01f461a7b0984c65c8b37 /usr/lib64/libc-2.30.so
$ ./perf archive
Now please run:
$ tar xvf perf.data.tar.bz2 -C ~/.debug
wherever you need to run 'perf report' on.
Committer notes:
Renamed is_empty_dso_id() to dso_id__empty() and inject_dso_id() to
dso__inject_id() to keep namespacing consistent.
Fixes: 0e3149f86b99 ("perf dso: Move dso_id from 'struct map' to 'struct dso'")

The enum containing the *_PARTITION symbolic names is only relevant
for the partition parser. More specifically most values are MSDOS
partition table system indicators and thus should go straight into
msdos.c. One value is only used by the sun partition parser, and the
sun and sgi partition parsers use the same value as the x86 Linux
RAID indicator to also indicate RAID autodetection. Duplicate them
in sun.c and sgi.c given that the different partition types use
entirely different values otherwise.

regardless of whether an external regulator is taking care of the power

Tegra host supports HW busy detection and timeouts based on the
count programmed in SDHCI_TIMEOUT_CONTROL register and max busy
timeout it supports is 11s in finite busy wait mode.
Some operations like SLEEP_AWAKE, ERASE and flush cache through
SWITCH commands take longer than 11s and Tegra host supports
infinite HW busy wait mode where HW waits forever till the card
is busy without HW timeout.
This patch implements Tegra specific set_timeout sdhci_ops to allow
switching between finite and infinite HW busy detection wait modes
based on the device command expected operation time.

When SDHC gets reset (E.g. in runtime suspend path), CQE also gets
reset and goes to disable state. But s/w state still points it as CQE
is in enabled state. Since s/w and h/w states goes out of sync,
it results in s/w request timeout for subsequent CQE requests.
To synchronize CQE s/w and h/w state during SDHC reset,
explicitly deactivate CQE just before SDHC reset.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

Add creating event aliases to the pmu-events test.
So currently we verify that the generated pmu-events.c is as expected for
some test events. Now test that we generate aliases as expected for those
events during normal operation.
For that, we cycle through each HW PMU in the system, and use the test
events to create aliases, and verify those against known, expected values.
For core PMUs, we should create an alias for every event in
test_cpu_events[].
However, for uncore PMUs, they need to be matched by the pmu_event.pmu
member, so use test_uncore_events[]; so check the match beforehand with
pmu_uncore_alias_match().
A sample run is as follows for my x86 machine:
john@linux-3c19:~/linux> tools/perf/perf test -vv 10

The perf pmu-events test will want to use pmu_uncore_alias_match(), so
make it public.

The initial test will verify that the test tables in generated pmu-events.c
match against known, expected values.
For known events added in pmu-events/arch/test, we need to add an entry
in test_cpu_aliases_events[] or test_uncore_events[].
A sample run is as follows for x86:
john@linux-3c19:~/linux> tools/perf/perf test -vv 10
10: PMU event aliases :
--- start ---
test child forked, pid 5316
testing event table bp_l1_btb_correct: pass
testing event table bp_l2_btb_correct: pass
testing event table segment_reg_loads.any: pass
testing event table dispatch_blocked.any: pass
testing event table eist_trans: pass
testing event table uncore_hisi_ddrc.flux_wcmd: pass
testing event table unc_cbo_xsnp_response.miss_eviction: pass
test child finished with 0
---- end ----
PMU event aliases: Ok

Create pmu_add_cpu_aliases_map() from pmu_add_cpu_aliases(), so the caller
can pass the map; the pmu-events test would use this since there would
be no CPUID matching to a mapfile there.
