2022-09-09arm64/sysreg: Standardise naming of ID_AA64MMFR0_EL1.ASIDBitsMark Brown4-8/+8
For some reason we refer to ID_AA64MMFR0_EL1.ASIDBits as ASID. Add BITS into the name, bringing the naming into sync with DDI0487H.a. Due to the large amount of MixedCase in this register which isn't really consistent with either the kernel style or the majority of the architecture the use of upper case is preserved. No functional changes.

All non-UAPI asm/termios.h consist of include of UAPI counterpart and, possibly, include of linux/uaccess.h The latter can't be simply removed, even though nothing in linux/termios.h doesn't depend upon it anymore - there are several places that rely upon that indirect chain of includes to pull linux/uaccess.h. So the include needs to be lifted out of there - we lift into tty_driver.h, serdev.h and places that pull asm/termios.h, but none of * linux/uaccess.h (obvious) * net/sock.h (pulls uaccess.h) * linux/{tty,tty_driver,serdev}.h (tty.h pulls tty_driver.h) That leaves us just with the include of UAPI asm/termios.h, which is what <asm/termios.h> will resolve to if we simply remove non-UAPI header.

2022-09-09termios: consolidate values for VDISCARD in INIT_C_CCAl Viro4-7/+7
On old systems it used to be ^O. Linux had never actually used the value, but INIT_C_CC (on i386) did initialize it to ^O; unfortunately, it had a typo in the comment claiming that to be ^U. Most of the architectures copied the (correct) definition along with mistaken comment. alpha, powerpc and sparc tried to make the definition match comment. However, util-linux still resets it to ^O on any architecture, ^O is the historical value, kernel ignores it anyway and finally, Linus said "Just change everybody to do the same, nobody cares about VDISCARD".

2022-09-08x86/sgx: Do not fail on incomplete sanitization on premature stop of ksgxdJarkko Sakkinen1-6/+9
Unsanitized pages trigger WARN_ON() unconditionally, which can panic the whole computer, if /proc/sys/kernel/panic_on_warn is set. In sgx_init(), if misc_register() fails or misc_register() succeeds but neither sgx_drv_init() nor sgx_vepc_init() succeeds, then ksgxd will be prematurely stopped. This may leave unsanitized pages, which will result a false warning. Refine __sgx_sanitize_pages() to return: 1. Zero when the sanitization process is complete or ksgxd has been requested to stop. 2. The number of unsanitized pages otherwise.

If allocating memory for the target SVE state in za_set() fails we clear TIF_SME for the ptracing task which is obviously not correct. If we are here we know that the target task already had neither TIF_SVE nor TIF_SME set since we only need to allocate if either the target had not used either SVE or SME and had no need to allocate state before or we just changed the vector length with vec_set_vector_length() which clears TIF_ for us on allocation failure so just remove the clear entirely.

2022-09-08powerpc/64s: add pte_needs_flush and huge_pmd_needs_flushNicholas Piggin2-0/+59
Allow PTE changes to avoid flushing the TLB when access permissions are being relaxed, the dirty bit is being set, and the accessed bit is being changed. Relaxing access permissions and setting dirty and accessed bits do not require a flush because the MMU will re-load the PTE and notice the updates (it may also cause a spurious fault). Clearing the accessed bit does not require a flush because of the imprecise PTE accessed bit accounting that is already performed, as documented in ptep_clear_flush_young(). This reduces TLB flushing for some mprotect(2) calls.

2022-09-07perf/x86/intel: Optimize FIXED_CTR_CTRL accessKan Liang2-9/+17
All the fixed counters share a fixed control register. The current perf reads and re-writes the fixed control register for each fixed counter disable/enable, which is unnecessary. When changing the fixed control register, the entire PMU must be disabled via the global control register. The changing cannot be taken effect until the entire PMU is re-enabled. Only updating the fixed control register once right before the entire PMU re-enabling is enough. The read of the fixed control register is not necessary either. The value can be cached in the per CPU cpu_hw_events. Test results: Counting all the fixed counters with the perf bench sched pipe as below on a SPR machine. $perf stat -e cycles,instructions,ref-cycles,slots --no-inherit -- taskset -c 1 perf bench sched pipe The Total elapsed time reduces from 5.36s (without the patch) to 4.99s (with the patch), which is ~6.9% improvement.
