[ Upstream commit 2893cc8f ] Presently we check first if CPUID is enabled. If it is not already enabled, then we next call identify_cpu_without_cpuid() and clear X86_FEATURE_CPUID. Unfortunately, identify_cpu_without_cpuid() is the function where CPUID becomes _enabled_ on Cyrix 6x86/6x86L CPUs. Reverse the calling sequence so that CPUID is first enabled, and then check a second time to see if the feature has now been activated.

[ Upstream commit 03b099bd ] There are comments in processor-cyrix.h advising you to _not_ make calls using the deprecated macros in this style: setCx86_old(CX86_CCR4, getCx86_old(CX86_CCR4) | 0x80); This is because it expands the macro into a non-functioning calling sequence. The calling order must be: outb(CX86_CCR2, 0x22); inb(0x23); From the comments: * When using the old macros a line like * setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88); * gets expanded to: * do { * outb((CX86_CCR2), 0x22); * outb((({ * outb((CX86_CCR2), 0x22); * inb(0x23); * }) | 0x88), 0x23); * } while (0); The new macros fix this problem, so use them instead.

[ Upstream commit 32c00979 ] following commit: commit d58e468b ("flow_dissector: implements flow dissector BPF hook") added struct bpf_flow_keys which conflicts with the struct with same name in sockex2_kern.c and sockex3_kern.c similar to commit: commit 534e0e52 ("samples/bpf: fix a compilation failure") we tried the rename it "flow_keys" but it also conflicted with struct having same name in include/net/flow_dissector.h. Hence renaming the struct to "flow_key_record". Also, this commit doesn't fix the compilation error completely because the similar struct is present in sockex3_kern.c. Hence renaming it in both files sockex3_user.c and sockex3_kern.c Signed-off-by:

[ Upstream commit a5e9f557 ] In commit 9f480fae ("crypto: chacha20 - Fix keystream alignment for chacha20_block()"), I had missed that chacha20_block() can be called directly on the buffer passed to get_random_bytes(), which can have any alignment. So, while my commit didn't break anything, it didn't fully solve the alignment problems. Revert my solution and just update chacha20_block() to use put_unaligned_le32(), so the output buffer need not be aligned. This is simpler, and on many CPUs it's the same speed. But, I kept the 'tmp' buffers in extract_crng_user() and _get_random_bytes() 4-byte aligned, since that alignment is actually needed for _crng_backtrack_protect() too. Reported-by:

[ Upstream commit c29de841 ] The PCI port driver saves the PCI state after initializing the device with the applicable service devices. This was, however, before the service drivers were even registered because PCI probe happens before the device_initcall initialized those service drivers. The config space state that the services set up were not being saved. The end result would cause PCI devices to not react to events that the drivers think they did if the PCI state ever needed to be restored. Fix this by changing the service drivers from using the init calls to having the portdrv driver calling the services directly. This will get the state saved as desired, while making the relationship between the port driver and the services under it more explicit in the code. Signed-off-by:

However, for symmetry, do like we do for ETS configuration, and call mlxsw_sp_port_ets_maxrate_set() for both TC i and i + 8. Signed-off-by:

[ Upstream commit d1befa65 ] vdso_fault used is_compat_task function (on s390 it tests "current" thread_info flags) to distinguish compat tasks and map 31-bit vdso pages. But "current" task might not correspond to mm context. When 31-bit compat inferior is executed under gdb, gdb does PTRACE_PEEKTEXT on vdso page, causing vdso_fault with "current" being 64-bit gdb process. So, 31-bit inferior ends up with 64-bit vdso mapped. To avoid this problem a new compat_mm flag has been introduced into mm context. This flag is used in vdso_fault and vdso_mremap instead of is_compat_task. Signed-off-by:

[ Upstream commit 49dd8054 ] If initialize client failed or finish uninitializing client, we should clear the client pointer. It may cause unexpected result when use uninitialized client. Meanwhile, we also should check whether client exist when uninitialize it. Fixes: 46a3df9f ("net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer Support") Signed-off-by:
