It also refactors the get value flow in xl to make it be suitable for all allocation features. Based on that, a new MBA get value command is added in xl. Signed-off-by: Yi Sun Acked-by: Wei Liu Reviewed-by: Roger Pau Monné --- CC: Ian Jackson CC: Wei Liu CC: Roger Pau Monné CC: Chao Peng v6: - fix one coding style issue. (suggested by Roger Pau Monné) v5: - start a newline for "CDP" because it exceeds 80 characters. (suggested by Roger Pau Monné) - remove a duplicated ';'. (suggested by Roger Pau Monné) - remove a extra newline. (suggested by Roger Pau Monné) - correct words in log message. (suggested by Roger Pau Monné) v4: - use designated initializers for 'feat_name[]'. (suggested by Roger Pau Monné) - use LOG in 'libxl__psr_alloc_log_err_msg'. (suggested by Roger Pau Monné) v3: - replace 'libxl_psr_cbm_type' to 'libxl_psr_type' in newly defined interfaces. (suggested by Roger Pau Monné) v2: - change 'CAT_INFO'/'MBA_INFO' to 'CAT'/'MBA'. The related structure names are changed too.
