* refactor the save_vector_registers_x86() algorithm to depend directly on preempt_count(), and use local_bh_enable() and preempt_disable() directly, to mitigate glitchiness around irq_fpu_usable() and crypto_simd_usable();
* eliminate the WC_FPU_ALREADY_FLAG kludge.
* improve the error and warning messages, and add some additional checks and messages for unexpected states; add VRG_PR_ERR_X and VRG_PR_WARN_X for pr_*_once() semantics on regular builds, but unlimited messages when WOLFSSL_LINUXKM_VERBOSE_DEBUG.
linuxkm/linuxkm_wc_port.h and linuxkm/module_hooks.c:
* move the spinlock-based implementation of wc_LockMutex() from linuxkm_wc_port.h to module_hooks.c, due to numerous stuboorn direct external symbol references;
* extensively refactor the kernel header #include strategy, keeping many more superfluous headers out of __PIE__ objects, and fixing unavoidable static header functions with grafted __always_inline attributes;
* add version exceptions for RHEL 9.5.
linuxkm/Kbuild:
* on x86 with CONFIG_MITIGATION_{RETPOLINE,RETHUNK}, use inline rethunks rather than none;
* refactor check for "Error: section(s) missed by containerization." using `readelf --sections --syms`, for 100% coverage, more informative error output, and suppression of false positives on printk-related cruft;
configure.ac and linuxkm/lkcapi_sha_glue.c: use LINUXKM_LKCAPI_[DONT_]REGISTER_{SHA,HMAC}_ALL to represent --enable-linuxkm-lkcapi-register=[-]all-{sha,hmac}, which allows alg families (notably SHA1) to be masked out piecemeal;
linuxkm/lkcapi_rsa_glue.c: in linuxkm_test_pkcs1pad_driver(), mitigate unused args when LINUXKM_AKCIPHER_NO_SIGNVERIFY.
