The current PS3 gelic wireless driver has support for wireless
extensions. The original PS3 gelic wireless driver exposed a
dedicated API for a dedicated wpa_supplicant driver. This old
API could be enabled with CONFIG_GELIC_WIRELESS_OLD_PSK_INTERFACE,
however, as this is not being used by any distros, and it is being
removed from the driver and from wpa_supplicant.

In hda_codec.c, it has define
"[HDA_PCM_TYPE_HDMI] = { 3, 7, 8, 9, -1 },",
it support up to device 9 for HDMI.
But in hda_intel.c, it only define AZX_MAX_PCMS as 8.
So if it have 4 hdmi codecs, when run azx_attach_pcm_stream(),
it will show error "Invalid PCM device number 8", and "... number 9",
and return "-EINVAL".
We should change the AZX_MAX_PCMS to 10.

Now we have either DAPM, or other ways to control these bits,
so there is no need to enable them by default.

Disable ADCL and ADCR
Disable ARXL2 and ARXR2 analog PGA (playback)
Disable APLL by default

I'm not sure about rcu stuff near kmem cache destruction:
* checks for non-empty hashes look bogus, they're done _before_
rcu_berrier()
* unregistering netns ops is done before kmem_cache destoy
(as it should), and unregistering involves rcu barriers by itself
So it looks nothing should be done.

We have to properly decrease bi_size in order to merge_bvec_fn return
right result. Otherwise this result in false merge rejects for two
absolutely valid bio_vecs. This may cause significant performance
penalty for example fs_block_size == 1k and block device is raid0 with
small chunk_size = 8k. Then it is impossible to merge 7-th fs-block in
to bio which already has 6 fs-blocks.

When running perf across all cpus with backtracing (-a -g), sometimes we
get samples without associated backtraces:
23.44% init [kernel] [k] restore
11.46% init eeba0c [k] 0x00000000eeba0c
6.77% swapper [kernel] [k] .perf_ctx_adjust_freq
5.73% init [kernel] [k] .__trace_hcall_entry
4.69% perf libc-2.9.so [.] 0x0000000006bb8c
|
|--11.11%-- 0xfffa941bbbc
It turns out the backtrace code has a check for the idle task and the IP
sampling does not. This creates problems when profiling an interrupt
heavy workload (in my case 10Gbit ethernet) since we get no backtraces
for interrupts received while idle (ie most of the workload).
Right now x86 and sh check that current is not NULL, which should never
happen so remove that too.
Idle task's exclusion must be performed from the core code, on top
of perf_event_attr:exclude_idle.

On a given architecture, when hardware breakpoint registration fails
due to un-supported access type (read/write/execute), we lose the bp
slot since register_perf_hw_breakpoint() does not release the bp slot
on failure.
Hence, any subsequent hardware breakpoint registration starts failing
with 'no space left on device' error.
This patch introduces error handling in register_perf_hw_breakpoint()
function and releases bp slot on error.

The VBR value needs to be initialized in order for any of the bios
trapping to work, and as we don't do that until slightly later in the
boot process, this has no real chance of working.
The only reason for using this in the past was due to the fact that early
serial initialization wasn't possible, but now that early sh-sci is
supported by everyone, there's no longer any reason to support the
sh_bios hacks in the first place. Given that, we just kill off the
references completely.

The MIPS processor is limited to 64 external interrupt sources. Using a
greater number without IRQ sharing requires reading platform-specific
registers. On such platforms, reading the IntCtl register to determine
which interrupt corresponds to a timer interrupt will not work.
On MIPSR2 systems there is a solution - the TI bit in the Cause register,
specifically indicates that a timer interrupt has occured. This patch uses
that bit to detect interrupts for MIPSR2 processors, which may be expected
to work regardless of how the timer interrupt may be routed in the hardware.

POSIX requires $((<expression>)) arithmetic in sh only to have long
arithmetic so on 32-bit sh binaries might do only 32-bit arithmetic but
the arithmetic done in arch/mips/boot/compressed/Makefile needs 64-bit.
I play with the AR7 platform, so VMLINUX_LOAD_ADDRESS is
0xffffffff94100000, and for an example 4MiB kernel
VMLINUZ_LOAD_ADDRESS is made out to be:
----
alex@berk:~$ bash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))'
ffffffff94500000
alex@berk:~$ dash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))'
80000000003fffff
----
The former is obviously correct whilst the later breaks things royally.
Fortunately working with only the lower 32bit's works for both bash and
dash:
----
$ bash -c 'printf "%x\n" $((0x94100000 + 0x400000))'
94500000
$ dash -c 'printf "%x\n" $((0x94100000 + 0x400000))'
94500000
----
So, we can split the original 64bit string to two parts, and only
calculate the low 32bit part, which is big enough (1GiB kernel sizes
anyone?) for a normal Linux kernel image file, now, we calculate the
VMLINUZ_LOAD_ADDRESS like this:
1. if present, append top 32bit of VMLINUX_LOAD_ADDRESS" as a prefix
2. get the sum of the low 32bit of VMLINUX_LOAD_ADDRESS + VMLINUX_SIZE
This patch fixes vmlinuz kernel builds on systems where only a
32bit-only math shell is available.
Patch Changelog:
Version 2
- simplified method by using 'expr' for 'substr' and making it work
with dash once again
Version 1
- Revert the removals of '-n "$(VMLINUX_SIZE)"' to avoid the error
of "make clean"
- Consider more cases of the VMLINUX_LOAD_ADDRESS
Version 0
- initial release
