On linux-next, I get a build failure in some configurations:
drivers/perf/arm_spe_pmu.c: In function 'arm_spe_pmu_setup_aux':
drivers/perf/arm_spe_pmu.c:857:14: error: implicit declaration of function 'vmap'; did you mean 'swap'? [-Werror=implicit-function-declaration]
buf->base = vmap(pglist, nr_pages, VM_MAP, PAGE_KERNEL);
^~~~
swap
drivers/perf/arm_spe_pmu.c:857:37: error: 'VM_MAP' undeclared (first use in this function); did you mean 'VM_MPX'?
buf->base = vmap(pglist, nr_pages, VM_MAP, PAGE_KERNEL);
^~~~~~
VM_MPX
drivers/perf/arm_spe_pmu.c:857:37: note: each undeclared identifier is reported only once for each function it appears in
drivers/perf/arm_spe_pmu.c: In function 'arm_spe_pmu_free_aux':
drivers/perf/arm_spe_pmu.c:878:2: error: implicit declaration of function 'vunmap'; did you mean 'iounmap'? [-Werror=implicit-function-declaration]
vmap() is declared in linux/vmalloc.h, so we should include that header file.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
