x86: fix whitespace in runtime-const assembler output 2024-10-25T16:53:03+00:00 Linus Torvalds torvalds@linux-foundation.org 2024-10-24T20:23:56+00:00 4dc1f31ec3f13a065c7ae2ccdec562b0123e21bb The x86 user pointer validation changes made me look at compiler output a lot, and the wrong indentation for the ".popsection" in the generated assembler triggered me.

runtime constants: add x86 architecture support 2024-06-19T19:34:34+00:00 Linus Torvalds torvalds@linux-foundation.org 2024-06-10T19:32:14+00:00 e3c92e81711d14b46c3121d36bc8e152cb843923 This implements the runtime constant infrastructure for x86, allowing the dcache d_hash() function to be generated using as a constant for hash table address followed by shift by a constant of the hash index.
