  linux-user/hppa: lock both words of function descriptor (2023-09-19 21:12:18 +0200)

----------------------------------------------------------------
Block-TLB support and linux-user fixes for hppa target

All 32-bit hppa CPUs allow a fixed number of TLB entries to have a
different page size than the default 4k.
Those are called "Block-TLBs" and are created at startup by the
operating system and managed by the firmware of hppa machines
through the firmware PDC_BLOCK_TLB call.

This patchset adds the necessary glue to SeaBIOS-hppa and
qemu to allow up to 16 BTLB entries in the emulation.

Two patches from Mikulas Patocka fix signal delivery issues
in linux-user on hppa.

----------------------------------------------------------------

Helge Deller (6):
  target/hppa: Update to SeaBIOS-hppa version 9
  target/hppa: Allow up to 16 BTLB entries
  target/hppa: Report and clear BTLBs via fw_cfg at startup
  target/hppa: Add BTLB support to hppa TLB functions
  target/hppa: Extract diagnose immediate value
  target/hppa: Wire up diag instruction to support BTLB

Mikulas Patocka (2):
  linux-user/hppa: clear the PSW 'N' bit when delivering signals
  linux-user/hppa: lock both words of function descriptor
