Running `perf test` as an i386 executable yielded a number of
failures, some of which are addressed here.
The first 2 are straightforward use strtoull issues when parsing a
64-bit quantity in 32-bit land.
The 3rd patch just avoids a fail when `perf probe` isn't compiled in
(in my case as LIBELF wasn't present).
The 4th and 5th cases fix the breakpoint length, on i386 so the
sizeof(long) used matches the kernel's sizeof(long). On aarch64 the
value is change to 4 instead of sizeof(long), ie 8, as future kernels
may make 8 an invalid argument.
The final change addresses i386 watchpoint support not supporting
8-byte values.
Ian Rogers (6):
perf pmus: Fix name comparisons on 32-bit systems
perf time-utils: Fix 32-bit nsec parsing
perf test: Skip uprobe test if probe command isn't present
perf parse-events: Add default_breakpoint_len helper
perf parse-events: Vary default_breakpoint_len on i386 and arm64
perf test: Make watchpoint data 32-bits on i386

The default breakpoint length is "sizeof(long)" however this is
incorrect on platforms like Aarch64 where sizeof(long) is 8 but the
breakpoint length is 4. Add a helper function that can be used to
determine the correct breakpoint length, in this change it just
returns the existing default sizeof(long) value.
Use the helper in the bp_account test so that, when modifying the
event from a watchpoint to a breakpoint, the breakpoint length is
appropriate for the architecture and not just sizeof(long).
