The H_GET_24X7_CATALOG_PAGE hcall can return a signed error code, so fix this in the code. The H_GET_24X7_DATA hcall can return a signed error code, so fix this in the code. Also, don't truncate it to 32 bit to use as return value for make_24x7_request. In case of error h_24x7_event_commit_txn passes that return value to generic code, so it should be a proper errno. The other caller of make_24x7_request is single_24x7_request, whose callers don't actually care which error code is returned so they are not affected by this change. Finally, h_24x7_get_value doesn't use the error code from single_24x7_request, so there's no need to store it.

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.
