Subject: [PATCH v3] eal/arm64: update CPU flags
From: "Wei Hu (Xavier)" <xavier.hu...@huawei.com>
SVE is the next-generation SIMD extension of the ARMv8-A AArch64
instruction set.
The related marco definition can be found in linux kernel:
arch/arm64/include/uapi/asm/hwcap.h
This patch updates cpu SVE flags on ARM64 platform, such as SVE, etc.
Suggested rewording:
ARM64 Linux kernel updated the CPU flags using the HWCAP scheme.
This patch incorporates those changes to the eal library.
Ok, I will update it in V4.

v2 -> v3:
1. Change commit log.
2. Add HWCAP2_FLAGM2 and HWCAP2_FRINT to
rte_cpu_feature_table[].
3. Add the flags for newly added items into enum rte_cpu_flag_t.
v1 -> v2:
Adds more sve-related definition to rte_cpu_feature_table,
sunch as SVE2, etc.

How about updating test_cpuflags() too to cover these new flags?
+1 . Wei, Please update the test_cpuflags() functions for new flags.
OK, I will update this test function in V4.
Thanks
Xavier
