When the "--cpu-set" option limits turbostat to run on
a higher numbered HT sibling, it exits upon dividing by zero.
This is because the HT support handles higher numbered siblings
at the same time as lower numbered siblings. But when that lower
number sibling is dis-allowed, the higher numbered sibling is
never processed. The result is a time delta of 0, which results
in a divide by 0 for any of the "per-second" metrics.
Enhance the HT enumeration code to record all siblings (up to SMT4).
Consult this complete HT sibling list to determine when
to process an HT sibling, and when to skip it.

"turbostat --cpu-set 0" appears to hang if cpu0 has an HT sibling.
This is because the initialization code recognizes that it does not
have to open perf files for the HT sibling, but the HT support
in the collection code sees the HT sibling and tries to read
from an uninitialized file descriptor, 0 (standard input).
Access HT siblings only when they are in the allowed set.

Calvin reported an odd NMI watchdog lockup which claims that the CPU locked
up in user space. He provided a reproducer, which sets up a timerfd based
timer and then rearms it in a loop with an absolute expiry time of 1ns.
As the expiry time is in the past, the timer ends up as the first expiring
timer in the per CPU hrtimer base and the clockevent device is programmed
with the minimum delta value. If the machine is fast enough, this ends up
in a endless loop of programming the delta value to the minimum value
defined by the clock event device, before the timer interrupt can fire,
which starves the interrupt and consequently triggers the lockup detector
because the hrtimer callback of the lockup mechanism is never invoked.
As a first step to prevent this, avoid reprogramming the clock event device
when:
- a forced minimum delta event is pending
- the new expiry delta is less then or equal to the minimum delta
Thanks to Calvin for providing the reproducer and to Borislav for testing
and providing data from his Zen5 machine.
The problem is not limited to Zen5, but depending on the underlying
clock event device (e.g. TSC deadline timer on Intel) and the CPU speed
not necessarily observable.
This change serves only as the last resort and further changes will be made
to prevent this scenario earlier in the call chain as far as possible.
[ tglx: Updated to restore the old behaviour vs. !force and delta <= 0 and
fixed up the tick-broadcast handlers as pointed out by Borislav ]

Switch from raw pointers to ns_common::ns_id for both hashing

A preparatory commit first replaces all const void * namespace

Currently, if perf_l2_init() fails turbostat exits after issuing the
following error (which was encountered on AlderLake):
turbostat: perf_l2_init(cpu0, 0x0, 0xff24) REFS: Invalid argument
This occurs because perf_l2_init() calls err(). However, the code has been
written in such a manner that it is able to perform cleanup and continue.
Therefore, this issue can be addressed by changing the appropriate calls
to err() to warnx().
Additionally, correct the PMU type arguments passed to the warning strings
in the ecore and lcore blocks so the logs accurately reflect the failing
counter type.

====================
net: lan966x: fix page_pool error handling and error paths
This series fixes error handling around the lan966x page pool:
1/3 adds the missing IS_ERR check after page_pool_create(), preventing
a kernel oops when the error pointer flows into
xdp_rxq_info_reg_mem_model().
2/3 plugs page pool leaks in the lan966x_fdma_rx_alloc() and
lan966x_fdma_init() error paths, now reachable after 1/3.
3/3 fixes a use-after-free and page pool leak in the
lan966x_fdma_reload() restore path, where the hardware could
resume DMA into pages already returned to the page pool.

When lan966x_fdma_reload() fails to allocate new RX buffers, the restore
path restarts DMA using old descriptors whose pages were already freed
via lan966x_fdma_rx_free_pages(). Since page_pool_put_full_page() can
release pages back to the buddy allocator, the hardware may DMA into
memory now owned by other kernel subsystems.
Additionally, on the restore path, the newly created page pool (if
allocation partially succeeded) is overwritten without being destroyed,
leaking it.
Fix both issues by deferring the release of old pages until after the
new allocation succeeds. Save the old page array before the allocation
so old pages can be freed on the success path. On the failure path, the
old descriptors, pages and page pool are all still valid, making the
restore safe. Also ensure the restore path re-enables NAPI and wakes
the netdev, matching the success path.

lan966x_fdma_rx_alloc() creates a page pool but does not destroy it if
the subsequent fdma_alloc_coherent() call fails, leaking the pool.
Similarly, lan966x_fdma_init() frees the coherent DMA memory when
lan966x_fdma_tx_alloc() fails but does not destroy the page pool that
was successfully created by lan966x_fdma_rx_alloc(), leaking it.
Add the missing page_pool_destroy() calls in both error paths.
