gcc complains about the 'cols' variable being unused. This is
unavoidable, given the ncurses getmaxyx() macro-based API, which wants
to assign to a variable directly, even when we're not going to use it.

Some distros (e.g., Arch Linux) don't package the tinfo library
separately from ncurses, so don't unconditionally include it. Instead,
use pkg-config.
The $(STATIC) ugliness is to handle the reported build case from commit
6b533269fb ("tools/thermal: tmon: fix compilation errors when building
statically"), where a developer wants to be able to build with:
make LDFLAGS=-static
which requires an additional pkg-config flag.
Finally, support a lowest common denominator fallback (-lpanel
-lncurses) for build systems that don't have pkg-config entries for
ncurses.

The number of rows in the dialog vary according to the number of cooling
devices. However, some of the windowing computations were assuming a
fixed number of rows. This computation is OK when we have between 4 and
9 cooling devices (and they wrap to the next column), but with fewer
devices, we end up printing off the end of the window.
This unifies the row computation into a single function and uses that
throughout the TUI code. This also accounts for increasing the number of
rows when there are more than 9 total cooling devices.

someone might stick the following in their boot script:

ARM64 CPUidle driver requires the cpu_do_idle function so that it can
be used to enter the shallowest idle state, and it is declared in
asm/proc-fns.h.
The current ARM64 CPUidle driver does not include asm/proc-fns.h
explicitly and it has so far relied on implicit inclusion from other
header files.
Owing to some header dependencies reshuffling this currently triggers
build failures when CONFIG_ARM64_64K_PAGES=y:
drivers/cpuidle/cpuidle-arm64.c: In function "arm64_enter_idle_state"
drivers/cpuidle/cpuidle-arm64.c:42:3: error: implicit declaration of
function "cpu_do_idle" [-Werror=implicit-function-declaration]
cpu_do_idle();
^
This patch adds the explicit inclusion of the asm/proc-fns.h header file
in the arm64 asm/cpuidle.h header file, so that the build breakage is fixed
and the required header inclusion is added to the appropriate arch back-end
CPUidle header, already included by the CPUidle arm64 driver, where
CPUidle arch related function declarations belong.

The native (64-bit) sigval_t union contains sival_int (32-bit) and
sival_ptr (64-bit). When a compat application invokes a syscall that
takes a sigval_t value (as part of a larger structure, e.g.
compat_sys_mq_notify, compat_sys_timer_create), the compat_sigval_t
union is converted to the native sigval_t with sival_int overlapping
with either the least or the most significant half of sival_ptr,
depending on endianness. When the corresponding signal is delivered to a
compat application, on big endian the current (compat_uptr_t)sival_ptr
cast always returns 0 since sival_int corresponds to the top part of
sival_ptr. This patch fixes copy_siginfo_to_user32() so that sival_int
is copied to the compat_siginfo_t structure.

With commit 3690951fc6 (arm64: Use swiotlb late initialisation), the

platforms with 32-bit only devices that require bounce buffering via
swiotlb. This patch changes the swiotlb initialisation to an early 64MB
memblock allocation. In order to get the swiotlb buffer correctly
allocated (via memblock_virt_alloc_low_nopanic), this patch also defines
ARCH_LOW_ADDRESS_LIMIT to the maximum physical address capable of 32-bit

Patch 2f896d5866 ("arm64: use fixmap for text patching") changed

This is triggered by the use of virt_to_page() on a module address,
which ends to pointing to Nowhereland if you're lucky, or corrupt
your precious data if not.
This patch fixes the logic by mimicking what is done on arm:
- If we're patching a module and CONFIG_DEBUG_SET_MODULE_RONX is set,
use vmalloc_to_page().
- If we're patching the kernel and CONFIG_DEBUG_RODATA is set,
use virt_to_page().
- Otherwise, use the provided address, as we can write to it directly.

This patch increases the interleave factor for parallel AES modes
to 4x. This improves performance on Cortex-A57 by ~35%. This is
due to the 3-cycle latency of AES instructions on the A57's
relatively deep pipeline (compared to Cortex-A53 where the AES
instruction latency is only 2 cycles).
At the same time, disable inline expansion of the core AES functions,
as the performance benefit of this feature is negligible.

Caught during Trinity testing. The pte_modify does not allow
modification for PTE type bit. This cause the test to hang
the system. It is found that the PTE can't transit from an
inaccessible page (b00) to a valid page (b11) because the mask
does not allow it. This happens when a big block of mmaped
memory is set the PROT_NONE, then the a small piece is broken
off and set to PROT_WRITE | PROT_READ cause a huge page split.

The vdso implementation of clock_getres currently returns 0 (success)
whenever a null timespec is provided by the caller, regardless of the
clock id supplied.
This behavior is incorrect. It should fall back to syscall when an
unrecognized clock id is passed, even when the timespec argument is
null. This ensures that clock_getres always returns an error for
invalid clock ids.

The atom aux param interface only supports 4 bits for
the total write transfer size (header + payload). This
limits us to 12 bytes of payload rather than 16. Add a
check for this. Reads are not affected.

The recent build changes cause perf to not compile for sparc64 since the
arch/sparc64/Build file does not exist:
/home/dahern/kernels/linux.git/tools/build/Makefile.build:40: arch/sparc64/Build: No such file or directory
Fix by converting the sparc64 RAW_ARCH to sparc ARCH -- similar to what
is done for x86_64.

perf evlist: Refcount mmaps
We need to know how many fds are using a perf mmap via
PERF_EVENT_IOC_SET_OUTPUT, so that we can know when to ditch an mmap,
refcount it.
This commit added 'int refcnt' to struct perf_mmap and the addition makes the
event_copy element no longer 8-byte aligned.
Fix by adding __attribute__((aligned(8))) to the event_copy struct
member.

Commit f6edb53c49 converted the probe to
a CPU wide event first (pid == -1). For kernels that do not support
the PERF_FLAG_FD_CLOEXEC flag the probe fails with EINVAL. Since this
errno is not handled pid is not reset to 0 and the subsequent use of
pid = -1 as an argument brings in an additional failure path if
perf_event_paranoid > 0:
$ perf record -- sleep 1
perf_event_open(..., 0) failed unexpectedly with error 13 (Permission denied)
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.007 MB /tmp/perf.data (11 samples) ]
Also, ensure the fd of the confirmation check is closed and comment why
pid = -1 is used.
Needs to go to 3.18 stable tree as well.

Commit 5d425c1865 ("arm64: kernel: add support for cpu cache
information") adds cacheinfo support for ARM64. Since there's no
architectural way of detecting the cpus that share particular cache,
device tree can be used and the core cacheinfo already supports the
same.
This patch adds the L2 cache topology on Juno board, FVP/RTSM and
foundation models.

The man page for pthread_attr_set_affinity_np states that _GNU_SOURCE
must be defined before pthread.h is included in order to get the proper
function declaration. Define this in the Makefile.
Without this defined, the feature check fails on a Fedora system with
gcc5 and then the perf build later fails with conflicting prototypes for
the function.
