* [uaccess] Remove trivial uses of userptr_tMichael Brown2025-04-241-0/+1

* [acpi] Remove userptr_t from ACPI table parsingMichael Brown2025-04-221-4/+5
| | | | | | | Simplify the ACPI table parsing code by assuming that all table content is fully accessible via pointer dereferences. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [uaccess] Remove redundant user_to_virt()Michael Brown2025-04-211-1/+1
| | | | | | | | | The user_to_virt() function is now a straightforward wrapper around addition, with the addend almost invariably being zero. Remove this redundant wrapper. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [linux] Validate length of ACPI table read from sysfsMichael Brown2021-03-031-0/+10
| | | | | | | | | | | | | Consumers of acpi_find() will assume that returned structures include a valid table header and that the length in the table header is correct. These assumptions are necessary when dealing with raw ACPI tables, since there exists no independent source of length information. Ensure that these assumptions are also valid for ACPI tables read from sysfs. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [linux] Use generic sysfs mechanism to read ACPI tablesMichael Brown2021-03-031-78/+21Star

* [linux] Free cached ACPI tables on shutdownMichael Brown2021-03-031-0/+22
| | | | | | | Free any cached ACPI tables for the sake of neatness (and a clean report from Valgrind). Signed-off-by: Michael Brown <mcb30@ipxe.org>
