[PATCH 08/17] perf tools: Add 'perf -vv' as an alias to 'perf version --build-options'

From: Jin Yao We keep having bug reports that when users build perf on their own, but they don't install some needed libraries such as libelf, libbfd/libibery. The perf can build, but it is missing important functionality. This patch provides a new option '-vv' for

[PATCH 10/17] perf hists browser: Rename perf_evsel_browser_title to a more descriptive name

From: Arnaldo Carvalho de Melo Rename it to hists_browser__scnprintf_title() to better reflect that it provides a scnprintf-like function operating on a hists_browser instance. This paves the way to have a non-hists_browser specific function to scnprintf format a title with per

From: Arnaldo Carvalho de Melo This will be useful for the annotate browser as well, that wants to have extra title lines, i.e. the current ui_browser unconditionally reserves the first line for a browser title and the last one for status messages. But some browsers, like the

[PATCH 07/17] perf version: Print the compiled-in status of libraries

From: Jin Yao This patch checks the values passed by CFLAGS (-DHAVE_XXX) and then print the status of libraries. For example, if HAVE_DWARF_SUPPORT is defined, that means the library "dwarf" is compiled-in. The patch will print the status "on" for this library otherwise

[PATCH v6 2/5] arm: arm64: page_alloc: reduce unnecessary binary search in memblock_next_valid_pfn()

Commit b92df1de5d28 ("mm: page_alloc: skip over regions of invalid pfns where possible") optimized the loop in memmap_init_zone(). But there is still some room for improvement. E.g. if pfn and pfn+1 are in the same memblock region, we can simply pfn++ instead of doing the binary search in
