In order to support short clock counters, provide an ABI extension.
As a whole:
u64 time, delta, cyc = read_cycle_counter();
+ if (cap_user_time_short)

delta = mul_u64_u32_shr(cyc, time_mult,
This patch set is rebased for Peter's patch set to support
cap_user_time/cap_user_time_short ABI for Arm64, and export Arm arch
timer counter related parameters from kernel to Perf tool.
In this version, there have two changes comparing to Peter's original
patch set [1]:
The first change is for

In order to support perf_event_mmap_page::cap_time features, an

As reported by Leo; the existing implementation is broken when the
clock and counter don't intersect at 0.
Use the sched_clock's struct clock_read_data information to correctly
implement cap_user_time and cap_user_time_zero.
Note that the ARM64 counter is architecturally

When sched_clock is running on anything other than arch_timer, don't

syzbot is reporting general protection fault in bitfill_aligned() [1]
caused by integer underflow in bit_clear_margins(). The cause of this
problem is when and how do_vc_resize() updates vc->vc_{cols,rows}.
If vc_do_resize() fails (e.g. kzalloc() fails) when var.xres or var.yres

when get_unused_fd_flags gets failure, userfaultfd_ctx_cachep will
be freed by userfaultfd_fops's release function which is the
userfaultfd_release. So we could return directly after fput().

Eek, no. MSR_IA32_MISC_ENABLE_XD_DISABLE needs to be cleared very early
