In the case of timeout waiting for data ready, the retry variable is -1.
This also fixes a bug: current code returns -ETIMEDOUT if latest retry success
( which means retry is 0 when exiting the while loop ).

According to the PCIe 3.0 spec, PCI_EXP_LNKCAP2_SLS_2_5GB is
1st bit of PCI_EXP_LNKCAP2 register, not 0th bit. So, the bit
definition of supported link speed vector should be fixed.

flush_tasklet is a struct, not a pointer in percpu var.
so use this_cpu_ptr to get the member pointer.

this_cpu_ptr/this_cpu_read is faster than per_cpu_ptr(p, smp_processor_id())
and can reduce memory accesses.
The latter helper needs to find the offset for current cpu,
and needs more assembler instructions which objdump shows in following.

The series contains updates to add in the NIC Rx and Tx checksumming support
for encapsulated packets.
The sk_buff needs to somehow have information of the inner packet, and adding
three fields for the inner mac, network and transport headers was the prefered
approach.

This version stores the user-input value in a separate location from
the jiffies values used by the scheduler, to prevent a race condition.

The --print-line option of perf annotate command shows summary for

If --asm-raw option was given, objdump output will contain hex numbers
of the instruction before the symbolic name. However current parser
code doesn't handle it properly. Fix it.

The perf annotate browser on TUI can identify a jump target for a
selected instruction. It assumes that the jump target is within the
function but it's not the case of PLT symbols which have offset out of
the function as a target. Since it caused a segmentation fault, do
